Ubuntu on WSL

  1. to access home directory from windows explorer \\wsl$

  2. in ubuntu terminal first cd ~ which will bring me to home for ubuntu... then explorer.exe . which will open up windows explorer at home for ubuntu

  3. Nodemon and webpack-dev-server hot reload not working under WSL 2 after Windows 10 resinstall

I figured this out on my own. Just posting it here in case somebody encounters the same issue. The difference between my system now and before the re-installation is that I upgraded to WSL2. For some reason nodemon and webpack-dev-server hot reload does not work in WSL2. Downgrading to WSL 1 resolved the issue.

EDIT: In order for this to work in WSL 2, the project needs to be inside the linux file system. (I figured it out a long time ago, just forgot to post it here.)

  1. Set Linux Distro Version to WSL 1 or WSL 2 in Windows 10 wsl -l -v wsl --set-version Ubuntu 2

  2. How do I see what packages are installed on Ubuntu Linux?

Reinstalling Ubuntu on WSL

To change wsl distro, run the following commands in Windows Powershell... pref as admin... not sure if it wld work otherwise...

  1. check out the list of basic wsl commands

  2. from the ref above, may want to update to latest version of WSL linux kernel wsl --update

  3. prefer to also set default WSL version to 1 wsl --set-default-version <Version>

  4. unregister old version of distro wsl --unregister <DistributionName> to uninstall. this shld wipe selected distro including all previously installed apps... i.e. shld be clean slate to start over...

  5. wsl --list --online to see a list of available distros and run wsl --install -d <DistroName>, in my case wsl --install -d Ubuntu to install a distro

After Ubuntu installed, can use Windows Terminal window tt opens up Ubuntu terminal

  1. follow instructions frm rocket to ensure Ubuntu has necessary updates/ installations... sudo apt update, sudo apt upgrade, sudo apt install build-essential, sudo apt-get install ca-certificates

  2. lsb_release -a to chk version of Ubuntu installed

  3. to see what has been installed on Ubuntu, run apt list --installed

  4. follow instructions here to install Node.js in Ubuntu together w nvm

  5. to put bck alias to shorten command prompt path... see here on creating a .bash_aliases file to store aliases and here on the command for a shortened command prompt

  6. to edit bash*aliases file in vscode, use code ~/.bash_aliases, cd /mnt/c/Users/boon*/Desktop/rocketacademy/bootcampandPS1="\[\033[38;5;87m\]>\[$(tput sgr0)\]"

  7. reinstall postgresql with rocket instructions here note instructions disabled requirement for password to access databases

  8. Run Multiple Instances of Same Linux Distro on WSL (Windows 10/11)

  9. To install different distros on WSL, just wsl --install -d <DistroName>, to switch between the distros, just wsl -d <DistroName>

Windows Terminal
