mamba devenv is not using mamba about conda-devenv HOT 4 CLOSED

Thanks @EricAtORS,

For reference mamba support was introduced in #110

from conda-devenv.

Thanks @nicoddemus
I dug a bit more, it looks like mamba devenv is just calling /miniconda3/bin/conda-devenv

from conda-devenv.

This is expected.

conda-devenv should then be calling mamba to update the env.
https://github.com/ESSS/conda-devenv/blob/2.2.0/conda_devenv/devenv.py#L422-L434

The problem is that mamba detection is failing...
As you pointed out, since it calls /miniconda3/bin/conda-devenv that is returned in env_manager = sys.argv[0] causing it to fallback to conda (not mamba) to update the resulting env.
That is indeed not the desired result.

• Now it is possible to use mamba with conda-devenv (#134):
  • Pass --env-manager in the command-line.
  • Set the CONDA_DEVENV_ENV_MANAGER=mamba environment variable.
