控制台不是让你看issues嘛。。。

1.更新依赖包，这是原话，如果你不知道这个警告是什么，你可以忽视它，它会随着时间消失。

If you have no clue what this is all about, you can safely ignore the deprecation warning. It will disappear over time if you keep your packages up-to-date.

2.在 webpack.config.js 加上 process.traceDeprecation = true,不过你得找到哪个 loader 出现这个警告的

If you're a webpack user who is using another loader, you can set process.traceDeprecation = true in your webpack.config.js to find out which loader is causing this deprecation warning.
