经检查，是webpack的版本不是  extract-text-webpack-plugin@3.0.2、html-webpack-plugin@2.30.1、less-loader@5.0.0的依赖的版本

warning " > extract-text-webpack-plugin@3.0.2" has incorrect peer dependency "webpack@^3.1.0".
warning " > html-webpack-plugin@2.30.1" has incorrect peer dependency "webpack@1 || ^2 || ^2.1.0-beta || ^2.2.0-rc || ^3".
warning " > less-loader@5.0.0" has unmet peer dependency "less@^2.3.1 || ^3.0.0".

解决：安装正确的依赖（webpack@3.6.0的版本是符合，也许还有其它符合的版本）  yarn add -D webpack@3.6.0
