Can confirm this on 3.8.0rc1+ / macOS Mojave:
```console
$ python -c "import importlib.metadata;
print(list(importlib.metadata.distributions()))"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File
"/Users/florimond/.pyenv/versions/3.8-dev/lib/python3.8/importlib/metadata/__init__.py",
line 175, in <genexpr>
resolver()
File "<frozen importlib._bootstrap_external>", line 1381, in
find_distributions
ImportError: cannot import name 'MetadataPathFinder' from 'importlib.metadata'
(/Users/florimond/.pyenv/versions/3.8-dev/lib/python3.8/importlib/metadata/__init__.py)
```
I discovered this pytest started failing on 3.8-dev because it uses
`importlib.metadata.distributions()` internally.
3.8.0b4+ used to be fine I believe. I'd assume this is a rather critical bug?
