mongodb - QGIS MongoDB 插件

Question

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

有人使用这些插件还是它们坏了？ 这是我在加载 MongoDB Layers 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):

这是 MongoConnector 插件

最好， 尼禄

在安装 MongoConnector 插件之前，请确保您的 Python 中已安装“pymongo”。 Python 和 Mongo 使用它来相互通信。

您可以从他们的 official link 安装它.

Mongo Connector 页面中还提到 pymongo 应该 > 3.0 所以它不适用于 python 2.7 引用:https://plugins.qgis.org/plugins/MongoConnector/

之后尝试再次安装该插件。
