Actual Result

Getting an exception during the command:

$ python -mvirtualenv $READTHEDOCS_VIRTUALENV_PATH

Error:

Looks to me like READTHEDOCS_VIRTUALENV_PATH isn't set for some reason.

This is because build.tools.python is not set to mamba or conda. Read the docs about this config and set it properly and your build will work.

(I'm on the phone 📱 now)

Changed config to this:

build:
  os: ubuntu-22.04
  tools:
    python: "miniconda3-4.7"

The build succeeded. Would be nice to get an error message if conda config keys are set together with an explicit python version.

Thanks for the help.

Yes, we have a few issues about improving these error messages. We weren't able to prioritize then yet.
