Build fails with CleanCommand super()-call

While trying to upgrade the BitBake recipes for python-semver ([Python 2](https://layers.openembedded.org/layerindex/recipe/114255/) and [Python 3](https://layers.openembedded.org/layerindex/recipe/87148/)) from version 2.8.1 to 2.9.1, I've encountered the following error which seems to have been introduced by commit https://github.com/python-semver/python-semver/commit/017e29633562acc8ae9a76c7c8389424263dafd0#diff-2eeaed663bd0d25b7e608891384b7298L39-R39.



Here is the relevant BitBake log for Python 3.7:

 

```

And here is the corresponding log for Python 2.7:



```

```



Looking at the documentation for `super()` in [Python 3](https://docs.python.org/3/library/functions.html#super) and [Python 2](https://docs.python.org/2/library/functions.html#super) makes me wonder if `super(CleanCommand, self).run()` might be a typo and should have been `super(Clean, self).run()`.



Changing `super(CleanCommand, self).run()` to `super(Clean, self).run()` apparently solves the problem for Python 3. For Python 2, the error message stays more or less the same:



```
