我只是通过弄清楚如何将它们导入MongoDB来尝试GeoJSON的一些东西。以下是我要导入的JSON数据片段：

我现在要将此数据导入MongoDB实例。当我尝试以下操作时，遇到了一些错误：
mongoimport --db /Users/joe/mongodb-data -c points --file "gemeinden_simplify200.geojson" --jsonArray
connected to: 127.0.0.1
assertion: 13106 nextSafe(): { $err: "Invalid ns [/Users/joe/mongodb-data.points]", code: 16256 }
答案 0 :(得分：1)
我想你需要尝试 -
mongoimport --db test -c points --file "gemeinden_simplify200.geojson" --jsonArray
此处test是数据库名称。
