hangups macOS 10.13.5 / Python 3.7

[psonis]

I get this error when trying to run it on my Mac:

Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.7/bin/hangups", line 7, in
from hangups.ui.main import main

self._listen_future = asyncio.async(self._channel.listen())
^
SyntaxError: invalid syntax

Any clues?

[psonis]

I commented line 135 in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/hangups/client.py and it worked...
self._listen_future = asyncio.async(self._channel.listen())

But now I get Login failed (Authorization code cookie not found) when I enter my credentials.
I am using a unique app password because I have 2FA enabled.

I managed to log in but now I got a number of errors

Probably shouldn't have commented the line in the first place...

[psonis]

OK reverted to Python 3.6.x
I guess 3.7 isn't fully compatible...

[Terrance]

Deleting arbitrary lines likely won't get you very far...

Regarding the original error: async is a reserved keyword as of 3.7, and asyncio.async (deprecated since Python 3.4) was removed as a result -- this and other instances needs updating to use asyncio.ensure_future instead (hangups requires 3.5+ so this shouldn't be an issue).

3.7 hasn't yet landed on Arch so I've yet to test it, not sure if there are any other breaking changes.

[psonis]

Yes you're right.
I do get occasionally crashes with Python 3.6.6 (v3.6.6:4cf1f54eb7) and macOS 10.13.5.
Here is the traceback:

I just released 0.4.5 which supports Python 3.7.

[psonis]

I just re-installed 3.7 and 0.4.5 but I get this error after logging...

There's a report here that installing openssl fixed that: #181 (comment)

[psonis]

Well, macOS openssl was the culprit.
I removed the "official" Python 3.7 and installed this one
brew install python --with-brewed-openssl
and it worked.

BUT...
after using it for 10-15 minutes, it crashed :(
Here's the traceback:
