Exception generator raised StopIteration

[ghost]

When I launch polymorph command in a python3.7 virtualenv, I get an error loop

Unhandled exception in event loop: File "/usr/pip3/lib/python3.7/site-packages/polymorph/deps/prompt_toolkit/eventloop/coroutine.py", line 90, in step_next new_f = coroutine.throw(exc)

File "/usr/pip3/lib/python3.7/site-packages/polymorph/deps/prompt_toolkit/history.py", line 57, in _start_loading item_callback=add_string))

File "/usr/pip3/lib/python3.7/site-packages/polymorph/deps/prompt_toolkit/eventloop/coroutine.py", line 86, in step_next new_f = coroutine.send(None)

Any solution to fix this ?

Hello jJit0, thanks for the comment. That error has been fixed in the latest version, please try to reinstall polymorph (with pip) or update it.

The thing is I can't update it from pip, because NetfilterQueue can't be installed in python3.7

Failed building wheel for NetfilterQueue

I copied the last version I had from my backup disk

Any idea how to fix that ?

Yes, NetfilterQueue is having problems when installing from pip with python3.7. To solve the problem you can clone the repository (https://github.com/kti/python-netfilterqueue) and run python setup.py install. In this way you should be able to install the dependency.

That's great, it worked for me that way. What I did was :

pip3 install -U git+https://github.com/kti/python-netfilterqueue pip3 install -U polymorph

Thanks again, appreciate it :smile:
