Summary: cqlsh - module 're' has no attribute 'sre_parse' - with
Python 3.11
Key: CASSANDRA-18088
URL: https://issues.apache.org/jira/browse/CASSANDRA-18088
Project: Cassandra
Issue Type: Bug
Reporter: Aaron Ploetz
User reported an error with cqlsh (Cassandra 4.0.7) on Stack Overflow:
[https://stackoverflow.com/questions/74673247/cannot-able-to-run-cqlsh-due-to-python-attribute-error?noredirect=1#comment131807816_74673247]
Found out that the user was using Python 3.11, and I was able to reproduce it
with that.

{{AttributeError: module 're' has no attribute 'sre_parse'}}
Appears to be something specific (again) with Python's synchronizing regex
engine (SRE). Works fine with Python 3.10, so there may have been a(nother)
breaking change in that the re module with 3.11.
