New submission from Klaus Ethgen <kl...@ethgen.de>:
I encountered the bug when installing a package with `python3 setup.py install
--user`. After that, a second installation failed with this stack trace:
```
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2191,
in _handle_ns
loader = importer.find_spec(packageName).loader
AttributeError: 'zipimporter' object has no attribute 'find_spec'
During handling of the above exception, another exception occurred:

AttributeError: 'zipimporter' object has no attribute 'find_spec'
```
This error happens now also with different tools.
Solution is to `rm -fr ~/.local/lib`. But the next installation triggers the
bug again.
The only solution is to install via `python3 setup.py install --user
--old-and-unmanageable`.
When I look into the code of zipimport(er), I do not see any find_spec only the
old find_loader.
Despite it is a core library, this must be fixed! And with that the name should
match the name of the py file to make it able to find the relevant file.
