问题描述
当我启动 server.exe
并尝试执行 uvicorn.run()
时,抛出异常:
When I start the server.exe
and it is trying to perform uvicorn.run()
, the exception is being thrown:
Traceback (most recent call last):
File "logging\config.py", line 390, in resolve
ModuleNotFoundError: No module named 'uvicorn.logging'
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "logging\config.py", line 542, in configure
File "logging\config.py", line 654, in configure_formatter
File "logging\config.py", line 469, in configure_custom
File "logging\config.py", line 397, in resolve
File "logging\config.py", line 390, in resolve
ValueError: Cannot resolve 'uvicorn.logging.DefaultFormatter': No module named 'uvicorn.logging'
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "server.py", line 82, in <module>
File "server.py", line 21, in run
File "uvicorn\main.py", line 343, in run
File "uvicorn\config.py", line 180, in __init__
File "uvicorn\config.py", line 223, in configure_logging
File "logging\config.py", line 808, in dictConfig
File "logging\config.py", line 545, in configure
ValueError: Unable to configure formatter 'default'
[7932] Failed to execute script server
请注意,uvicorn.logging
模块确实存在,当我在 Python 中执行服务器代码时,它运行正常.
Note that the uvicorn.logging
module does exist and when I perform the server`s code in Python, it operates correctly.
推荐答案
我遇到了同样的问题.我发现这是hiddenimports
的工作,修改xxx.spec
中的以下几行很有用:
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'],
<everything else>)
不过,还是会出现其他类似的问题.所以,我尝试添加 uvicorn
的所有文件,它适用于:
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'],
然后,运行:
pyinstaller xxx.spec
