New submission from Miro Hrončok <m...@hroncok.cz>: Recently I've been debugging a very nasty bug report that looked like this:
Traceback (most recent call last): File "/usr/bin/jupyter-notebook", line 5, in <module> from notebook.notebookapp import main File "/usr/lib/python3.10/site-packages/notebook/notebookapp.py", line 78, in <module> from .services.kernels.kernelmanager import MappingKernelManager, AsyncMappingKernelManager File "/usr/lib/python3.10/site-packages/notebook/services/kernels/kernelmanager.py", line 18, in <module> from jupyter_client.session import Session File "/usr/lib/python3.10/site-packages/jupyter_client/session.py", line 41, in <module> from jupyter_client.jsonutil import extract_dates, squash_dates, date_default File "/usr/lib/python3.10/site-packages/jupyter_client/jsonutil.py", line 10, in <module> from dateutil.parser import parse as _dateutil_parse File "/usr/lib/python3.10/site-packages/dateutil/parser/__init__.py", line 2, in <module> from ._parser import parse, parser, parserinfo, ParserError File "/usr/lib/python3.10/site-packages/dateutil/parser/_parser.py", line 42, in <module> import six ImportError: bad magic number in 'six': b'\x03\xf3\r\n' For details, see https://bugzilla.redhat.com/2057340 and https://github.com/benjaminp/six/issues/359 What would really make things much easier to understand would be if the exception mentioned what is the path of 'six'. Consider this example: A rogue .py file in /usr/bin: $ sudo touch /usr/bin/copy.py Programs fail with: Traceback (most recent call last): File "/usr/bin/...", line ..., in <module> ... ImportError: cannot import name 'deepcopy' from 'copy' (/usr/bin/copy.py) Immediately I can see there is /usr/bin/copy.py which is probably not supposed to be there. However, when it is a pyc instead: $ sudo touch /usr/bin/copy.pyc Programs fail with: Traceback (most recent call last): File "/usr/bin/...", line ..., in <module> ... ImportError: bad magic number in 'copy': b'' Now I have no idea where "copy" is. The is a request for that exception to give that infomartion. ---------- components: Interpreter Core messages: 413788 nosy: hroncok, petr.viktorin priority: normal severity: normal status: open title: ImportError: bad magic number in ... does not indicate where is that file located type: enhancement versions: Python 3.11 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46835> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
