Error: No module named cql
Hey all,
I'm using cassandra 2.1.0 on CentOS 6.5
And when I try to run cqlsh on the command line I get this error:
root@beta-new:~] #cqlsh
Python CQL driver not installed, or not on PYTHONPATH.
You might try "easy_install cql".
Python: /usr/local/bin/python
Module load path: ['/usr/local/apache-cassandra-2.1.0/bin',
'/usr/local/lib/python27.zip', '/usr/local/lib/python2.7',
'/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk',
'/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload',
'/root/.local/lib/python2.7/site-packages',
'/usr/local/lib/python2.7/site-packages']
Error: No module named cql
I tried following the advice from the error and ran that command:
[root@beta-new:~] #easy_install cql
Searching for cql
Best match: cql 1.4.0
Processing cql-1.4.0-py2.6.egg
cql 1.4.0 is already the active version in easy-install.pth
Using /usr/lib/python2.6/site-packages/cql-1.4.0-py2.6.egg
Processing dependencies for cql
Finished processing dependencies for cql
And that seems to go ok!
However when I try to run it again:
[root@beta-new:~] #cqlsh
Python CQL driver not installed, or not on PYTHONPATH.
You might try "easy_install cql".
Python: /usr/local/bin/python
Module load path: ['/usr/local/apache-cassandra-2.1.0/bin',
'/usr/local/lib/python27.zip', '/usr/local/lib/python2.7',
'/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk',
'/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload',
'/root/.local/lib/python2.7/site-packages',
'/usr/local/lib/python2.7/site-packages']
Error: No module named cql
I get the same exact error. How on earth do I break out of this feeback
loop?
Thanks!
Tim

Re: Error: No module named cql
Posted by Ben Bromhead <be...@instaclustr.com>.
It looks like easy_install is using python2.6 and installing cql in
the 2.6 packages directory: /usr/lib/python2.6/site-packages/
cqlsh is using the python executable for you environment (which looks
like 2.7) and thus is looking for cql in the site packages dir
(amongst others).
To quickly install the cql module explicitly for python 2.7 run:
python2.7 -m easy_install cql
Though you might also want to sort out your easy_install so it matches
the version of python that is used by default.
