> You will notice there are a plethora of extra packages in the virtual
environment that should not normally be there, resulting in a dirty
virtual environment.
Looking at if this can be changed for Ubuntu 20.04. I'm afraid it may be
complex. I think we may need to patch pip to be able to apply these
changes to virtualenv.
> To make matters worse, the latest release of pip bundles incompatible
versions of libraries. The net result is that `pip install pep517` will
show that it is already installed, and but `import pep517` will result
in an ImportError.
I can't reproduce that:
1. pep517 imports successfully.
2. pip can upgrade it, without error.
