Install WSL and Linux Distro for Windows Machine

If you are using Linux based system skip these steps for installing wsl & Ubuntu

1. First you need to Make sure your Windows version is at least Windows 10, version 2004. You can check your Windows version by going to Settings > System > About.

2. Open PowerShell as an administrator and run the following command to enable the WSL feature:

  Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

3. Restart your computer when prompted.

4. You can now install everything you need to run WSL with a single command. Open PowerShell or Windows Command Prompt in administrator mode by right-clicking and selecting Run as administrator

wsl --install

5. Then restart your computer.

6. To install Ubuntu-20.04 use the following command in powershell or command prompt then restart

wsl --install Ubuntu-20.04

7. If you want to install additional distributions from inside a Linux/Bash command line (rather than from PowerShell or Command Prompt), you must use .exe in the command:

wsl.exe --install -d <Distribution Name>

8. You can list your installed Linux distributions and check the version of WSL each is set to by entering the command in PowerShell or Windows Command Prompt:

wsl -l -v

9. To set the default version WSL 2 when a new Linux distribution is installed, use the command:

wsl --set-default-version 2

10. To set the default Linux distribution used with the wsl command, enter:

wsl -s <DistributionName>

or

wsl --setdefault <DistributionName>

replacing <DistributionName> with the name of the Linux distribution you would like to use.

Install python 3.10 in WSL Ubuntu

To install Python 3 in WSL Ubuntu, follow these steps:

1. Open the terminal in WSL Ubuntu.

2. To update the package list run the following command

3. To install Python 3 run the command

sudo apt-get install python3 

4. Verify the installation by running the command and it should display the version of Python 3 that you have installed.

python3 --version

5. If you want to install pip for Python 3, run the command

sudo apt-get install python3-pip

6. Verify the installation by running the command and it should display the version of pip that you have installed.

pip3 --version

7. You now have Python 3 and pip installed in WSL Ubuntu. You can now use Python 3 to write and run your programs.

Install pyenv

1. Open the terminal in WSL Ubuntu.

2. To update the package list Run the command

sudo apt-get update

3. To install the necessary dependencies for pyenv run the command

sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl

4. to install pyenv run the command

curl https://pyenv.run | bash

5. Add the following lines to your .bashrc file:

export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

6. To apply the changes run the command
