Flask-DebugToolbar无法与mongoDB一起使用

Question

我想使用Flask-MongoEngine正常工作，但是我试图使调试工具栏正常工作，并且当我遵循文档时，得到如下所示的回溯。我能够正常运行烧瓶调试工具栏，但是由于我使用MongoDB作为数据库，因此我试图将烧瓶调试工具栏与MongoDB结合使用。我知道以下行是此回溯的原因。

app.config['DEBUG_TB_PANELS'] = ['flask_mongoengine.panels.MongoDebugPanel']

示例代码

from flask import Flask
from flask_debugtoolbar import DebugToolbarExtension

app = Flask(__name__)
app.config['DEBUG_TB_PANELS'] = ['flask_mongoengine.panels.MongoDebugPanel']
db = MongoEngine(app)
toolbar = DebugToolbarExtension(app)

引起回溯的行

app.config['DEBUG_TB_PANELS'] = ['flask_mongoengine.panels.MongoDebugPanel']

自pymongo 3.6.0起，_unpack_respone方法似乎已消失或被重写。 一种解决方法是安装pymongo<3.6.0
