Pyinstaller-compiled Uvicorn server does not start correctly

Question

When I start the server.exe and it is trying to perform uvicorn.run(), the exception is being thrown:

<         


        

Answer 1

More universal way is too specify the hook:

# extra-hooks/hooks-uvicorn.py
from PyInstaller.utils.hooks import collect_submodules

hiddenimports = collect_submodules('uvicorn')

And run pyinstaller with --additional-hooks-dir extra-hooks. For example:

pyinstaller -y --clean --additional-hooks-dir extra-hooks main.py

But!

If you are using websockets lib just like me. You will face the error:

File "uvicorn\protocols\websockets\websockets_impl.py", line 24, in 
AttributeError: module 'websockets' has no attribute 'WebSocketServerProtocol'
[1844] Failed to execute script main

For this I've found another solution. Add whole uvicorn's dir itself:

# extra-hooks/hooks-uvicorn.py
from PyInstaller.utils.hooks import get_package_paths

datas = [(get_package_paths('uvicorn')[1], 'uvicorn')]

And build exe with the above command.
