Crashes with AttributeError: 'TestenvConfig' object has no attribute 'conda_exe'

[SimonBin]

If tox and tox-conda are installed,

this config

[tox]
requires = tox-conda
           tox-run-before

I have this same problem, downgrading to ~=0.7.0 should fix this

[SimonBin]

setup.py and tox.ini as yours

conda create --name toxcondabug python=3.8
conda activate toxcondabug
conda install tox-conda -c conda-forge
tox

(error appears)

[AntoineD]

Thank you, I can reproduce it now.

[AntoineD]

Meanwhile, just install tox (no tox-conda) in your anaconda environment:

conda create -c conda-forge -n toxcondabug python=3.8 tox
...

conda run -n toxcondabug --no-capture-output tox  
.tox create: /tmp/0/.tox/.tox

I have the same issue that is triggered when I try to specify a pip version:

[tox]
requires =
    tox-conda
    setuptools >= 40.8.0
    pip < 22

Not setting pip in the requires list or removing tox-conda from the environment fixes the issue.

I also note that the pip version set in requires is not respected.

> conda list
  # packages in environment at E:\Programming\Python\git\taxonopy\.tox\py37:
  #
  # Name                    Version                   Build  Channel

[AntoineD]

I think that requires refers to the packages installed in the provisional environment from where tox is executed from, and not to the environments from where the commands are executed.
@gaborbernat Is it correct?
