Re: [Matplotlib-users] Installation issue: python setup.py install --home=... fails

When you use |--home|, distutils assumes you are referring to a home directory in which you have a tree of libraries in |lib|lib64| living there, so it appends |lib64/python| to the given path: |> python setup.py install --home=/foo running install Checking .pth file supportin /foo/lib64/python/ error: can't create or remove files in install directory| So the issue is not that your PYTHONPATH doesn't contain |/lsst/home/rowen/code/sandbox/Linux64/external/matplotlib/1.3.1+1| (which it does) but that it doesn't contain |/lsst/home/rowen/code/sandbox/Linux64/external/matplotlib/1.3.1+1/lib/python|. With matplotlib 1.2.1, we used raw distutils and not setuptools, which does the same thing without the strict check. And that does allow users to shoot themselves in the foot, since the check is in fact right when it says things won't work: |> git checkout v1.2.1 > mkdir ~/foo > python setup.py install --home=~/foo ... > PYTHONPATH=~/foo python Python2.7.5 (default, Oct8 2013,12:19:40) [GCC4.8.1 20130603 (Red Hat4.8.1-1)] on linux2 Type"help","copyright","credits" or "license" for more information. >>>import matplotlib Traceback (most recent call last): File"<stdin>", line1,in <module> ImportError: No module named matplotlib| I think what you really want to use is |--install-lib|, which will install the matplotlib library directly inside of the given path, which (if it's also on the `PYTHONPATH`) it will work.
