             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.

{{% python3.11 bin/cqlsh.py}}

{{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.
