Deploy cef-python app with py2exe

[juha.m...@gmail.com]

Hello everybody!

I get CEF-python to work in my windows machine and I can run examples successfully. Anyway I don't know what is the best way to deploy a CEF in Windows systems? I tried to use py2exe. It creates a executable with about 20 other files. When I try to run this executable I get error:

C:\c\tools\cefpython\cefpython\examples\test\dist>hello_world.exe
Traceback (most recent call last):
File "hello_world.py", line 4, in <module>
File "c:\python34\lib\site-packages\cefpython3\__init__.py", line 53, in <module>
from . import cefpython_py34 as cefpython
File "<loader>", line 10, in <module>
File "<loader>", line 8, in __load
ImportError: (No module named 'json') 'C:\\c\\tools\\cefpython\\cefpython\\examples\\test\\dist\\cefpython3.cefpython_py34.pyd'


My directory contains the following files:

The "json" package is a hidden import of cefpython. You need to add this dependency, either through py2exe config or by just adding "import json" in your app.

There is an official PyInstaller example that works out of the box:

Thanks. It seemed to work. But now I get the following error:

C:\c\tools\cefpython\cefpython\examples\test\dist>hello_world.exe

You are missing cef/cefpython binary files. These are files with extensions like .dll .bin .dat .pak (including locales/ subdirectory) that are in the cefpython3 package directory.
