我有一个Flask应用程序，它使用mongoengine并在Heroku上运行，我使用了

bson

包，在我将其从

0.5.6

更新到

0.5.7

我开始收到以下错误消息：

请注意，

pymongo>=2.7.1

作为

mongoengine

更新： 删除

bson

并将

pymongo==3.7.2

添加到需求文件后，我得到以下错误：

pymongo>=2.7.1指令覆盖bson安装

从

不要从pypi安装“bson”包。PyMongo有它的拥有bson软件包；执行“easy_install bson”安装第三方与PyMongo不兼容的包

假设您真的想使用第三方bson，您需要

pip卸载bson

（删除通过pymongo包登陆的被覆盖的bson）

pip安装bson

（重新安装py bson软件包）

或者您可以修补pymongo安装以删除collections.abc行（显然您真的不需要它？），但弄乱生产打包代码是值得怀疑的

pymongo模块

您正在尝试使用的py bson模块。

我应该如何使用

pymongo bson

模块？在我的

pip freeze

中，我有

bson==0.5.7

，因为它是我的需求文件的一部分，但是如果

pymonogo

具有相同的功能，我就不必使用它。另外，我没有直接使用

pymongo

，我使用的是

mongoengine==0.16.1

，它安装了

pymongo

，我看到我可以从bson import json_util使用

，但这不是直观的（而且在PyCharm中也会引起一个错误）使用一个我没有安装的软件包。它应该很容易从requirements.txt中删除bson，并包括包含bson软件包的pymongo（mongo不允许将其分开，这很痛苦）。我用您的需求文件完成了这项工作，打开了一个python解释器，并以abc的形式运行了import collections.abc，它没有抛出我在Heroku上运行的问题的错误，因此我无法控制环境的设置。我运行heroku repo:purge_cache-一个应用程序名称，并从Git重新部署该应用程序，现在它似乎正在工作。Hi@shiomiLan只是为了补充讨论，我遇到了这个问题，通过先安装bson，然后安装pymongo，解决了我的heroku部署问题。很有味道。
