I just tried to update my version of express to 4.0.0
I used sudo npm install -g express and I can see the newest version has already been installed on my laptop.
However, when I type express -v, the version is still 2.5.8. How to change it to 4.0.0?
Thank you
Express has removed the bundled generator from the main project, to update the express generator use this command:
$ sudo npm install -g express-generator
Then when you'll do express -V:
$ 4.0.0
You might get an error like:
Error: Refusing to delete: /usr/bin/express not in
/usr/lib/node_modules/express-generator
If you do, just uninstall the v3 express generator like:
$ sudo npm uninstall -g express
Then do the commands above again.
Something else seems wrong with your installation, force the deletion of express v3:
$ sudo rm -rf $(which express)

I've got nvm installed and I'm using node v10.24.1, npm v6.14.12, and I'm trying to upgrade yarn from 0.32 to 1.x
When I run npm install -g yarn I get
> yarn#1.22.15 preinstall /home/pmweeks/.nvm/versions/node/v10.24.1/lib/node_modules/yarn
> :; (node ./preinstall.js > /dev/null 2>&1 || true)
/home/pmweeks/.nvm/versions/node/v10.24.1/bin/yarn -> /home/pmweeks/.nvm/versions/node/v10.24.1/lib/node_modules/yarn/bin/yarn.js
/home/pmweeks/.nvm/versions/node/v10.24.1/bin/yarnpkg -> /home/pmweeks/.nvm/versions/node/v10.24.1/lib/node_modules/yarn/bin/yarn.js
+ yarn#1.22.15
updated 1 package in 1.851s
but then I run yarn --version and I get 0.32 still. I can run npm install -g yarn again and it will act like it's upgrading it again.
I've also tried sudo apt install yarn and sudo apt update \ sudo apt upgrade and still I'm on yarn 0.32
How can I upgrade yarn to 1.x with nvm installed? I suspect that the problem is something to do with nvm but I don't want to uninstall or switch node version managers if there's an easier way
Managed to get yarn version 1.x installed and working by following the instructions in the top answer to this question
I have installed Ubuntu Bash on Windows. I already have nodejs and npm on my windows machine at C:\Program Files\nodejs. In the bash shell in Windows, I am running a script which uses npm install command. The script is giving following error
: not foundram Files/nodejs/npm: 3: /mnt/c/Program Files/nodejs/npm:
: not foundram Files/nodejs/npm: 5: /mnt/c/Program Files/nodejs/npm:
/mnt/c/Program Files/nodejs/npm: 6: /mnt/c/Program Files/nodejs/npm: Syntax error: word unexpected (expecting "in")
Note: Before following the steps below, first try to restart your shell.
You can install Node.js and NPM with your Windows PowerShell as well, so if you've done that it won't work properly for your Subsystem. That means you have to install it twice (Powershell and Subsystem) or decide on one thing.
If the preceding text, has not helped you, this is how to solve the problem:
Remove your current installations
sudo apt-get --purge remove node
("sudo apt autoremove node" if console is asking for it)
sudo apt-get --purge remove nodejs
Install node the right way.
This is for version 14 (view current LTS version):
curl -fsSL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs
Then install build tools so you can install add-ons for npm later
sudo apt-get install -y build-essential
Now you can type in
npm -v
node -v
Same thing: nodejs -v
to check whether Node.js and NPM are installed correctly. If it shows nothing, restart the shell.
If it still shows the same error, restart the WSL/ PC or try with sudo npm -v
Here are two links that may also help you.
https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions
https://github.com/nodesource/distributions/blob/master/README.md#debinstall
Also, take a look at the Node Version Manager (NVM). With it, you can easily switch back and forth between versions.
The solution provided by phucanhapril on May 24, 2017 in this thread worked for me.
To summarise, edit ~/.profile and change your PATH to this:
PATH="$HOME/bin:$HOME/.local/bin:/usr/bin:$PATH"
(By default it does not include /usr/bin)
Then run:
source ~/.profile
I am not quite sure why npm doesn't work properly in the first place, or why /usr/bin isn't in PATH by default, but the solution worked for me.
I had the same problem to solve I installed "NVM" in my Subsystem
Follow these steps and see if it will solve for you:
sudo apt-get update
sudo apt-get install build-essential libssl-dev
curl -sL https://raw.githubusercontent.com/creationix/nvm/v0.31.0/install.sh -o install_nvm.sh
bash install_nvm.sh
source ~/.profile
nvm install 11.13.0
You can try sudo npm install it was a solution in my particular case.
Linux command for install nodejs and npm
sudo apt-get install nodejs
sudo apt-get install npm
Set path in linux
export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
reference
https://github.com/microsoft/WSL/issues/3882
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt-get install -y nodejs
this is enough, if you still face the problem
node installation needs restart, close you ubuntu window and start again it will solve your problem :)
I had the same problem. This is what I did.
Step 1. Type node -v and npm -v commands in Windows PowerShell and check if node and npm are properly installed
Step 2. Add this to the ~/.zshrc or ~/.bashrc file
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
Step 3. Type source ~/.zshrc and/or source ~/.bashrc
Step 4. Type node -v and npm -v commands in bash or zsh shells and the correct versions should now appear
On Visual Studio -> Tools -> Options -> Projects and Solutions -> Web Package Management -> make sure $(PATH) is above all the rest.
As long it is not located at the top of the list VS will try to use VS tools instead of npm.
You should also refer windows to the current npm version by following this screenshot, after try npm --version.
Changing npm path:
I had this issue in both Debian and Ubuntu (though in Ubuntu the nvm command did work) when I was running Windows 10 version 1703. Then when I upgraded to version 1903 the problem disappeared.
I had the same error and it may seem silly, but I fixed it by simply typing exit in the console and opening it again.
I received this error when I modified my "~/.bashrc" file to shorten up the bash directory.
At first I had:
if [ "$color_prompt" = yes ]; then
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u\[\033[00m\]:\[\033[01;34m\]\W\[\033[00m\]\$ '
else
PS1='${debian_chroot:+($debian_chroot)}\u\h:\W\$'
fi
....But then could not run any node operation. I rolled it back and the error stopped happening.
After some troubleshooting, I was able to fix the error by adding ~ before the $ on PS1='${debian_chroot:+($debian_chroot)}\u\h:\W\~$
I just read through many threads trying to do this. There is complete documentation for setting up node, nvm, and npm in wsl, here: https://learn.microsoft.com/en-us/windows/nodejs/setup-on-wsl2
If you already installed node and npm using the following commands,
sudo apt-get install nodejs
sudo apt-get install npm
NPM will not work. You must first uninstall them using:
sudo apt-get remove nodejs
sudo apt-get remove npm
Follow the guide to completely uninstalling here: How can I completely uninstall nodejs, npm and node in Ubuntu
Then reinstall from the windows guide referenced above.
The windows guide has many other useful resources.
The Tldr to install(from Microsoft Docs):
sudo apt-get install curl
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
nvm install --lts
I had identical output to that in the question. It occurs because Ubuntu on WSL adds Windows paths to the bash shell, but of course the Windows executables do not work in bash.
I installed nvm, and from there installed node into bash. NVM works out all the paths so it works.
I tried to use pip install, but it tells cannot find such package.
I also see someone say we can use brew and nodejs to install. This is what I tried to install brew
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
It returns that ruby doesn't found.
I have no idea about nodejs.
Anyone knows how can I install PhantomJS in the server?
Meet npm!
Npm stands for Node Package Manager.
You can install packages for using them from the CLI or from your nodejs app.
You can install NPM from here.
If node isn't installed yet, you can use NVM, which makes it really easy -
$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash
For your question,
See this specific package.
You can install it via:
$ npm install phantomjs-prebuilt
And then you should be able to: $ bin/phantomjs [phantom arguments] to run phantomJS from the terminal.
PhantomJS is a standalone application with its own website which has binaries for all major platforms and documentation. You don't really need pip or npm or bundler to install it, just do it manually.
Go to http://phantomjs.org/download.html
Choose the appropriate binary (Linux x32 x64 / OSX / Windows), download archive, extract it and run the binary.
For example you have a x64 Linux distribution.
Log in to your server via ssh.
Go to your home directory:
cd ~
Download PhantomJS binary:
wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2
Extract archive:
tar xvf phantomjs-2.1.1-linux-x86_64.tar.bz2
A new directory is created: phantomjs-2.1.1-linux-x86_64. The PhantomJS binary is phantomjs-2.1.1-linux-x86_64/bin/phantomjs. You can run it right now:
~/phantomjs-2.1.1-linux-x86_64/bin/phantomjs --version
2.1.1
(If it says "not found " instead that means you chose the wrong distribution, e.g. x64 instead of x32).
But this way of running it is inconvenient. It would be way better to be able to just type phantomjs script.js in any directory. To make it so add a link to a directory where binaries are kept by default:
sudo ln -s ~/phantomjs-2.1.1-linux-x86_64/bin/phantomjs /usr/bin/phantomjs
Then you can call PhantomJS from anywhere:
cd /var/www/
phantomjs --version
2.1.1
I used Homebrew to install yarn. Running yarn -v shows that I currently use 0.23.2. I ran brew upgrade yarn to get the latest version, which is 0.24.6.
After Homebrew successfully upgrades yarn, I run yarn -v again, but the version is still 0.23.2. How can I change the version of yarn that I am running?
yarn policies set-version <version number>
Per https://github.com/yarnpkg/yarn/issues/7146#issuecomment-477809216
You can use homebrew and yarn formula URLs to install older versions of yarn, then brew switch between yarn versions as needed. Works perfectly! Credit to github user robertmorgan.
First off, if you already have a version installed, unlink it from brew running the brew unlink yarn command in your terminal.
Next, in a web browser, find the Pull Request that has been merged which contained the formula (version) of
Yarn
that you want to install.
View the files changed in that Pull Request - there should be one for Formula/yarn.rb.
Click the "View" button for the Formula/yarn.rb file to see the whole contents of the file for that commit.
Click the button to view the "Raw" version of that file. This will open a url which should start with
https://raw.githubusercontent.com/....
This is the URL that you will need for the next step - so copy the complete URL to your clipboard.
Back in your terminal window, use the command brew install followed by the URL that you've copied.
e.g. to install v1.6.0 of yarn it would be:
brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/fba7635ab69384ac980c635483a7af825bc06088/Formula/yarn.rb
You can then verify the versions available to Homebrew by running:
brew list --versions yarn, and switch between versions using brew switch yarn VERSION_NUMBER
Source: https://github.com/yarnpkg/yarn/issues/1882#issuecomment-421372892
I found an answer. It's not the prettiest, but since yarn always tell me what the most update-to-date version is, I can use npm to just install the latest version.
If the latest is 0.24.6
npm install --global yarn#.24.6
EDIT:
According to yarn's official documentation, the way to install/upgrade is:
brew install yarn
brew upgrade yarn
https://yarnpkg.com/en/docs/install#mac-stable
Your best bet would be to use a yarn version manager.
Install:
curl -fsSL https://raw.githubusercontent.com/tophat/yvm/master/scripts/install.sh | bash
Single usage:
yvm exec <version> <command>
Or to switch your currently running yarn version
yvm use <version>
yarn --version
UPDATE Dec 2021:
Sadly brew switch is deprecated in Homebrew 2.6.0 (December 2020)
$ brew switch
Error: Unknown command: switch
TLDR, to switch version:
brew unlink yarn
brew link yarn#<new_version>
Old solution:
Assuming that you have the other version installed, you can run
brew switch yarn <old_version>
To list the versions you have installed:
brew list --versions yarn
You can use
yarn set version <version>
For example, if you want the latest version, you can run
yarn set version latest
You can also set it to a specific number, for example,
yarn set version 1.22.1
You can view the full documentation at the official website.
Note 1: A bug stops you from switching from yarn 2 to yarn 1. There are solutions to this in this GitHub issue.
Note 2: I don't use brew, but this solution should still work.
Easily install and switch between any number of yarn versions.

Here's a way to do it with only curl and bash:
curl -o- -L https://yarnpkg.com/install.sh | bash -s -- --version 0.24.6 # or another version
This works whether you have yarn installed or not.
For updating version on macOS use below command:
$ brew upgrade yarn
Some of the above answers don't seem to work anymore. Here is how I was able to install a different version in April 2021:
brew unlink yarn#1.6.0 (If you already have a version installed)
brew extract --version 1.22.4 yarn homebrew/cask
brew install yarn#1.22.4
yarn -v
After installing n by command 'sudo npm install -g n',
I want list all node versions,but some errors come out, even though, n can work normally!
As bellow:
$ n list
/usr/bin/n: line 262: which: command not found
/usr/bin/n: line 262: which: command not found
0.0.1
0.0.2
0.0.3
0.0.4
I don't know why, there is no need to configure my bin foldeer.
I have solved it, after npm install which...
sudo npm install -g whitch
Try installing which
sudo apt-get install which
This is fixed in the current version of n.
Old versions of n used the which command which is not standard. Newer versions only use command -v which is a standard posix command.
