I am having trouble getting Cassandra up and running. I have downloaded Cassandra 2.0.1 and Python 3.3.2.

Upon starting the CLI for cassandra I get an error:

C:\Dev\ApacheCassandra\apache-cassandra-2.0.1\bin>python cqlsh
  File "cqlsh", line 95
    except ImportError, e:
                      ^
SyntaxError: invalid syntax

Any suggestions? I am going to downgrade python to 2.7 and see if that fixes my issue.

Thanks!

The version of Cassandra that you are using is only compatible with Python 2.x.

The following syntax:

except ImportError, e:

was deprecated in Python 2.7 and removed in Python 3.x. Nowadays, you use the as keyword:

except ImportError as e:

This means that you need to either downgrade to Python 2.x or get a version of Cassandra that is compatible with Python 3.x.
