Add System Settings

It’s a easy way to use PowerShell here

  1. Adding PYENV, PYENV_HOME and PYENV_ROOT to your Environment Variables

    [System.Environment]::SetEnvironmentVariable('PYENV',$env:USERPROFILE + "\.pyenv\pyenv-win\","User")

[System.Environment]::SetEnvironmentVariable('PYENV_ROOT',$env:USERPROFILE + "\.pyenv\pyenv-win\","User")

[System.Environment]::SetEnvironmentVariable('PYENV_HOME',$env:USERPROFILE + "\.pyenv\pyenv-win\","User")

  2. Now adding the following paths to your USER PATH variable in order to access the pyenv command

    [System.Environment]::SetEnvironmentVariable('path', $env:USERPROFILE + "\.pyenv\pyenv-win\bin;" + $env:USERPROFILE + "\.pyenv\pyenv-win\shims;" + [System.Environment]::GetEnvironmentVariable('path', "User"),"User")

If for some reason you cannot execute PowerShell command(likely on an organization managed device), type “environment variables for you account” in Windows search bar and open Environment Variables dialog. You will need create those 3 new variables in User Variables section(top half). Let’s assume username is my_pc. |Variable|Value| |—|—| |PYENV|C:\Users\my_pc\.pyenv\pyenv-win
|PYENV_HOME|C:\Users\my_pc\.pyenv\pyenv-win
|PYENV_ROOT|C:\Users\my_pc\.pyenv\pyenv-win\

And add two more lines to user variable Path.

C:\Users\my_pc\.pyenv\pyenv-win\bin
C:\Users\my_pc\.pyenv\pyenv-win\shims
