Error during the tutorial
Hy everyone,
I am trying to complete the tutorial.
When I type the command:
>launch MY_FIRST_MG5_RUN
I get the following error message:
Command "launch MY_FIRST_MG5_RUN" interrupted with error:
FileNotFoundError : [Errno 2] No such file or directory: '/opt/homebrew/
Please report this bug on https:/
More information is found in 'MG5_debug'.
Please attach this file to your report.
Before that, I ran the command:
>generate p p > t t~
and
>output MY_FIRST_MG5_RUN
with the following output
