意外的标记punc«（»，预期punc从UglifyJS创build块时
尝试使用webpack 2.2.1进行生产构build时出现以下错误：

我真的不知道我的代码从哪里来。 在非tdd开发的一个月后，我刚刚修复了所有的unit testing。
有没有办法来诊断呢？
UglifyJs不支持ES6。 该错误很可能是方法简写语法。 例如：
const obj = { method() { // ... } };
当它看到左括号时，它预期冒号，如下所示：
const obj = { method: function() { // ... } };
有没有办法来诊断呢？
它告诉你大块中的确切线，所以看看它。 在你发布的错误消息是：
[1.350b2d8a46d91e3c0911.chunk.js:20075,15] ^ ^ ^ filename line column
然后，您可以简单地在项目中search您看到的标识符。 如果您不想search整个项目，则可以使用--display-chunks标志运行webpack。 这将显示哪些模块包含在相应的块，所以你只需要看看那些。
而不是必须replace所有的简写语法，你可以告诉babel使用babel插件transform-es2015-shorthand-properties来传递简写语法。
logging：unit testing不会发现这样的错误。
意外令牌punc«（»，预计punc«：»
该错误是指出它期望一个冒号，而不是一个左括号，所以问题可能是关于这样的函数的声明：
var foo = { bar() { console.log('Something'); } }
这将需要改变
var foo = { bar: function() { console.log('Something'); } }
