Installing npm globally - npm

Is it possible to install npm globally and is this a good idea?
I installed npm with the npm install command and was able to run npm start. Then after publishing my project to github I wanted to make sure it would run if someone cloned it, so I cloned it to a different directory on my machine. I then had to run npm install again to install the dependencies. Is it necessary to do this for each project you build locally or is it better and possible to install it globally on your machine?
Thanks

Command line for install npm globally--
npm install -g <package>
For more read from here.
In general, the rule of thumb is:
If you’re installing something that you want to use in your program,
using require('whatever'), then install it locally, at the root of
your project.
If you’re installing something that you want to use in your shell, on
the command line or something, install it globally, so that its
binaries end up in your PATH environment variable.
Details you can read here.

To install a module from npm globally, you'll simply need to use the --global flag when running the install command to have the module install globally, rather than locally (to the current directory).
you can use command:
npm install <module> --globalor npm install <module> -g
note: <module> is the name of the module you want to install globally

Yarn Installation not brings Vue files

As a newbie, i am trying to properly install yarn via VsCode terminal, and having an issue;
I use
yarn add -g #vue/cli
command to install, after installation i am still not able to use vue ui command(throws: the term ‘vue’ is not recognized as the name of a cmdlet…’), so it made me think of the vue.cmd not installed in my system, then i check my npm directory, i can see 3 different yarn files, but no vue files at all..
I have been using npm before and already uninstalled before yarn installation, with following command:
npm uninstall -g #vue/cli
After uninstalling npm, the vue files in npm directory are gone, as expected.
Is there any other step that I should take to install vue.cmd files(if its necessary)?
Maybe i should not have to uninstall npm, becacuse npm installation brings vue files into my system?
Thank you in advance,
Instead of using:
yarn add -g #vue/cli
Use this command:
yarn global add #vue/cli
Note: If you are on windows you have to use CMD to run vue cli commands. As by default PowerShell doesn't allow to run packages that were installed globally via npm or yarn. You may need to disable PowerShell security to use that package in PowerShell. But I recommend you to use cmd to use the package after installation. But still, you can install the package via PowerShell.

Command not found with vue-cli

While installing the dependencies of vue-cli, vue is not identified. Why?
rm -rf node_modules and npm install again
have a look here
Add sudo before yarn when installing
yarn global remove #vue/cli
sudo yarn global add #vue/cli
vue
I had the same issue for a while.
TL;DR
npm install #vue/cli-service --save-dev
As the documentation specify it is a development dependency https://cli.vuejs.org/guide/#cli-service
The CLI Service (#vue/cli-service) is a development dependency. It's an npm package installed locally into every project created by #vue/cli.
Origin
I had a fresh install of nodejs
And just did
>> sudo npm install -g #vue/cli#latest
>> vue --version
#vue/cli 4.5.8
The issue
The issue presented like this
>> npm run serve
yarn run v1.22.10
$ vue-cli-service build --mode development --watch
/bin/sh: 1: vue-cli-service: not found
error Command failed with exit code 127.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
The fixes:
npm install #vue/cli-service --save-dev
Which led me straight to another error message
>> npm run serve
yarn run v1.22.10
$ vue-cli-service build --mode development --watch
ERROR Error: Cannot find module 'vue-template-compiler/package.json'
Which I fixed the same way
npm i vue-template-compiler --save-dev
And now it is working fine.
Installing current version without permanently installing vue-cli.
npx #vue/cli create appname
It shows the vue executable is located at /home/alisha/.local/bin. So probably this location is not there in your $PATH.
You should be able to run the vue commands if you provide the full path, like:
~/.local/bin/vue create hello-world
You can also see if that directory is in your PATH by running some command like:
echo $PATH | grep '.local/bin/'
If it's there, you would see it, otherwise you can add it to your path by placing it in your ~/.profile.
Edit ~/.profile and add the following at the bottom of it.
PATH="$HOME/.local/bin:$PATH"
Hope it helps!!
I had the same issue while making a build for production.
You will require vue-cli to be installed. Use below command to install the latest version.
npm install -g #vue/cli#latest
Then
npm install
Might have to do with you having an old version on your computer:
Warning regarding Previous Versions
The package name changed from vue-cli to #vue/cli. If you have the previous vue-cli (1.x or 2.x) package installed globally, you need to uninstall it first with
npm uninstall vue-cli -g or yarn global remove vue-cli.
You can find it here: https://cli.vuejs.org/guide/installation.html
THIS FIXED THE ISSUE FOR ME:
After running
sudo npm install -g #vue/cli
I ran
sudo nano $HOME/.profile
and pasted the following line
export PATH=$PATH:/home/chike/.npm-global/bin
after writing the code, next thing I did was Ctrl + O, ENTER and Ctrl + X then wrote
vue init webpack myapp
When you install vue using cli that time you got the path of vue.Now you can copy the bin folder path.
In my example /home/sublime/.npm-packages/bin
Now you export the path below command
export PATH=$PATH:/home/sublime/.npm-packages/bin
I solved mine by running (add sudo if needed)
npm i -g vue-cli#2.9.6
npm i -g #vue/cli
Got similar issue when deploy vue project in jenkins.
Here is what I did:
Add node's bin/ dir, to jenkins user's .bashrc file.
e.g
# node
NODE_HOME=/home/dev/.nvm/versions/node/default
PATH=$NODE_HOME/bin:$PATH
Tips - about nvm & yarn
When you manage node version via nvm, make sure you already choose the node version in terminal. e.g:
nvm use stable
node -v
If you use nvm, and installed yarn via npm, then better install vue-cli via npm not yarn, otherwise the vue executable is not placed into node's bin/ dir, at least that's the case in my tests, and as a result will cause you fail to find the vue command.
Using Yarn on Ubuntu it is installed to ~/.npm-packages/bin/. You must add this directory to your PATH. For example run the following command, close your terminal and open a new one.
user#machine:~$ echo 'export PATH="$PATH:~/.npm-packages/bin/"' >> ~/.bashrc
Note: if the file ~/.bashrc does not exist then simply create it.
Following worked for me:
First remove all the existing ones:
yarn global remove #vue/cli
yarn global remove #vue/cli-service
sudo yarn global remove #vue/cli
sudo yarn global remove #vue/cli-service
Then add #vue/cli using sudo:
Note: use sudo if required
yarn global add #vue/cli
yarn global add #vue/cli-service
Then, the final thing to do is to RESTART the terminal.
vue --version
#vue/cli 4.5.9
If you already got a project, the only two things you need to do is:
Delete the directory node_modules (it is safe, since it is not under git and will regenerate in the next step)
In the command-line write yarn install (it will install everything you need)
If you start installing vue-cli manually in a existing project, it the package.json and package-lock.json will be updated. If you already did. Do a checkout from git, and follow my steps above
This may be a problem caused by version conflicts. "export PATH=$PATH:" This is really useful in some cases. But if you are also like me, after trying the direct “export path” method in the comment above, restarting the terminal still can not execute the situation, you can try this way.
Uninstall Vue
npm uninstall -g #vue/cli
Check the local-global npm package installation path, vue is installed in this directory, check if it has been removed.
npm root -g
Install vue (you can check with https://cli.vuejs.org/#getting-started to find the latest command)
npm install -g #vue/cli
Create a connection to the /usr/local/bin directory(You need to find the vue.js path after the local installation first, then replace this path with your latest local install path:/Users/xxxxx/.npm-global/lib/node_modules/#vue/cli/bin/vue.js)
ln -s /Users/xxxxx/.npm-global/lib/node_modules/#vue/cli/bin/vue.js /usr/local/bin/vue
View version number
vue -v
I was getting the same error because Node.js was not installed. My issue got resolved by installing Node.js using the following command:
sudo apt install nodejs-legacy
To see if you already have Node.js and npm installed and check the installed version, run the following commands:
node -v
npm -v
If both are installed then follow the steps here:
https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally
I installed the package using yarn global add #vue/cli on my Ubuntu box and found the binary in /home/vonkad/.yarn/bin.
I had to modify my /home/vonkad/.bashrc and add the directory to the path export PATH=$PATH:/home/vonkad/.yarn/bin.
To fix this situation, I had to add the following line to my .zshrc (maybe in your case is .bashrc)
export PATH="$(yarn global bin):$PATH"
Effectively, the yarn global bin is a folder where vue (vue-cli 3) was placed.
What helped me
mac os catalina with zsh terminal
Uninstalled node and npm using https://www.positronx.io/how-to-uninstall-node-js-and-npm-from-macos/
Downloaded node/npm from https://nodejs.org/en/download/current/
sudo npm install -g #vue/cli
vue --version (#vue/cli 4.5.4)
I faced the same issue and now resolved. In my case I installed Node.js and NPM using the default Ubuntu repository by using this command sudo apt-get install nodejs npm
The problems seemed like those 2 packages are not well maintained so it caused some bugs.
So I purge those packages and reinstall it from nodesource which is officially recommended way to install (reference: Installation instruction from nodesource) using these commands.
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs
Then reinstall #vue/cli again
sudo npm install -g #vue/cli
Now these issues have gone. Hope it helps some programmers.
You need to install vue via sudo like explained in the doc:
https://cli.vuejs.org/guide/installation.html
If you have WSL2 running and you use zsh like me, just add
yarn global add #vue/cli
# add this line to ~/.zshrc
export PATH="$HOME/.yarn/bin:$PATH"
$ vue --version
#vue/cli 4.x.xx
You can try the following code install see
npm install --global vue-cli
vue init webpack <YOUR-PROJECT-NAME-HERE>
cd <YOUR-PROJECT-NAME-HERE>
npm install
npm run dev

Cannot get "npm install #feathers/cli -g" to work in the command line

I get this error message when I try installing feathers from npm
npm WARN deprecated nomnom#1.8.1: Package no longer supported. Contact support#npmjs.com for more info.
npm WARN deprecated babel-preset-es2015#6.24.1: 🙌 Thanks for using Babel: we recommend using babel-preset-env now: please read babeljs.io/env to update!
Help!!
As Vasan pointed out in the comments, running
npm install -g #feathersjs/cli
from the command prompt on Windows installs a file feathers.cmd in the folder:
%APPDATA%\npm
If this folder is not on your PATH, then feathers will not be recognised as an executable - it appears that the global install doesn't add it to the path automatically.
Editing system environment variables to add this folder to your path should make the feathers cli tools available.
Note that after altering your path you may need to restart your terminal for the updated path to be available.
Its very simple, if you have an earlier version installed, uninstall the old feathers-cli using:
npm uninstall feathers-cli -g
Then install #feathersjs/cli and upgrade a project by the following commands:
npm install #feathersjs/cli -g
cd path/to/project
feathers upgrade
I also faced with the installation issue. But got an error: 404 Not Found: babel-messages#^6.23.0. I've solved it when run npm install #feathersjs/cli -g through the windows terminal (cmd). Before that I was running it on bash.
This issue also occurs when installation is ran using Admin credential(Windows 10), reinstall without elevated cmd/powershell credential also solved the problem.

package.json for global modules - not dependencies

I would like to list some modules that I want to install globally - they are not project related (things like bower, npm-check-updates, ... which I use all the time). Is it possible to manage this with a "global" package.json, or do I need to maintain a separate shell script to perform this installation? Currently I am doing:
# global-npm-pacakges.sh
npm install -g npm-check-updates#1.5.1
npm install -g bower#1.4.1
Any other way of doing this?
Your way is fine but that means you also need to maintain another script to
uninstall all of them globally
Using npm install -g with a global package.json, you still have to manage a clean up script.
There is no npm uninstall -g based on the package.json.
I think you need to
npm uninstall name<#version> or
npm -R name<#version>
Doing npm -R node_modules is not gracefully way of doing it.
It does not clean up the /tmp/xxx
There is some suggestions of using a symlink in this threads for your references:
How do I install a module globally using npm?

When installing locally (npm install .), can I have npm use my global packages?

When I run npm install . it takes a while to build packages that contain c code like expresso (which depends on node-jscoverage). I realized that I can copy expresso from my global package directory (~/Developer/lib/node_modules/expresso) to ./node_modules/expresso in my current directory before running npm install . and it won't bother compiling it. Is there a way to tell npm to try to install packages from my global npm directory before fetching and building them?
I guess this command might help: npm link
