readthedocs.org: Problems with project virtualenvs

Details

I am getting the following error on readthedocs when I try to manually build docs or when a build is triggered by a push to the GitHub repo:

 New python executable in /home/docs/checkouts/readthedocs.org/user_builds/clustergrammer/envs/latest/bin/python2.7
Traceback (most recent call last):

IOError: [Errno 40] Too many levels of symbolic links: '/home/docs/checkouts/readthedocs.org/user_builds/clustergrammer/envs/latest/bin/python2.7'

The builds seemed to spontaneously stop working and reverting to old versions of docs that previously worked does not help. I am running

sphinx-autobuild . _build_html to build the docs.

Project URL: http://clustergrammer.readthedocs.io/en/latest/
Build URL (if applicable): https://github.com/MaayanLab/clustergrammer/tree/master/docs
Read the Docs username (if applicable): corrnhundred

Expected Result

I modified the documentation, successfully built with sphinx-autobuild, pushed to GitHub, but the build (automatic web hook) failed on readthedocs’ site. A description of what you wanted to happen Documents to build on readthedocs’ site

Actual Result

Build fail. A description of what actually happened

This is a problem on our side, from upgraded build images. Not sure exactly what causes this scenario though, but perhaps it’s a slight difference in the installed Python version between the two images.

I also tried re-building the docs from scratch using:

sphinx-quickstart

and deleting/remaking the project on readthedocs.io, but I am still getting the same error.

I also tried moving my docs to a new repo and building with the same project name, but this failed.

However, I am able to build using the same documentation (in a new repo) with a different project name

http://clustergrammer-docs.readthedocs.io/en/latest/.

So, I think the error is somehow tied to the url/project-name

http://clustergrammer.readthedocs.io/en/latest/

since I cannot get anything to build using that name, but I can get the same docs to build using another project name on readthedocs.io.

Also failed for me with the same error. My project is tensorpack.
