I started a new project and wanted to use node/npm inside of WSL2. However, when I tried to run npm inside of either Ubuntu 18 or 20, I got this error message:
-bash: /mnt/c/Program Files/nodejs/npm: /bin/sh^M: bad interpreter: No such file or directory
After a whole lot of searching, I came across this web page, https://stackoverflow.com/questions/63716587/in-wsl2-ubuntu-20-04-for-windows-10-nodejs-is-installed-but-npm-is-not-working which suggested updating the ~/.bashrc file to look like:
# strip out problematic Windows %PATH% PATH=$(echo "$PATH" | sed -e 's/:\/mnt.*//g')
I added that to the VERY end of the file, and rebooted.
The next time I tried to run npm, I got this successful message instead:
