First of all, please be aware of
<https://trac.macports.org/wiki/FAQ#prerelease>.
Sorry for bugging the mailing list with a day-one beta.
Trying to run macports with 'sudo port’ errors out with a OS platform mismatch
error.
Error: Current platform "darwin 21" does not match expected platform "darwin 20"
Error: If you upgraded your OS, please follow the migration instructions:
https://trac.macports.org/wiki/Migration
OS platform mismatch
while executing
"mportinit ui_options global_options global_variations"
Error: /opt/local/bin/port: Failed to initialize MacPorts, OS platform mismatch
Is there a workaround to use MacPorts (knowing that it’s unsupported and data
loss might happen)
before any official support comes out?
The solution is in the error message: you upgraded to a new OS version,
so you need to follow the Migration instructions. Since there is
obviously no binary installer for this OS version, step 2 "install the
base MacPorts system for your new platform" will need to be done by
installing from source.
