This can also occur if - you are running your tests in parallel (eg; python manage.py test --parallel=3`) - and there's an import error. In such a case; your test runner is unable to report the import error and instead reports a _pickle.PicklingError. This happens because of this bug(https://bugs.python.org/issue31297) in python. The bug appears to have been fixed in python2 but was NOT backported to python2.7
To detect the actual import error; run your tests in sequence(--parallel=1) On Monday, 29 February 2016 20:13:08 UTC+3, girish ramnani wrote: > > when running the django test in parallel using the runner.py . > _pickle.PicklingError: Can't pickle <class > 'unittest.loader.ModuleImportFailure'>: attribute lookup > ModuleImportFailure on unittest.loader failed > > error is thrown, and when the runner is run using a single process. the > test suite executes. > > I am using a new virtualenv with django installed in editable mode. > -- You received this message because you are subscribed to the Google Groups "Django users" group.
