generic

解决方案

  1. 90% 成功率 Define a Starlette app instance and pass it to uvicorn. 
    from starlette.applications import Starlette
app = Starlette()
# Then run: uvicorn main:app
  2. 85% 成功率 Ensure the server command references the correct module and app variable. 
    uvicorn mymodule:app --reload

无效尝试

常见但无效的做法:

  1. Trying to run the server without defining the app variable. 80% 失败

    The server expects an ASGI application object; without it, it fails.

  2. Using a wrong file name in the server command. 70% 失败

    The server cannot find the app if the module path is incorrect.
