Cronjobs run in a different environment from your typical bash shell. You need to activate the virtualenv before running the cronjob.

Let's say that you have a python file called '/a/b/main.py' and a virtualenv '/a/b/env'. Here's an example cronjob to run the script every night at 12am (create with crontab -e):

0 0 * * * source /a/b/env/bin/activate && python /a/b/main.py

GOTCHA: cron runs by default in the sh shell, not bash. If you want to use bash you need to explicitly specify this (e.g. /bin/bash ./something.sh) or define the SHELL env var in your crontab (include SHELL=/bin/bash at the top)
