QGIS MongoDB 插件

Question

我目前正在尝试使用 QGIS 插件连接 MongoDB，例如 MongoConnector 和加载 MongoDB 图层。但我无法让它发挥作用。

有没有人在使用这些插件或者它们坏了？这是我为 Load MongoDB Layers plugin

得到的错误

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

Traceback (most recent call last):

这是 MongoConnector 插件

Answer 1

在安装 MongoConnector 插件之前，请确保您的 python 中安装了 "pymongo"。 Python 和 Mongo 用这个互相交谈。

您可以从他们的 official link.

安装它

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

之后再次尝试安装该插件。
