As issues are disabled on modulegraph2 repo, apologies in advance for adding a quick note here that a lot of tests failed when modulegraph2 tests were run in a RPM VM isolated from the internet. I needed to run nose -e '(TestVirtualEnv|test_six_support|TestPackageFinder|test_distribution|test_all_distributions|test_graph_in_virtual_env|test_graph_distribution|test_dot_graph|test_html_graph|test_report_with_distribution|no_test_stdlib_script)' to get the tests to pass.
