After installing python-unittest, the following errors occur when executing
"import unittest" from a python commandline:
ImportError: No module named StringIO
ImportError: No module named pprint
ImportError: No module named difflib
ImportError: No module named pprint
ImportError: No module named fnmatch
Fix this by adding the missing dependencies to the generator script and run
the generator.
