I am not allowed to install anaconda on my enterprise machine, so I decided to use pyenv to manage virtual environments. I am following this tutorial to get my hands on pyenv. I think that my issue is close to what represented here.

At this time I have windows powershell open as administrator. When I do:

pyenv versions

I will get:

enter image description here

And when I do:

ls $PYENV_ROOT/versions/

I will get:

enter image description here

Impossible to find path to "C:\versions", cause it does not exist.

Also when I do:

pyenv version

I will get: enter image description here

Another strange observation is that when I open another powershell (or CMD) window without administrative right and call pyenv, It does not recognize it.

  • Have you tried to set global version with pyenv global <version-number-you-want>? Commented Nov 17 at 11:03
  • I just did that. Asterix apears next to the globaly-set python version but still "ls $PYENV_ROOT/versions/" can not find the path. It seems to me that I have to manually set some path! Commented Nov 17 at 11:40

  'Path',
  $env:USERPROFILE + "\.pyenv\pyenv-win\bin;" +
