Running ipython fails with `No module named 'pexpect'`
Hi, this project looks very interesting, thanks for working on it!
I tried to install jupyter & run the ipython CLI, but got this error:

ModuleNotFoundError: No module named 'pexpect'
Running pyflow install --dev pexpect fixes it, but this is a bit surprising, since a similar set of install commands works fine with virtualenv:
$ python -m venv virtualenv
$ source virtualenv/bin/activate
(virtualenv) $ pip install --upgrade pip
(virtualenv) $ pip install jupyter
(virtualenv) $ ipython
Full output for these commands
$ python -m venv virtualenv
$ source virtualenv/bin/activate
(virtualenv) $ pip install --upgrade pip

I am getting this error as well. Maybe a problem with dependency graph generator? If I run pyflow install pexpect then try to initiate ipython it runs.
After pyflow install ipython followed by pyflow install pexpect I now get this error on Ubuntu 20.04:

I've got the sqlite dev libraries install, I wonder if there is a way to install the right version of python?
