cannot import name 'sealed_sender' from 'signal_protocol'

[eloquence]

In spite of installing the updated version in requirements.txt (per #1), I am getting

Traceback (most recent call last):
  File "journalist.py", line 9, in <module>
    from signal_protocol import address, curve, identity_key, storage, sealed_sender, session, session_cipher, state, protocol
ImportError: cannot import name 'sealed_sender' from 'signal_protocol' (/home/erik/.virtualenvs/e2e/lib/python3.7/site-packages/signal_protocol/__init__.py)

when attempting to run journalist.py per the README. I installed signal-protocol in a virtualenv via pip install -r requirements.txt:

$ pip install -r requirements.txt 
Requirement already satisfied: signal-protocol==0.2.2 in /home/erik/.virtualenvs/e2e/lib/python3.7/site-packages (from -r requirements.txt (line 1)) (0.2.2)
Requirement already satisfied: signal-groups==0.1.0 in /home/erik/.virtualenvs/e2e/lib/python3.7/site-packages (from -r requirements.txt (line 2)) (0.1.0)

this is definitely due to sealed_sender being added in 0.2.2 since the other submodules are getting imported. Can you try blowing away your virtualenv and recreating? (I'm currently not sure why that would be happening... 🤔 )

Another idea if that doesn't work is to try installing with the option --no-cache-dir (such that pip's cache is not used)

Still no dice, here's what I'm doing (this is a brand new venv):

I think there may be an issue with the wheel you are using on Linux only, try building on latest main: (f3cf8422563dc66b06c70d5f52a4145370c9756a) which should use the regular manylinux wheel

That did indeed resolve, thanks! :)
