[Pysparse-users] Pysparse installation problems

[Rob S. <rs...@MI...>]

I'm having two problems that make it difficult to install Pysparse in
many situations. I'm writing a library that depends on Pysparse, but I
can't distribute this library if Pysparse itself won't install.


1. Pysparse doesn't support "setup.py develop". This means it cannot
be installed through Pip.

This seems to be because of the line:
   package_dir = {package_name: 'Lib'},

The problem is that there is no valid directory to put on the Python
path. Here's a bug report about this issue (which was closed as
invalid in Pip because they concluded it's a problem with either
setuptools or pysparse):

http://bitbucket.org/ianb/pip/issue/72/editable-install-doesnt-respect-package_dir

It sounds like this could be fixed by reorganizing the code structure,
or at least making a symlink, so that there is an actual "pysparse"
directory at the top level. Renaming "Lib" to "pysparse" might be the
right answer.


2. Pysparse won't install in a virtualenv. It tries to install files
in the include/ directory of your Python environment, but virtualenvs
don't have their own include directory. They just symlink to the
system-wide one.

I don't know what the correct way to resolve this one is, because I've
never had to manage additional include files in a Python package.

Thanks,
