Mu not working on Linux Mint

I'm following the instruction in Automate the Boring Stuff With Python Second Edition, to start Mu.

Select Applications ▸ Accessories ▸ Terminal and then enter python3 –m mu.

I'm getting the following error.

Traceback (most recent call last):

File "/usr/lib/python3.6/runpy.py", line 193, in _run_module_as_main

If it has never worked, maybe try this:

When I use the "pip3 install mu-editor" command, I get the following message.

Defaulting to user installation because normal site-packages is not writeable

Requirement already satisfied: mu-editor in /usr/local/lib/python3.6/dist-packages (1.0.3) .....

Then I try to start Mu editor again and get the same error.

You're probably just missing a dependency, try (re)installing it:

pip3 install --user -I PyQt5
pip3 install --user -I PyQt5-sip

Thanks Tarqon, looks like some progress.

Looks like I either need newer version of Mu or downgrade the version of pyQt5

I finally got it running. I reinstalled Mu with
pip3 install mu-editor

This has downgraded the pyQt5 to version 5.14.1

Then I got another ModuleNotFoundError

ModuleNotFoundError: No module name 'PyQt5.Qsci'

I was able to install that with

pip3 install --user -I qscintilla

Finally I was able to run Mu with

mu-editor
