CoverageException: Can't add arcs to existing line data

Issue #476 invalid
Anonymous created an issue

While testing with: coverage==4.0.3 django-nose==1.4.3

With arguments: '--cover-branches', '--with-coverage', '--cover-package=personalfinance.services',

I get:

File "pythonenv\lib\site-packages\coverage\data.py", line 363, in add_arcs raise CoverageException("Can't add arcs to existing line data") coverage.misc.CoverageException: Can't add arcs to existing line data

    Not the original raiser of the issue, but finding this was useful - I ran into the same error (having first done a run without --cover-branches), but putting --cover-erase into the command line as well made it run correctly. Thank you Ned for the note about cleaning existing data files before running coverage again.
