Ubuntu in Windows (WSL2) Adding C: in front of /mnt/c/ path? - environment-variables

Question

I just installed WSL2 and Ubuntu as one of my terminal options in Windows Terminal, as I want to now do my JavaScript development in Windows instead of Mac (our clients are all Windows users).
When I try to build my Node package with "npm run build", which is just a script of "babel lib -d dist", I receive the following error, which suggests to me either Windows, the WSL2, or something in my environment variables is pushing a "C:" in front of "\mnt\c", generating the following error:
internal/modules/cjs/loader.js:883
throw err;
^
**Error: Cannot find module 'C:\mnt\c\Program Files\nodejs\node_modules\npm\bin\npm-cli.js'**
at Function.Module._resolveFilename (internal/modules/cjs/loader.js:880:15)

}
And here is my PATH with 'printenv' in Ubuntu:
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/wsl/lib:/mnt/c/Program Files (x86)/Common Files/Oracle/Java/javapath:/mnt/c/Program Files/VanDyke Software/Clients/:/mnt/c/Program Files (x86)/Razer Chroma SDK/bin:/mnt/c/Program Files/Razer Chroma SDK/bin:/mnt/c/Program Files (x86)/Razer/ChromaBroadcast/bin:/mnt/c/Program Files/Razer/ChromaBroadcast/bin:/mnt/c/Windows/system32:/mnt/c/Windows:/mnt/c/Windows/System32/Wbem:/mnt/c/Windows/System32/WindowsPowerShell/v1.0/:/mnt/c/Windows/System32/OpenSSH/:/mnt/c/Program Files (x86)/NVIDIA Corporation/PhysX/Common:/mnt/c/Program Files/NVIDIA Corporation/NVIDIA NvDLISR:/mnt/c/Windows/system32/config/systemprofile/AppData/Local/Microsoft/WindowsApps:/mnt/c/Users/csomm/AppData/Roaming/nvm:/mnt/c/Program Files/nodejs:/mnt/c/Program Files/Git/cmd:/mnt/c/Program Files/Git/mingw64/bin:/mnt/c/Program Files/Git/usr/bin:/mnt/c/Program Files (x86)/QuickTime/QTSystem/:/mnt/c/Program Files/Docker/Docker/resources/bin:/mnt/c/ProgramData/DockerDesktop/version-bin:/mnt/c/Users/csomm/AppData/Local/Microsoft/WindowsApps:/mnt/c/Users/csomm/AppData/Local/atom/bin:/mnt/c/Users/csomm/AppData/Roaming/nvm:/mnt/c/Program Files/nodejs:/mnt/c/Program Files/JetBrains/WebStorm 2021.3.1/bin:/mnt/c/Users/csomm/AppData/Local/Programs/Hyper/resources/bin:/snap/bin
Any thoughts/ideas?

This has been resolved. The problem was that I had installed NVM/NPM first in Command Prompt, and owing to Windows WSL2 cross-utilizing Linux and Windows applications, NVM that was installed in Windows would run in my Ubuntu just fine, but the NPM would fail owing to relative path issue.
Solution was to "re-install" NPM natively within Ubuntu. Now it works perfectly.
