Pyenv-virtualenv: Conda 4.4.4 breaks pyenv virtual environments

[melentye]

How to reproduce

• pyenv install miniconda3-latest (the result is actually the same with miniconda3-4.3.3 since conda gets updated to 4.4.4 during the install)
• pyenv virtualenv miniconda3-latest my-env

After performing the above steps, pyenv which conda doesn't list my-env as one of the environments that have the executable, it's missing in ~/.pyenv/versions/miniconda3-latest/envs/my-env/bin/ and upon the environment's activation with pyenv activate my-env, conda command is not available.

Workaround

After installing miniconda3-latest, downgrade conda to 4.3.30:

• pyenv activate miniconda3-latest
• conda install conda=4.3.30
• re-create the affected virtual environments

Just speculating here, but the issue may be caused by https://www.anaconda.com/blog/developer-blog/how-to-get-ready-for-the-release-of-conda-4-4/ in Conda 4.4.4, for example the name of the default environment has been changed from "root" to "base".

Thank you for the temporary workaround. I ran into this issue earlier today when upgrading my miniconda versions.

More reports for this issue are also present in #178

I have the same problem here.

290 was recently merged.

Does the issue persist?

I can now access the conda environment through pyenv activate myenv, but pyenv which conda points to the root conda version rather than the conda environment's bin directory.

I think the root conda executable serves all environments now.
In my tests with the latest conda release and pyenv removed, conda create -n test doesn't even create a bin directory, so that appears to be the new design.

Do your conda environments work with pyenv?
Can you

• pyenv versions
• pyenv virtualenvs
• pyenv local version
• pyenv virtualenv root-conda new-version
• pyenv virtualenv-delete version

with conda environments?

[clbarnes]

Just checked: all of those work. It just surprised me that the conda binary in the root environment would install packages in my activated environment rather than the root one.
