Question

我正在尝试在安装npm模块后启动一个项目。

当我输入npm start时，我得到：

There is an error in your gulpfile: 
SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode
    at exports.runInThisContext (vm.js:53:16)
    at Module._compile (module.js:373:25)

    at Module._compile (module.js:409:26)
    at Object.Module._extensions..js (module.js:416:10)

此外，此错误旁边还有其他错误：

我已经开始克隆项目了。该项目已成功克隆。

非常感谢您的帮助。

查看错误消息

在严格模式之外尚不支持块范围的声明（let，const，function，class）

似乎问题来自于代码是使用EcmaScript 6编写的，并且您使用的是还没有完全支持ES6的nodejs v4。尝试升级到具有更好ES6支持的nodejs v6，并且可能更新一些npm依赖项。

npm ERR！ node v4.6.0
