Expected Result

I expected the docs to build without error after adding a new doc source file in Sphinx. The environment.yml for conda build was unchanged from yesterday where the docs built correctly.

Actual Result

Doc build is currently failing since it is unable to import yaml. I made no changes to the environment.yml file from the last successful build yesterday.

On a test account, I tried to resolve by adding pyyaml to the environment.yml file with no success.

Was the conda build container changed in the past day or two?

Thanks!

yep -- this is a dupe of #2651, with a bunch of flailing and back and forth :)

@ericholscher Thanks! Sorry, I didn't notice the other issue. Ping me if you want me to test in the morning :-)
