'NPM not found when using NVM

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 ?

node.jsnpmnvm

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.

If you run NVM-Windows, don't forget to run nvm on. (this solve the problem as title for me.)

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

I solved it by uninstalling all problematic node versions (e.g. v14 below) and reinstalling it.

The problem:

node --version; npm --version;

v14.17.1
Command 'npm' not found, but can be installed with:
sudo apt install npm

The solution:

nvm deactivate

echo "All versions BEFORE:"
nvm_ls

# uninstall all 14.* versions
for v in $(nvm_ls 14); do nvm uninstall $v; done

echo "All versions AFTER:"
nvm_ls

# reinstall version 14
nvm install 14

# and now it has npm too
node --version; npm --version
which node; which npm

# v14.17.1
# 6.14.13
# /home/user/.nvm/versions/node/v14.17.1/bin/node
# /home/user/.nvm/versions/node/v14.17.1/bin/npm

If you use Windows OS, make sure you removed the existing nodejs and npm. In my case, it worked well after I remove the C:/Program Files/nodejs. Reference is here.

During nvm installation, make sure the selected path must NOT exist.

Solution 7:[7]

For Windows:

nvm creating symlink from installed node path like c:\program files\node to the c:\users<your user>\AppData\nvm<node ver>

So check:

  1. Your basic node path in the PATH variable.
  2. Your npm is inside c:\users<your user>\AppData\nvm<node ver>\nmp and this path is also int the PATH variable.

One possible reason is the NVM symlink is invalid.

  1. But first, check if both NVM_HOME & NVM_SYMLINK is already set in environment path.
    If not, maybe some problem with your nvm installation and u might want to reinstall.
  2. Using explorer, open the symlink folder to check if the folder is valid.
    Default Symlink path in Windows: C:\Program Files\nodejs. Symlink appears as a normal shortcut in Windows explorer.
    If you see node files in there, then you're fine.
    If the folder is invalid, delete the symlink.
    Then, execute nvm ls and nvm use <desired node version>, this step will re-create the correct symlink.
  3. Restart CMD and test nvm current, node -v, npm -v

I went through a similar issue recently and solved it by setting the npm mirror to npm_mirror https://github.com/npm/cli/archive/refs/tags/

The default npm mirror (https://github.com/npm/cli/archive) was a broken link.

so run

nvm npm_mirror https://github.com/npm/cli/archive/refs/tags/

You could also run

source ~/.bashrc

and try to run again on the same bash terminal where you downloaded the install.sh the command:

npm -v

Solution 11:[11]

I had the same issue while any new terminal instance started up the message 'npm not found' was shown. I noticed that I had defined (probably) custom paths to npm and node in ~/.bashrc. Deleting them (keeping the paths for nvm) resolved the problem.
