Mu Editor crash

by csva on Thu May 28, 2020 10:06 pm

I installed Mu-Editor, it crashes when I click the "Adafruit CircuitPython" from the options, but not the others.

Starting from a terminal it crashes.

(Logging to /home/user/snap/mu-editor/common/.cache/mu/log/mu.log)

Some kind of Python permission issue? The "execute_child" is kinda harsh.

(I also saw this on ... _crashing/ )

It does seem like a permission error, though I'm not aware of how to fix it. I would suggest reviewing the official Mu documentation's installation instructions, and if that doesn't help try asking for suggestions on the chat system linked from their discussion page:

I'm experiencing the same issue. I'm wondering if anyone found a solution. If so, can you point me in that direction?
