installing Python packages on SLES doesn't work out of the box #373

@ocaisa, @pforai: Can you provide the details of this problem that was reported during today's EasyBuild conf call?

ocaisa commented 10 years ago

I remember now that I had to do this on Juropa, which is OpenSUSE. You need a special file in your home directory:

ocaisa@jj28l05:~> more .pydistutils.cfg [install] prefix=

Without this you can't install python modules in user space, it always tries to go back to the system default.

On SLES, the site package location is customised to /usr/local/lib64/python2.6/site-packages with the file /usr/lib64/python2.6/distutils/distutils.cfg. And this file has the following stanzas in there:

[build_py]
optimize=0

[install]
prefix=/usr/local
optimize=0

Now the issue is that the prefix specified in there is global (ie for every user) and easy_install and pip (distribute) generally will read this file and even if the appropriate options are used for installation (like pip install --user) that global setting has higher priority and is still in effect.

As such users on SLES systems will not be able to install EB with pip or easy_install. Also installation of python packages with EB (which is using --prefix for calls to setup.py) will fail as normal system users don't have permissions in /usr/local.

We have the following configuration in $HOME/.pydistutils.cfg 

[install] 
prefix=

to solve this issue.
