mongodb调试 - ReferenceError:未定义控制台

Question

我有js文件mongodb在我得到console.log调试表达式的地方运行:

use test;
db.city.find().snapshot().forEach(function(city){
    var Pos = city.Pos;

    if (Pos) 
    {
        longLat = Pos.split(" ");
        console.log("longLat");  // for debugging ----------------------------  
        console.log(longLat);

        lon = longLat[0];
        lat = longLat[1];

        if (lon && lat)
        {
            lon = parseFloat(lon);
            lat = parseFloat(lat);
            longLat = [lon, lat];
            city.longLat = longLat;

        }

    }
    db.orgs.save(city);

})

当我运行它...

mongo < /path/to/this/js/file.js

...输出中出错:

ReferenceError: console is not defined

有没有办法记录中间结果以进行调试？

请改用print或printjson方法.这些用于在shell中发出就像console.log()一样:

    if (Pos) 
    {
        longLat = Pos.split(" ");
        print("longLat");  // for debugging ----------------------------  
        printjson(longLat);
