Failure to find matplotlibrc when testing installed distribution #10717

Is the matplotlibrc being correctly bundled / registered for install?

Just a plea - the builds have been failing continuously since I put up this issue. Leaving the builds to fail means it's harder to detect new failures in wheel builds, making it harder to do the eventual release. I am happy to turn off the daily builds if it does not seem worth the effort to support them.
matthew-brett commented on Apr 2, 2018
OK - disabling the daily builds for now.

Does #10929 help with this?

Yep sorry, I wasn't aware that mpl.matplotlib_fname() could actually point to anything other than the shipped matplotlibrc. The file that should be tested is the matplotlibrc.template which resides in the root folder of the source, but after building should be matplotlib\mpl-data\matplotlibrc (without extension). However it seems that this is not always the case?

@QuLogic - thanks for the suggestion - but no - current master (which has #10929 merged I believe) still fails with the same error:

QuLogic commented on Apr 8, 2018
That's not how that line should look with #10929. I think we need a merge up from v2.2.x to master.
QuLogic commented on Apr 10, 2018
Please try again now that v2.2.x is merged into master.

Same failure building mpl commit 0a57153 : https://api.travis-ci.org/v3/job/364856291/log.txt

I built a wheel python3 setup.py bdist_wheel and unzipped it and matplotlib/mpl-data/matplotlibrc was there. So I made a venv and installed it and the file was still there. I'm sorry, but you (or maybe someone on macOS?) will have to investigate this more as I cannot reproduce the problem.
matthew-brett commented on Apr 13, 2018
The OSX installation is standard (and passes all the other tests) (and lots of other projects use it and pass their tests).
Did you try running the tests?

Is this the same issue? Copying matplotlibrc from the install dir got deleted here: 9093edd#diff-c28358ce9623af21f7b6e068f69085b7L725
