[Matplotlib-users] Failing to install matplotlib with python 3

[Alan]

Hi there,

I am not the admin so I have installed my own python 3.5.1 and I am using
pip3 to install all modules I need. I got all but matplotlib :-(

pip3 install -U matplotlib

                    Collecting matplotlib
  Using cached matplotlib-1.5.1.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-build-6eka4_fr/matplotlib/setup.py", line 167, in
<module>
        result = package.check()
      File "/tmp/pip-build-6eka4_fr/matplotlib/setupext.py", line 980, in
check
        min_version='1.2', version=version)
      File "/tmp/pip-build-6eka4_fr/matplotlib/setupext.py", line 459, in
_check_for_pkg_config
        if (not is_min_version(version, min_version)):
      File "/tmp/pip-build-6eka4_fr/matplotlib/setupext.py", line 179, in
is_min_version
        return found_version >= expected_version
      File "/sw/arch/Test2/lib/python3.5/distutils/version.py", line 70, in
__ge__
        c = self._cmp(other)
      File "/sw/arch/Test2/lib/python3.5/distutils/version.py", line 337,
in _cmp
        if self.version < other.version:
    TypeError: unorderable types: str() < int()

    Edit setup.cfg to change the build options

PS. btw, with python 2.7.11 all went fine.
