Packaged app cannot import name enum_type_wrapper from google.protobuf.internal

[Glenn Ramsey]

Hi,

On OSX I'm getting this error related to google.protobuf when running my
packaged app.

Traceback (most recent call last):
File "<string>", line 11, in <module>
File "/path/to/PyInstaller/loader/pyi_importers.py", line 270, in load_module
exec(bytecode, module.__dict__)

File "/path/to/PyInstaller/build/main/out00-PYZ.pyz/Interface.session_pb2",
line 4, in <module>
ImportError: cannot import name enum_type_wrapper

The line with the error is:

from google.protobuf.internal import enum_type_wrapper

warnmain.txt says it couldn't find the module, although it is there:

...
W: no module named google.protobuf.internal.enum_type_wrapper (top-level import
by Interface.session_pb2)
...

Inspecting the executable with archive_viewer.py shows that the other protobuf
modules were included.

How do I fix this?

This is with the latest from the develop branch.

Explicitly import that module in your code?

[Glenn Ramsey]

It turned out to be that I had an old version of protobuf that didn't have that
file and it was getting picked up by PyInstaller instead of the right one, but
when I ran the code manually it was getting the newer version.
