npx but use version in package json - npx

I have a build script in javascript project that uses parcel to iterate through folders and finding index files and then building those projects. When I find an index file I run this command:
npx parcel build ${indexFilePath} --out-dir ${outDir} --target node
But, if the person running this build script has not installed packages with npm i yet, the npx command will install the latest version of parcel-bundler, where --out-dir is now deprecated and breaking the entire script.
Here is what's going on, distilled:
$ rm -rf node_modules
$ npm i
$ npx parcel --version
1.12.4
$ rm -rf node_modules
$ npx parcel --version
2.0.0-beta.2
Is there any option for npx to use the version in the package.json file that is already in the project and install it to node_modules? Or do I just ingrate the install step into my build? It just seems overkill, since all I need to build is parcel.
Am I abusing npx by using it like this?

Multiple issues exist in npx regarding this problem : #199 & #15
The only option I found so far was to parse & extract version from my package.json using node repl (which should be available in your case)
Something like this :
npx parcel#`node -p -e "require('./package.json').dependencies['parcel']"` --version

How to use the brew version of a command (aws-es-proxy) instead of node?

I used npm -i -g aws-es-proxy. But I actually wanted to do brew install aws-es-proxy because the commands are slightly different for these two packages depending on whether installed with npm or brew. So I did npm uninstall -g aws-es-proxy and after uninstalling and deleting the folder that was still left over
$ cd /Users/USER_NAME/.nvm/versions/node/v10.17.0/bin/
$ ls
aws-azure-login node npm npx
bin USER_NAME$ rm -r aws-azure-login
I still would get
$ aws-es-proxy -listen :9200 -ENDPOINT
-bash: /Users/USER_NAME/.nvm/versions/node/v10.17.0/bin/aws-es-proxy: No such file or directory
It seems like this terminal is using npm version instead of brew version. Can you let me know how I can force to use the brew installation for this command?
Actually, all I had to do was open a new terminal session and it recognized the command. Not sure what behind the scenes stuff was happening.

I've installed Yarn at a global level. Why can't I see run yarn -v at a project level?

New to Yarn and I've installed it at global level npm install -g yarn
At ~ I can run yarn -v and see the version number fine.
However, when I cd into my project (currently just an empty folder on the desktop) and run yarn -v I get yarn: command not found.
Wouldn't having installed it globally allow me to run Yarn anywhere?

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

How to get the sources of a npm package locally when developing?

I am very new to node and npm and I am wondering if it is possible to work on a application, but also work on a local git repository for some node modules.
Let's say I am starting a new project that uses chalk and I would like to develop both on my project and on chalk.
mkdir my-project && cd my-project
npm install
npm install --save chalk/chalk
With the above command I will the source of chalk into node_modules but I cannot contribute to it.
Is there a way to directly get the Git repository?
Asumming '~/projects' is your projects folder, first clone chalk:
cd ~/projects
git clone https://github.com/chalk/chalk.git
Then create your project:
mkdir my-project && cd my-project
npm init
And set your project to use your local chalk. Look for package.json file inside my-project and include chalk in dependencies:
"dependencies": {
"chalk": "file:../chalk"
....
....
Then install chalk in your project:
cd ~/my-project
npm install chalk
Or simply 'npm install' to install all your dependencies. Every time you need to include in your project changes you made on chalk type again 'npm install chalk'. It copies ~/chalk on ~/my-project/node_modules and uses it.
You can continue working on your project and on chalk.

Why does "yarn install" raise an ENOENT error when installing esparse?

I have a JavaScript project using npm to manage its dependencies. I'm trying to migrate to Yarn.
When I run yarn install in the console, it gives me an error:
An unexpected error occurred: "ENOENT: no such file or directory,
chmod C:\....\node_modules\.bin\esparse"
From what I read on the yarn docs, just running yarn install should be enough. Why doesn't this work as expected?
I am using Yarn 0.17.0, npm 2.14.12 and Node 4.2.4.
The following Solution worked for me
rm -rf node_modules **/node_modules
rm -rf yarn.lock **/yarn.lock
yarn cache clean
yarn install
This is a pretty old question, but with latest yarn for now (1.17.3) the same problem arises.
The solution which works for me, although more time consuming, is to delete yarn.lock file.
Please keep in mind that afterward, all libraries will get updated to the latest versions according to the rules you specified in package.json file
I had a similar issue which was resolved by running the following commands:
npm install yarn -g --force
yarn --c
rm package-lock.json
rm yarn-lock.json
yarn install
