ERROR: Cannot install -r /home/zuul/src/opendev.org/openstack/freezer/test-requirements.txt (line 23) and astroid==2.1.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested astroid==2.1.0
    pylint 2.3.1 depends on astroid<3 and >=2.2.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
