Я использую Windows10:
PS C:\Users\hp\Documents\Projects> pip install pip --target $HOME\\.pyenv
pyenv успешно установлен.
PS C:\Users\hp\Documents\Projects> pyenv
The term 'pyenv' is not recognized as a name of a cmdlet, function, script file, or executable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
