Now I'm experiencing this:

[iwuser@erwin-lab2 bin]$ ./cqlsh

Python CQL driver not installed, or not on PYTHONPATH.
You might try "easy_install cql".

Python: /usr/local/bin/python2.6
Module load path: ['./../lib/', './../lib/', '/home/iwuser/dsc-cassandra-2.0.2/bin', '/usr/local/bin/python2.6', '/usr/local/lib/', '/usr/local/lib/python2.6', '/usr/local/lib/python2.6/plat-linux2', '/usr/local/lib/python2.6/lib-tk', '/usr/local/lib/python2.6/lib-old', '/usr/local/lib/python2.6/lib-dynload', '/usr/local/lib/python2.6/site-packages']

Error: can't decompress data; zlib not available

Any idea?

Hello All,

I have installed Cassandra Datastax community edition 2.2 and python 2.6 but when I run ./cqlsh I faced with the following error:
"No appropriate python interpreter found."

I know that the error indicates that I have incompatible Python version but I've already installed Python 2.6 and as it seems cqlsh still uses my old version and not the new 2.6 version.

Any suggestion that shed some light would highly appreciated?

My OS is Linux RHEL 5.

Thanks in advance,
