在导入烧瓶模块（或任何依赖于烧瓶的模块）时，我收到以下错误：

Traceback (most recent call last):
  File "main.py", line 2, in <module>
    from flask import Flask, request, render_template, redirect, abort, make_response
  File "/usr/lib/python3.7/site-packages/flask/__init__.py", line 21, in <module>
    from .app import Flask, Request, Response

    _slash_escape = '\\/' not in _json.dumps('/')
AttributeError: module 'simplejson' has no attribute 'dumps'

我通过编辑上述文件解决了这个问题/usr/lib/python3.7/site-packages/flask/json/__init__.py

将第 21 行从

from itsdangerous import json as _json

至

import json as _json

这不应该是解决此问题的正确方法，因此我将等待正确答案并暂时使用此修复程序。
