tox should run for all environments #2

In tox.ini there is an envlist

envlist = py27, py35, py36, py37, py38, py39, py310, pypy, pypy3 #, jython

From that list first jython stopped working, then many other interpreters for various reasons unrelated to Lena. For example:

IOError: [Errno 13] Permission denied: '/home/.../lena/.tox/pypy3/lib/pypy3.8/site-packages/_virtualenv.pth'

or

    ImportError: libffi.so.7: cannot open shared object file: No such file or directory

I installed pypy3 packages manually and my tests worked. Can it be fixed for all interpreters from the list? (volunteers needed)
