ImportError with setuptools 50.1.0

Hello,

paste's setup.py is not working with the latest version of setuptools 50.1+. I am getting this error:

Traceback (most recent call last):

ImportError: cannot import name 'escape' from partially initialized module 'html' (most likely due to a circular import) (/builddir/build/BUILD/Paste-3.4.0/paste/util/html.py)

Problem is that setuptools started to use the standard library html module which name-conflicts with paste.util.html. Paste's setup.py inserts paste/util tosys.path:

https://github.com/cdent/paste/blob/3.4.0/setup.py#L19

And hence setuptools, when importing html, imports paste/util/html.py which tries to import html as well, imports paste/util/html.py...

I would suggest to delete paste/util from sys.path after importing finddata. This way setuptools will use the correct html module (or any other name-clashing module).

Have a nice day, Tomas
