从nodejs连接mongodb时意外的严格模式保留字

Question

我安装了mongodb 3.4和nodejs v0.12.2。当我试图从nodejs脚本var MongoClient = require('mongodb').MongoClient;连接mongodb时 它显示

SyntaxError: Unexpected strict mode reserved word
    at exports.runInThisContext (vm.js:73:16)
    at Module._compile (module.js:443:25)

    at Module._compile (module.js:460:26)
    at Object.Module._extensions..js (module.js:478:10)

请帮我解决问题。提前谢谢。
