Details

One of the dependencies in my doc/requirements.txt is failing to install with error

The same configuration used to work until yesterday. Can someone help? Any pointer will be appreciated.

The dependency (pyspark) uses setup.py, so setuptools is required.

• Read the Docs username (if applicable): https://readthedocs.org/profiles/chohyu01/

Expected Result

The build should be able to install dependencies successfully.

Actual Result

One dependency, pyspark, fails to install due to setuptools not available.

Hi, I can see in your build that we are installing the latest version of setuptools and then installing an old version, #10287 should fix this.

@stsewd Thank you!

Thanks for the fix @stsewd! What's the typical release cycle for bug fixes like this?

if it's the next day or so, I can hold off merging some pull requests that depend on documentation being built, if it's a week or so out, I'll work out a temporary solution to check if documentation builds successfully.

Thank you.

@jdkent we usually deploy on Tuesdays.
