无法从python中的“flask.helpers”导入名称“_endpoint_from_view_func”

Question

我在 Ubuntu 上运行相同的代码没有问题，但在 Windows10 上运行时出现问题。我还安装了 Flask。我的windows环境配置如下：

$ pip --version
pip 21.1.1 from c:\users\min\appdata\local\programs\python\python37\lib\site-packages\pip (python 3.7)

$ pip show flask

$ pip show flask-restful

当我运行代码时，有错误

from flask_restful import reqparse, Api, Resource

错误是

Exception has occurred: ImportError
cannot import name '_endpoint_from_view_func' from 'flask.helpers' (C:\Users\Min\AppData\Local\Programs\Python\Python37\lib\site-packages\flask\helpers.py)
  File "E:\yulin\python_project\image_text_project_-api\chuanxian_api_module_time_native2.py", line 24, in <module>
    from flask_restful import reqparse, Api, Resource

不知道为什么，请帮帮我，非常感谢。

Answer 1

这是一个等待在这里解决的已知问题。

同时，我建议进行猴子修补：

import flask.scaffold
flask.helpers._endpoint_from_view_func = flask.scaffold._endpoint_from_view_func
import flask_restful
...

Answer 2

就像雷纳托提到的那样，这是一个已知问题。团队已经修复了它。使用最新版本的Flask-RESTful修复了我的问题。例如：

Flask-RESTful==0.3.9
