Issue

When entering a new Python REPL after running poetry shell, no typed characters output to the terminal. A REPL instance in Pipenv and with no venv activated do not have this problem. Typed characters are still there, just not echoed:

  ³ .venv  ~/g/test  python                         Tue 03 Dec 2019 04:58:23 PM EST
Python 3.8.0 (default, Dec  3 2019, 11:49:25) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'sdfsdflskdfsdlfk' is not defined
>>> 

However, if I start a new Python REPL after executing poetry shell and paste in import os; os.system('stty sane') and execute it, it returns 0 on the same line and everything functions as expected.

  ³ .venv  ~/g/test  python                  2.6m  Tue 03 Dec 2019 05:01:01 PM EST

>>> 0
>>> Now I see characters!

I do not have this issue on my OSX machine, just my Ubuntu machine.
