我目前正在尝试在 Vercel 上托管我的 Flask 应用程序,但我不断收到相同的错误,
TypeError: issubclass() arg 1 must be a class

我尝试将
typing_extension
更改为4.5.0,typing-inspect
更改为0.8.0,并将pydantic
更改为1.10.11(按照here的建议,但我仍然遇到同样的问题。
提前致谢。
我设法找到了答案;我错误地配置了 vercel。 我使用
server.py
作为主要方法,但 vercel 需要 index.py
文件。所以我创建了一个index.py文件,它是一行; from server import app
。
然后vercel.json
:
旧:
{ “版本”:2, “构建”:[ { "src": "./server.py", “使用”:“@vercel/python” } ], “路线”:[ { “src”:“/(.*)”,“dest”:“/server.py” } ] }
新:
{ “版本”:2, “构建”:[ { "src": "./index.py", “使用”:“@vercel/python” } ], “路线”:[ { “src”:“/(.*)”,“dest”:“/” } ] }
