Troubleshooting
Crash on multi-threading
On macOS, flake8 might raise this error when calling requests.get(url)
:
objc[93329]: +[__NSPlaceholderDate initialize] may have been in progress in another thread when fork() was called.
objc[93329]: +[__NSPlaceholderDate initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.
To solve this issue, add this environment variable to .bashrc
(or the initialization file for your favorite shell):
export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES

ModuleNotFoundError: No module named ‘nitpick.plugins.XXX’
When upgrading to new versions, old plugins might be renamed in setuptools entry points.
But they might still be present in the entry_points.txt plugin metadata in your virtualenv.
$ rg nitpick.plugins.setup ~/Library/Caches/pypoetry/
/Users/john.doe/Library/Caches/pypoetry/virtualenvs/nitpick-UU_pZ5zs-py3.7/lib/python3.7/site-packages/nitpick-0.24.1.dist-info/entry_points.txt
11:setup_cfg=nitpick.plugins.setup_cfg
Remove and recreate the virtualenv; this should fix it.
During development, you can run invoke clean --venv install --dry
.
It will display the commands that would be executed; remove --dry
to actually run them.
