Surely py2app doesn't assume every extension is .py, or if it does can it be changed?</div></blockquote><div><br></div>Py2app does not assume that every extension is a python file. Given the messasge I'd say that the error occurs in the code path that creates a helper python file that actually loads the exention.</div><div><br></div><div>A little background information: when py2app creates the application bundle all modules are stored in a zipfile and loaded using python's zipimporter. Extensions cannot be stored in the zipfiles because the zipimporter doesn't support that. Py2app therefore creates a placeholder python module in the zipfile that loads the extensions from a directory in the application bundle. </div><div><br></div><div>BTW. could you please create a sample project that demonstrates the problem? I've tried to reproduce your problem on my machine and failed to do so. I did run into another problem, py2app generated an incomplete bundle due to confusion between a _collections submodule in SQLAlchemy and the _collections extension in the stdlib; that's something I'm currently trying to fix.</div><div><br></div><div>Ronald</div><div><blockquote type="cite">
