Poetry: potry does not install python

[magnusja]

• [X] I am on the latest Poetry version.
• [X] I have searched the issues of this repo and believe that this is not a duplicate.
• [X] If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: ArchLinux
• Poetry version: 0.12.11
• Link of a Gist with the contents of your pyproject.toml file: not important I believe

Issue

$ poetry install -vvvvv

Why isn't poetry just fetching a compatible python version, installing it locallz and then installing dependencies instead of forcing me to handle this?

[itsthejoker]

That's not what poetry is for. Use pyenv, pacman, or compile it yourself to install the appropriate python version.

Ok I see, would be quite handy though imho.

Would it be possible to make pyenv available to poetry, so that it finds all available versions and picks the correct one?
