Answer 1

当您使用npm安装bson模块时，听起来没有安装gcc / g ++ / make / python 2.x。首先尝试安装它们，然后使用npm重新安装bson。

Answer 2

实际错误是由4.0版本中的快速更改引起的。大多数包含的中间件现在都是“独立”的npm包。您可以阅读有关更改的更多信息here。

关于Failed to load c++ bson extension, using pure JS version.错误，您可能缺少python / gcc。您可以在此处详细了解此错误：node.js - Failed to load c++ bson extension。如果这不能解决您的问题，请尝试删除/重新安装驱动程序/插件。
