QGIS MongoDB插件

Question

我目前正在尝试使用QGIS插件连接MongoDB，如MongoConnector和加载MongoDB层。但我做不到。

有没有人，谁使用这些插件，或他们是坏的？以下是我在加载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

Couldn't load plugin MongoConnector due to an error when calling its classFactory() method

在安装MongoConnector插件之前，请确保在您的python中安装了"pymongo“。Python和Mongo使用这个来互相交谈。

您可以从他们的官方链接安装它。

在mentioned页面中也提到了pymongo应该是> 3.0，所以它不能使用python2.7参考：https://plugins.qgis.org/plugins/MongoConnector/。

然后再试着安装那个插件。
