Broken on windows

[Antoine Dechaume]

Hello,

the latest release and the master branch do not work for windows 10 (I've not tested other windows versions).
For instance, see what happens when using tox-conda with its own sources:

• setup with

conda create -n tox-conda python=3.8 pip
conda activate tox-conda
pip install -e .

• The executable installed in an env and used by a command is not found, here pre-commit

tox -e fix_lint
    fix_lint create: C:\Users\AntoineD\PycharmProjects\tox-conda\.tox\fix_lint
    fix_lint installdeps: virtualenv < 20.0.34, pre-commit >= 1.14.4, < 2

• And here pytest, found outside the env

Also, the interpreter installed inside an anaconda env is not recorded by tox (in envdir/.tox-config1) the first time an env is created, then on the second run of an env tox cannot reuse it and thus recreates the env. This happens on all platforms.

I will propose a PR for these issues.

Closing since it is fixed in master.

[Bernát Gábor]

Version 0.3.0 just released contains this.

[Antoine Dechaume]

Thanks a lot @gaborbernat.
BTW, I'm working on a fix for #19.
