webpack使用extract-text-webpack-plugin打包时提示错误

最近使用webpack打包时，报了一个extract-text-webpack-plugin的错误，查找了一下，原来是extract-text-webpack-plugin还不能支持webpack4.0.0以上的版本。在package.json里面看下，果然我使用的webpack版本是v4.16.3，extract-text-webpack-plugin默认安装到的版本是v3.0.2

报错信息：

(node:12712) DeprecationWarning: Tapable.plugin is deprecated. Use new API on `.hooks` instead

                    throw new Error(

解决方法：

npm install --save-dev extract-text-webpack-plugin@next

会下载到 [email protected]

然后再打包就OK了~
