webpack 1.x升级过程中的踩坑总结大全

错误：Error: Chunk.entry was removed. Use hasRuntime()

卸载npm uninstall extract-text-webpack-plugin --save-dev

重新下载 npm install extract-text-webpack-plugin@^2.0.0-beta.4

错误：Error: Breaking change: extract now only takes a single argument.

原因是webpack2对loader的配置做了一些调整，修改 ExtractTextPlugin配置即可：

{
 test: /.less$/,
 use: ExtractTextPlugin.extract({
  fallback: 'style-loader',
  use: ['css-loader', 'less-loader']
 })
},
