如何在 AWS CloudShell 中安装 npm？

Question

I'm trying to install an npm package in the new AWS CloudShell (comes with pre-configured Node.js support ) - but I'm getting a EACCESS error.

npm ERR! code EACCES
npm ERR! syscall access
npm ERR! path /usr/lib/node_modules
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, access '/usr/lib/node_modules'
npm ERR!  [Error: EACCES: permission denied, access '/usr/lib/node_modules'] {

npm ERR!   code: 'EACCES',
npm ERR!   syscall: 'access',
npm ERR!   path: '/usr/lib/node_modules'
npm ERR! }
npm ERR! 
npm ERR! The operation was rejected by your operating system.

What's the best way to install npm packages in AWS CloudShell?

To get around this problem, I followed the instructions at https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally :

First:

mkdir ~/.npm-global
npm config set prefix '~/.npm-global'

In your preferred text editor, open or create a ~/.profile file and add this line :

export PATH=~/.npm-global/bin:$PATH

Then:

source ~/.profile
