This tools is a port to the Windows OS from pyenv.
pyenv for Windows is available here: https://github.com/pyenv-win/pyenv-win
From the PowerShell terminal issue the following command:
Invoke-WebRequest -UseBasicParsing -Uri "https://raw.githubusercontent.com/pyenv-win/pyenv-win/master/pyenv-win/install-pyenv-win.ps1" -OutFile "./install-pyenv-win.ps1"; &"./install-pyenv-win.ps1"
And reopen PowerShell.
pyenv install -l
pyenv install <version>
pyenv shell <version>
pyenv global <version>
pyenv local <version>
The tool is analog to the linux tool, see https://telin.ugent.be/telin-docs/linux/python-versions/#list-python-versions
To activate the virtual python environment described in the Linux section, it is now located in the Scripts directory instead of bin:
venv\Scripts\activate
Will bring you in the environment after a python3 -m venv venv command.
