pip fails to detect and install matplotlib dependencies

[vbabiy]

Running pip 0.6.3 with Python 2.6 on Ubuntu 9.10 x64

Executing "pip -E . install matplotlib" fails on its own.

However, executing a "pip -E . install numpy" followed by "pip -E . install matplotlib" allows both installs to continue just fine.

Traceback attached.

Running pip 0.6.3 with Python 2.5 on Ubuntu 8.04 x64 also produces the same
problem.

After entering virtualenv, "pip install -r my-list.txt" said it requires numpy
and failed.

$ virtualenv --no-site-packages tmp

$ source tmp/bin/activate

$ echo "matplotlib" > my-list.txt

$ echo "numpy==1.3.0" >> my-list.txt

$ pip install -r my-list.txt

...

(error, see the attachment for full message)

But use pip install numpy first would work.

In my opinion this is really a problem with matplotlib and the way its setup.py file is written.

indeed, the setup() call in matplotlib's setup script has no install_requires or extras_require parameters. i think it's safe to call this a bug in matplotlib. its setup script still refers to distutils, which (to my knowledge) doesn't support these parameters. unfortunately, the project's website refers to a sf.net bug tracker that is disabled. i sent a message to the matplotlib-users list detailing this problem. i'll post an update here once it's resolved.
