I'm getting this error when I try to run the tool migration:

sh ./scripts/migrate_tools/0003_tools.sh install_dependencies
No handlers could be found for logger "docutils"
Repositories will be installed into configured tool_path location  ../shed_tools
Adding new row (or updating an existing row) for repository 'freebayes' in the tool_shed_repository table.

Any ideas?
