Docs build hitting an ImportError - any guesses?

The Launchpad daily builds have recently started failing on the docs build. I get the error message “Error: matplotlib must be installed before building the documentation”, which means that there’s an ImportError raised when it tries to import matplotlib. Unfortunately, it hides any other information about the ImportError, and I can’t currently replicate it on my own computer.

It builds the Python library, then attempts to build the docs with the command:

cd doc ; MATPLOTLIBDATA=…/lib/matplotlib/mpl-data/
PYTHONPATH=…/build/lib.linux-i686-2.7 ./make.py --small all

Does anyone know what might have changed a few days ago to cause this? It built successfully on the 26th of February, there was a different problem on the 27th, and when I resolved that, this failure started on the 28th. I’ve had a look at the commit log, but nothing jumps out.

Thanks,

Thomas

Nothing springs to mind. Perhaps the install is failing due to https://github.com/matplotlib/matplotlib/pull/1454?

Sounds like you don’t have access to the machine to check that

$> python -c “import matplotlib”

Works?
