【问题描述】：

我目前正在尝试使用 QGIS 插件来连接 MongoDB，例如 MongoConnector 和 Load MongoDB Layers。但我无法让它工作。

有没有人，谁使用这些插件或者它们被破坏了？这是我在加载 MongoDB 层插件时遇到的错误

 Couldn't load plugin qgis-mongodb-loader due to an error when calling its classFactory() method

Traceback (most recent call last):
  File "C:/PROGRA~1/QGISWI~1/apps/qgis-ltr/./python\qgis\utils.py", line 219, in startPlugin
    plugins[packageName] = package.classFactory(iface)

    from .loadMongoDB import loadMongoDB

Python version:

这是用于 MongoConnector 插件的

最好，尼鲁

看到这个similar question，已经解决了。

【解决方案1】：

在安装 MongoConnector 插件之前，请确保您的 python 中安装了“pymongo”。 Python 和 Mongo 使用 this 相互交流。

您可以从他们的official link 安装它。

在Mongo Connector页面中也提到pymongo应该> 3.0 所以它不适用于 python 2.7 参考：https://plugins.qgis.org/plugins/MongoConnector/

然后尝试再次安装该插件。
