I got a .ly file claiming to be version 2.18.0 and opened it in LP
version 2.22.0-1. When I did “Update syntax” I got these errors, and
the version in the file did not change.
[Image showing AttributeError: 'file' object has no attribute 'detach'
I can typeset the file with no problems.
I thought you should know.
Hello,
This is a serious problem. The error indicates that
Python 2 is being used. The scripts were ported to
Python 3 in release 2.22. What is your OS? How are
you running convert-ly? Does it reproduce in a terminal?
(Try running 'convert-ly myfile.ly' there.)
Eventually this should be made a bug report to the
bug-lilypond list (see lilypond.org/contact.html).
Best,
Jean
