SyntaxError: missing ) after argument list
可能是版本的问题,导致代码出错
作者您好,现在遇到一个问题:当我执行node app.js时,在执行writeJsonToFile这个函数时,报了一个错误: imgList.forEach is not a function. 然后进行console.log(imgList is ${typeof(imgList)}
); 结果是"imgList is object" 就是说imgList此时为一个对象。可是,一开始我们给imgList定义的类型是数组,什么时候发生的转换?我们需要更改为for...in的形式吗?
Hi, 我Node的版本是7.8,跑你这个的时候,提示taskDone()不是一个函数
