Error while burning bootloader

I bought it to use the weather kit, but I’m having trouble uploading it due to an error. Help me!

There was a new python release for Mac a few days ago that I think fixes some similar errors - try updating and report back?

If it gets too frustrating, I usually find that completely wiping the Arduino IDE and starting over works MOST of the time (you have to delete the arduino15 folder too!)

Finally, you might need to update the IDE to the Beta version (2.0)
