我真的不知道我的代码来自哪里。经过一个月的非tdd开发，我已经准备好了所有的单元测试。
有办法诊断吗？
最佳答案
UglifyJs不支持ES6。该错误很可能是方法的速记语法。例如:
const obj = {
method() {
// ...
}
};
看到开头的括号时，它期望使用冒号代替，如下所示:
const obj = {
method: function() {
// ...
}
};
它告诉您块中的确切行，因此请看一下它。在您发布的错误消息中，它是:
[1.350b2d8a46d91e3c0911.chunk.js:20075,15]
^ ^ ^
filename line column
然后，您可以简单地在项目中搜索看到的标识符。如果您不想搜索整个项目，则可以使用
--display-chunks标志运行webpack。这将显示各个模块中包含的模块，因此您只需要查看这些模块即可。您可以告诉babel使用babel插件transform-es2015-shorthand-properties转换速记语法，而不必替换所有速记语法。
记录在案:单元测试不会发现此类错误。
