In WSL2: Ubuntu 20.04 for Windows 10 nodejs is installed but npm is not working

问题

I am using WSL2: Ubuntu 20.04 in my Windows 10 operating system. I have installed nodejs using the command sudo apt-get install -y nodejs when I do node -v command I get v12.18.3

mrd@DESKTOP-2EO5K4H:/mnt/c/Users/musfi$ node -v
v12.18.3

but when I do npm -v command I get this below command

mrd@DESKTOP-2EO5K4H:/mnt/c/Users/musfi$ npm -v
-bash: /mnt/c/Program Files/nodejs/npm: /bin/sh^M: bad interpreter: No such file or directory

I also do whereis command. Hope this will help to find solution.

mrd@DESKTOP-2EO5K4H:/mnt/c/Users/musfi$ whereis node
node: /usr/bin/node /usr/include/node /mnt/c/Program Files/nodejs/node.exe /usr/share/man/man1/node.1.gz

mrd@DESKTOP-2EO5K4H:/mnt/c/Users/musfi$ whereis npm
npm: /usr/bin/npm /mnt/c/Program Files/nodejs/npm /mnt/c/Program Files/nodejs/npm.cmd /usr/share/man/man1/npm.1

I have tried almost all the stackoverflow solutions and github issues but nothing is worked for me.
Hope any kind soul has the solution to this problem. Thanks in advance.

Try this

export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
sudo apt install npm

回答2:

For all Unix/Linux/MacOS operating systems, I would always rather go with the "Node Version Manager". It normally works flawlessly on Linux and MacOS (and there's a Windows port for it as well) and enables a very simple way of installing node and npm correctly without the need of being root.

See here: https://github.com/nvm-sh/nvm

I can confirm here on my machine that it also works on Ubuntu 20.04 on WSL2.

Solution for following error: -bash: /mnt/c/Program Files/nodejs/npm: /bin/sh^M: bad interpreter: No such file or directory

Edit ~/.bashrc Append at end of file:

# strip out problematic Windows %PATH%
PATH=$(echo "$PATH" | sed -e 's/:\/mnt.*//g')

Now npm init will work.
