Redbeat doesn't work with Celery `4.2.0rc1`

Also does not work with 3.1.26.post2

I am currently using the following monkey patch until StrictVersion in schedulers is replaced with pkg_resources.parse_version, the expected supported manner (See pypa/setuptools#1310 (comment))

This is due to StrictVersion throwing a ValueError, a rather unique exception to see on a package import. As is usual one must run the patches before any prior import.

def patch_redbeat():
    ''' Fix https://github.com/sibson/redbeat/issues/88
    '''
    try:
        from redbeat import schedulers
    except ValueError:
        from distutils import version
        cls = version.StrictVersion
        assert isinstance(cls, (type, old_style_class))
        version.StrictVersion = parse_version
        from redbeat import schedulers
        schedulers.StrictVersion = parse_version
        version.StrictVersion = cls
    else:
        if hasattr(schedulers, 'StrictVersion'):
            assert isinstance(schedulers.StrictVersion, type(parse_version))

4.2.1 should work? may be redbeat cant parse string in version

[sibson]

Should be fixed by #96
