As part of
DelayedImportErrorModule
, an exception message is created forModuleNotFound
. That message creation uses__frame_data
includingcode_context
. But it raises a secondary TypeError exception iffd["code_context'] is None
.This PR handles the case of no
code_context
by addingor ""
to getfd["code_context"] or ""
See networkx/networkx#7062
I wasn't able to make a test for this easily because I don't know how to create some code for a test with code_context showing up as None. But this change is presumably harmless at worst and hopes to reduce confusion when a moduleNotFound error is raised for a
DelayedImportErrorModule
.
