pip-compile and Python 3.11?

[David Johansen]

I've been using pip-compile and I'm trying to upgrade to Python 3.11 with reportlab and rlextra, but it's running into an error. I'm assuming it's because rlextra isn't available for Python 3.11 and pip-compile isn't handling that well, but is there a way to fix this or workaround it?

Here's the traceback from the error:
