How to Fix Python Nose: Coverage not available: unable to import coverage module

I can't seem to get code coverage with Nose to work, despite having the plugin installed.

Any ideas on how to fix this?

Have you tried pip install coverage? The coverage plugin depends on separate coverage module, which is not a nose's dependency, so needs to be installed manually.

Validate if the coverage module is working by itself via coverage --version. I had a case that it was not working due to the lack of SQLite modules in my python installation from the source. I reinstalled python with SQLite extension to fix the issue.
