Installation issue

[yiyangshi]

Tried to install the project on Linux system with Python 2.7.

According to the instruction, I first did: sudo apt-get install python-matplotlib
And tried to test it:
$ python

import matplotlib
matplotlib.test()

Then I got error:

ERROR: Failure: IOError (The baseline image directory does not exist. This is most likely because the test data is not installed. You may need to install matplotlib from source to get the test data.)

Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/nose/loader.py", line 400, in loadTestsFromName
module = resolve_name(addr.module)
File "/usr/lib/python2.7/dist-packages/nose/util.py", line 311, in resolve_name
module = import('.'.join(parts_copy))
File "/usr/lib/pymodules/python2.7/matplotlib/tests/init.py", line 17, in
'The baseline image directory does not exist. '
IOError: The baseline image directory does not exist. This is most likely because the test data is not installed. You may need to install matplotlib from source to get the test data.

So I tried to install from source following the instruction in INSTALL file. I downloaded the source from https://pypi.python.org/pypi/matplotlib/
And did:
$ cd matplotlib-1.5.1
$ python setup.py build
$ sudo python setup.py install

All the commanded succeeded. But when I run matplotlib.test() again. I got the new error:

Traceback (most recent call last):
File "", line 1, in
File "/usr/local/lib/python2.7/dist-packages/matplotlib-1.5.1-py2.7-linux-x86_64.egg/matplotlib/init.py", line 1504, in test

I also tried to install on Python 3：
$ sudo apt-get install python3-matplotlib

import matplotlib
matplotlib.test()

ERROR: Failure: OSError (The baseline image directory does not exist. This is most likely because the test data is not installed. You may need to install matplotlib from source to get the test data.)

Traceback (most recent call last):

OSError: The baseline image directory does not exist. This is most likely because the test data is not installed. You may need to install matplotlib from source to get the test data.

So again I tried to install from source.
$ python3 setup.py build

but I got this error:

The final error is most likely due to not having the python3 development
libraries installed.

As for the other errors, it depends on how you obtained the source. Was it
from the tar.gz available on github? Was it through git clone? What source
package did you use? We started to stop including the baseline images in
the releases to shrink down the size.

The next-to-last error is just saying that you need to install nose for the test.
I don't think this issue needs to stay open. For advice and troubleshooting of various installation methods, the matplotlib-users mailing list is a better forum.
If you just want to use matplotlib, your initial installation with apt-get was probably fine.
