对象键后的字符无效-geojson中的对象键是什么？

我正在将以下文本文件导入geojson：

{"type":"FeatureCollection","features":[{"type":"Feature","geometry":{type":"LineString","coordinates":[[-122.029517,37.976152]]},"properties":{"name":"thing","origin":"somewhere","end":"blah"}}]}

mongoimport-vvv-db-collection-file

长详细输出为：

<Date, etc> -0700   using 4 decoding workers
<Date, etc> -0700   using 1 insert workers
<Date, etc> -0700   filesize: 921 bytes
<Date, etc> -0700   using fields: 
<Date, etc> -0700   connected to: localhost
<Date, etc> -0700   ns: <db>.<collection>
<Date, etc> -0700   connected to node type: standalone
<Date, etc> -0700   standalone server: setting write concern w to 1
<Date, etc> -0700   using write concern: w='1', j=false, fsync=false, wtimeout=0
<Date, etc> -0700   Failed: error processing document #1: invalid character '"' after object key
<Date, etc> -0700   standalone server: setting write concern w to 1
<Date, etc> -0700   using write concern: w='1', j=false, fsync=false, wtimeout=0
<Date, etc> -0700   imported 0 documents

如您所见，错误是对象键后的无效字符“”。然而，引用是必要的。有没有简单的解决办法

似乎没有正确引用单词类型的第三个实例。如果在该单词之前添加双引号，则应该能够导入而不会出现任何问题
