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

I encountered the same problem. And I found it's a job of hiddenimports,It's useful to modify the following lines in xxx.spec:

a = Analysis(['xxx.py'], 
             hiddenimports=['uvicorn.logging'], 
             )

however, there will still be other similar problems. So, I try to add all files of uvicorn,and it works with:

hiddenimports=['uvicorn.lifespan.off','uvicorn.lifespan.on','uvicorn.lifespan',
'uvicorn.protocols.websockets.auto','uvicorn.protocols.websockets.wsproto_impl',
'uvicorn.protocols.websockets_impl','uvicorn.protocols.http.auto',
'uvicorn.protocols.http.h11_impl','uvicorn.protocols.http.httptools_impl',
'uvicorn.protocols.websockets','uvicorn.protocols.http','uvicorn.protocols',
'uvicorn.loops.auto','uvicorn.loops.asyncio','uvicorn.loops.uvloop','uvicorn.loops',
'uvicorn.logging'],

then, run:

pyinstaller xxx.spec
