Discussion: Add runtime warning if people mix defaults and conda-forge

Open jonashaag opened this issue 1 year ago • 4 comments

I've gone out of my way to help people avoid the "mixing defaults and conda-forge channels":

  • https://github.com/mamba-org/mamba/pull/2181
  • https://github.com/mamba-org/mamba/pull/2451
  • https://github.com/mamba-org/mamba/pull/2569
  • https://github.com/mamba-org/mamba/pull/2619
  • https://github.com/mamba-org/mamba/pull/2809
  • https://github.com/mamba-org/mamba/pull/2904
  • https://github.com/mamba-org/mamba/pull/2908
  • https://github.com/mamba-org/mamba/pull/2996

Still people make that mistake.

I propose to add a runtime warning to Mamba, or have Mamba outright refuse to work, when the channels are mixed.

Just to be clear, you are talking about the Anaconda default channels NOT using conda-forge AS your default?

Please rephrase the question I don't understand

You appear to be using the word "defaults" to refer specifically to the Anaconda default channels NOT to the concept of a default conda channel which could be configured to point elsewhere. I configure my conda defaults to point at conda-forge but still have some scripts that add -c conda-forge and it doesn't seem to cause problems.

Yeah it's fine to use non-Anaconda defaults channels, although I don't recommend it because it makes environment.yml files less well specified when you don't include the channels
