bpo-34632: fix test_importlib with installed CPython by yan12125 · Pull Request #13565 · python/cpython
"Installed" builders on buildbot.python.org [1] run tests on an
installed CPython copy [2]. Running tests in this way requires all
testing data also installed.
This commit fixes the following error during running tests on an
installed copy:
ModuleNotFoundError: No module named 'test.test_importlib.data'
