Cannot launch Watcher

I try to launch Watcher on my Ubuntu 20.04 and have that issue:

What version of Python are you running? Watcher struggles with 3.8.x...

[PrzemekSkw]

@barbequesauce Hi, thanks for fast answer. I have python 3.8.5. Is there a way to fix that?

[barbequesauce]

It's been a project for several months now - many of our bundled dependencies are incompatible with 3.8 and need to be updated, and there are lots of issues with those updates.

I'm hoping by Christmas...

[PrzemekSkw]

Can You tell me if I use Docker installation on my Ubuntu laptop, it will be OK?

[jandreaucodes]

I installed 3.7.9 to see if I could get Watcher to run again under that, but get the same error.

What's the newest version I can run Watcher3 on, running on macOS?

Edit: I went all the way back to 3.6.12 and am still seeing the same error when I try to launch Watcher3.

Hello, I have the same errors on Python 3.8.5.
There is a way to let Watcher use other my other Python 2.7.10 in another path?
I'm on QNAP.

EDIT: just realized Watcher need Python3 but not 3.8

Thank you!

[barbequesauce]

Latest it will work on currently is 3.7x

[OneCDOnly]

@barbequesauce I'm hoping to get Watcher3 running again for QNAP users running Entware, but a recent package upgrade means we've gone from Python 3.8.5 to 3.9.0. Will your updates work with Python 3.9.0 too?

For future people, I came here because I updated to 20.04 LTS (Ubuntu) and encountered the same issue. To install python3.7:

1. Add PPA:
   sudo add-apt-repository ppa:deadsnakes/ppa
2. Install python3.7:
   sudo apt install python3.7
3. Start Watcher:
   python3.7 ~/Watcher3/watcher.py -p #### -d

@xoniq Thanks, now it works :)

Exactly what I needed... Thanks!

Came here looking for updates...my watcher3 app's not working anymore either.

I'm using a QNAP raid and it has python 3.9 on it.

[barbequesauce]

What version of python are you running? We're currently pinned to 3.7...

[frustin]

3.9, can’t get off it. see (#185 (comment))

+1 from me, I can no longer run W3 either. Please update to support 3.9!
