Re: Import XML fails with python error [Macport LilyPond with Frescobladi]

[Jim Weisbin]

Per the original error message I posted, it was trying to use version 3.8 of 
the Homebrew version. But I tried linking version 3.8, and then version 3.9, 
and even 3.6, still got errors. But in each case, python on the system side had 
no trouble importing encodings.
