Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

[183amir]

I think I modified too much.

@isuruf care to take a look?

I don't feel comfortable reviewing this one. This change is pretty finicky and I don't follow all of the envs and how conda treats them.

Hi! This is the friendly automated conda-forge-linting service.

I was trying to look for recipes to lint for you, but it appears we have a merge conflict. Please try to merge or rebase with the base branch to resolve this conflict.

Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.

@conda-forge-admin, please rerender

[isuruf]

Yeah, I need to check if conda-build respects the condarc in the base environment

[183amir]

It does, we do this already in Bob's CI, https://gitlab.idiap.ch/bob/bob.devtools/-/jobs/247782#L295
