ModuleNotFoundError: No module named 'lyrebird.mainwindow'

[TiagoTiago]

I just downloaded V1.0.1, when I try to launch it, I get this:

Traceback (most recent call last):
  File "/usr/local/bin/lyrebird/app.py", line 5, in <module>
    import lyrebird.mainwindow as mainwindow
ModuleNotFoundError: No module named 'lyrebird.mainwindow'

Lemme know what other details you need.

Oh, maybe it's a duplicate: #5 (comment)

edit: Though, that says it started working for them, with me it still borked

What distro are you on and what app launcher are you using? Could you also run ls -la /usr/local/bin/lyrebird for me please?

[TiagoTiago]

What distro are you on and what app launcher are you using?

Linux Mint, with the Mate DE.

I get nothing when I try to run the shortcut, but if I take the command from the shortcut and try to run it on the terminal, I get the error mentioned above.

Could you also run ls -la /usr/local/bin/lyrebird for me please?

$ ls -la /usr/local/bin/lyrebird

I get this message as well when launching it using python3 in a terminal. When using dmenu it just never launches.

I am using Manjaro i3 edition.

ls -la /usr/local/bin/lyrebird output:

Thanks for the info, could you also run:

1. ls -la /usr/local/bin/lyrebird/lyrebird/
2. cat /usr/local/bin/lyrebird/lyrebird/mainwindow.py | head -n 15
3. python3 /usr/local/bin/lyrebird/lyrebird/mainwindow.py

Sorry for all the commands, I'm just trying to figure out if mainwindow.py is installed and well on your system.

This is what I get for reference:

For some reason I am getting a permission denied on the folder /usr/local/bin/lyrebird/lyrebird/

The following allowed it to launch
sudo chown spiffy /usr/local/bin/lyrebird/lyrebird/*

No issues after that.

Most likely a permission issue! I've put in a fix in the latest commit on master. Could you git pull, re-run the installer and check it that solves your issue? From the ls dumps it looks as if you can't access the sources folder.

[TiagoTiago]

I cloned it anew to guarantee a fresh start, and now I'm getting this on the terminal:

Traceback (most recent call last):
  File "/usr/local/bin/lyrebird/app.py", line 5, in <module>
    import lyrebird.mainwindow as mainwindow

    from dataclasses import dataclass

I'll run those commands you asked on a previous reply and come back to post the results.

No need to run what I said before, it looks as if its been solved! Could you find out which Python version you're using by typing python3 --version? My best guess is that your version is out of date.

[TiagoTiago]

$ python3 --version
Python 3.6.9

The Update Manager app is not suggesting any updates though.

[ghost]

Dataclasses are a Python 3.7+ feature, I'm not sure why you're not seeing an update! :-(

[chloecormier]

Linux Mint 19.3 (and Ubuntu 18.04, more generally) comes with Python 3.6.9, TiagoTiago will need to upgrade to Linux Mint 20 to get a version of Python that's new enough sadly :(

[calexil]

sudo apt install python3.7

[chloecormier]

Ah, I wasn't aware it was in the repos as a separate package. That would mean you can run Lyrebird by replacing python3 in the .desktop file with python3.7 specifically (since python3 would still be calling Python 3.6 as the default), but it's a little annoying and unintuitive for new users. It'd be a bit of a bodge but maybe the install.sh script could install a special .desktop file for Ubuntu 18.04 and Linux Mint 19.3 that points to python3.7 instead, and to mention it as a dependency for those versions.
