我有一个由大约2000条记录组成的JSON文件。与Mongo数据库中的文档相对应的每条记录的格式如下：

{jobID:"2597401",
account:"XXXXX",
user:"YYYYY",
pkgT:{"pgi/7.2-5":{libA:["libpgc.so"],flavor:["default"]}},     
startEpoch:"1338497979",
runTime:"1022",
execType:"user:binary",
exec:"/share/home/01482/XXXXX/appker/ranger/NPB3.3.1/NPB3.3-MPI/bin/ft.D.64",
numNodes:"4",
sha1:"5a79879235aa31b6a46e73b43879428e2a175db5",
execEpoch:1336766742,
execModify: new Date("Fri May 11 15:05:42 2012"),
startTime: new Date("Thu May 31 15:59:39 2012"),
numCores:"64",
sizeT:{bss:"1881400168",text:"239574",data:"22504"}},

在JSON文件中，每条记录都在一行上，唯一的换行符是在每条记录的末尾。因此，文档中的每一行都以“{jobID：”...我正在尝试使用以下命令将它们导入到一个Mongo数据库中：

mongoimport --db dbName --collection collectionName --file fileName.json

但是，我得到以下错误：

我不知道问题出在哪里。有谁能推荐一个解决方案吗？
