CODE EXAMPLE FOR SHELL

/usr/bin/env: ‘bash ’: No such file or directory

This is a line endings issue, but not from Ubuntu. Make sure you do have node and npm installed correctly by using the command:

sudo apt install nodejs npm

Then stop Windows path variables being shared with WSL by editing the /etc/wsl.conf file in WSL. If the file doesn't exist, execute sudo touch /etc/wsl.conf first. Edit the file with the command sudo nano /etc/wsl.conf and add the following configuration:

# Wsl.conf
[interop]
appendWindowsPath = false

Then restart WSL2 with command wsl --shutdown in Windows(Powershell or CMD).
