If you use a virtualenv (google for instructions if you're not
familiar), you can have all the versions be what they need to be for
this install, without impacting your system versions of things - that's
about the only advice from here. Although, I tried to install pygit2 in
a virtualenv and it failed, though a bit of a different error, so it may
be the pygit2 project itself is having some issues getting their
dependencies right.
I got this:
raise DistutilsError("Setup script exited with %s" % (v.args[0],))
distutils.errors.DistutilsError: Setup script exited with error:
command 'gcc' failed with exit status 1
without any hint of *why* gcc failed, probably it was a missing C header
file but haven't researched.
