Cannot use shelve without manual import of dbm.dumb

python -m nuitka --version

Nuitka was installed using pip. Python was installed using the binary installer.

import shelve

pConfig = shelve.open("config")
pConfig.close()

Compiling the above code example with the following options:

python -m nuitka --standalone --follow-imports test.py

yields the following output when executing the binary:

Traceback (most recent call last):
  File "C:\Users\<user>\nuitkaTest\test.py", line 3, in <module>
  File "C:\Users\<user>\nuitkaTest\shelve.py", line 243, in open
  File "C:\Users\<user>\nuitkaTest\shelve.py", line 226, in __init__
ModuleNotFoundError: No module named 'dbm'

Using the current develop version of nuitka (0.8rc6) yields the same error.

If I add import dbm in front of import shelve, I get an error saying it couldn’t find any implementation of dbm (neither dbm.gnu, nor dbm.ndbm, nor dbm.dumb) If I add import dbm.dumb it works fine.

Nuitka version 0.6.19.7 worked perfectly fine.

This is now on develop and will be in 0.8 release.
