Expected Result

Builds worked normally 3 days ago.

Actual Result

Since 2 days ago, the builds always failed with CondaValueError: pip returned an error.

This error happens for other projects using conda, for example https://readthedocs.org/projects/xesmf/builds/7872438/

I noticed the recommendation Use pip when possible. Does this error happen because conda uses too much memory?

I think it can be, I'll test this locally later

@stsewd Thanks! I switched to pip and the error is gone. But does this mean that I shouldn't use conda (also for other projects)?

The just-build page has another problem that the "Edit on GitHub" button is broken. That button was working before. Seems to duplicate #4671. Looks like there's already a solution #4696.

[stsewd]

If your project can be built using pip, that is preferred over conda, if you really need to use conda and it fails, you can request more time/memory for your project. And yes, #4696 fix that problem, hope we can deploy that soon.

Both projects show the same failure:

pip._vendor.pkg_resources.RequirementParseError: Invalid requirement, parse error at "'; extra '"

This doesn't look resource related. Most likely, if not a problem with the formatting of your requirements, is a change in conda somewhere?

[JiaweiZhuang]

@agjohnson Good catch. I think I've found the issue: conda-forge/testpath-feedstock#7

[stsewd]

If this isn't a problem related to rtd, we can close this issue.

Sounds good to me
