Vue.js 弃用警告：Tapable.plugin 已弃用.在 .hooks 上使用新的 API

弃用信息:

弃用警告:可点击.apply已被弃用.打电话申请

是just a warning:

下面是一个简短的总结，供大家参考.

这是什么信息？

webpack 4使用了一个新的插件系统，并且不推荐以前的API.有两个新警告:

DeprecationWarning: Tapable.apply is deprecated. Call apply on the plugin directly instead
DeprecationWarning: Tapable.plugin is deprecated. Use new API on `.hooks` instead

These are warnings.它们被输出到控制台，以警告我们的用户，他们正在使用过时的API，应该迁移到

How bad are these warnings?

它们只是文本信息，不是错误.If you see a 100 you can ignore it

所以你对此无能为力.

除此之外，我相信您收到了如下错误:

/tmp/my-project> npm run dev

> node build/dev-server.js

您应该将html-webpack-plugin更新为latest version:

npm install --save-dev html-webpack-plugin@3

错误应该会消失.
