Issue 20809: isabspath receiving path value of None in distutils.dist.py (original) (raw)

So far I've noticed this is only reproducible when running quickly with python2.7. Still, the error message seems like it would be confusing to new users to Python.

The particular error you see is caused by code in the setup.py file of the project you are installing. I suggest you figure out what's going on there:

File "setup.py", line 116, in run target_data = '/' + os.path.relpath(self.install_data, self.root) + '/'
