NPM not found when using NVM

问题

I have installed node/npm using the nvm documentation.

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.29.0/install.sh | bash

Then:

nvm install node

At this point node is working but the npm command result with:

npm: command not found

How can I have npm to work correctly ?

回答1:

I found out that this was a conflict with a previous versions of npm that have not been removed properly despite a apt-get remove node.

I solved it by reinstalling npm from scratch:

rm -R ~/.npm ~/.nvm
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
nvm install node

I found the solution here.

I fixed this by doing this command:

$ command -v npm

and then reopen the shell window.

This problem especially happens in windows which happens because of missing admin rights for cmd.

If you are using Git bash

1. Go in installation directory e.g C:\Program Files\Git
2. Right click properties -> compatibility.
3. Tick the checkbox with label -> Run as administrator.
4. Run the git bash again & execute npm list and then npm use 'version_to_be_used'

Same goes for Cmd

Install node using node source distribution:

curl -sL https://deb.nodesource.com/setup_[version].x | bash -
apt-get install -y nodejs

[version] = the wanted version. See the repository to choose the correct: NodeSource Node.js Binary Distributions
