Description Jens Troeger 2020-08-21 22:22:39 UTC 
Description:
We have just updated to LibreOffice 6.4.6.2 40(Build:2), and now Python’s modules fail to import:

$ PYTHONPATH=/usr/lib64/libreoffice/program/ python3.8
Python 3.8.5 (default, Aug 21 2020, 13:17:56) 
[GCC 9.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import uno
>>> from com.sun.star.text import ReferenceFieldSource
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/libreoffice/program/uno.py", line 436, in _uno_import
    raise uno_import_exc
  File "/usr/lib64/libreoffice/program/uno.py", line 358, in _uno_import
    return _builtin_import(name, *optargs, **kwargs)
ImportError: No module named 'com' (or 'com.sun.star.text.ReferenceFieldSource' is unknown)
>>> 

Same with Python 3.7. Now rolling back to 6.4.5.2 which hopefully fixes the issue. 

Is this a regression? Something I’m missing? Anything changed here? I noticed that 6.4.6.2 is not listed below as an “official” release?

Steps to Reproduce:
See above.

Actual Results:
Python import exception.

Expected Results:
Successful import of Python modules.


Reproducible: Always


User Profile Reset: Yes

Comment 2 Kevin Suo 2020-10-22 07:34:13 UTC 
I do reproduce with version 6.4.6.2 release and also on libreoffice-7-0 branch, when running:
from com.sun.star.text import ReferenceFieldSource.

The first import, "import uno" is successful.
Comment 3 Kevin Suo 2020-10-23 09:31:48 UTC 
The import of com.sun.start.* is successful when I use the python shell with the following extension:

On pc Debian x86-64 with master sources updated today, I don't reproduce this.
Python 3.8.12 (default, Jan 22 2022, 17:24:40) 
[Clang 13.0.1 ] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import uno
>>> from com.sun.star.text import ReferenceFieldSource

Debian testing provides LO 7.3.0.2, I don't see any Python binary in a "libreoffice" subdir in "/usr" so can't test it.

@Julien Nabet
the python-interpreter on Debian (also linked to LO ) is: /usr/bin/python
