I find nvm in a WSL Linux distro confusing. Firstly, I have nvm for Windows installed. Entering my Ubuntu 20.04 distro and following the install instructions for the Linux version of nvm and then typing whereis nvm, I see the path is a Windows mount at: /mnt/c/Users/seefe/AppData/Roaming/nvm/nvm.exe.
When I printenv in Linux I see
NVM_DIR=/home/seefer/.nvm is pointing at the Linux filesystem version. Very confusing. I also installed gatsby-cli in Windows and Linux and again, it points to the Windows version and typing
gatsby in Linux takes 20 seconds to respond due to slow WSL interop across Windows<->Linux filesystems :/
