I am a ruby programmer trying to learn python. I am pretty familiar with pyenv since it is like a copy and paste from rbenv. Pyenv helps allow to have more than one version of python in a system and also to isolate the python without touching sensitive parts of system.
I suppose every python installation comes with pip package. What I still don’t understand is, there are many good python libs out there that suggest to use this virtualenv and anaconda. I can even find a virtualenv plugin for pyenv.
Now I am getting confused with the purpose of these two pyenv and virtualenv.
worse inside pyenv there is a virtualenv plugin.
My questions are:
- what is the difference between pyenv and virtualenv?
- Is there any difference in using pip command inside both pyenv and virtualenv?
- what does this pyenv virutalenv do?
Your explanation with example will be highly appreciated.
