Problem during compilation

[benoitgoyet]

Hi,

I had to reset my computer. And I can(t succeed on compiling using mbed cli.
It used to work before reset, but not any more...

I get the following error message :

[mbed] Working path "/Users/goyetbenoit/Documents/10_PROGRAMATION/troporteur" (program)

Tip: You could retry the last command with "-v" flag for verbose output

Does anyone has some idea?
Thanks.

The issue is related to python 3.9 and does already effect some other projects for example: tensorflow/tensorflow#45164, home-assistant/core#41617.
It's an already fixed bug in intelhex (python-intelhex/intelhex#45), updating the dependency should fix the problem. (It also can be used as workaround for the issue)

@benoitgoyet I'm not allowed to update the issue, could you please update the title to something like Python 3.9 Issue with old intelhex version?
