It's safe to use either, but setuptools considers '-' to be canonical; this
was a heuristic decision on my part because '-' appears more frequently
used than '_' in the names of projects currently registered with PyPI.
The problem, however, is that PyPI wants your uploaded files to *exactly*
match the registered name. If you used '-' in setup.py, you must have '-'
in the filename, and that's something setuptools cannot do. It would
probably be best if setuptools ensured the "register" command always used
'_', but then this defeats the purpose of having it that way in the first
So, the only real fix is to change PyPI to accept files whose
pkg_resources.safe_name() match the safe_name() of the project. In the
meantime, you can't upload eggs to PyPI for packages with '-' or '_' in
their names. (You can upload source distros or other formats, since those
can work with ambiguous filenames.) I probably should put in an RFE or
proposed patch, but I've been *really* busy lately.
