webpack 1.x升级过程中的踩坑总结大全

// 错误提示

Error: Breaking change: extract now only takes a single argument. Either an options object *or* the loader(s).
Example: if your old code looked like this:
 ExtractTextPlugin.extract('style-loader', 'css-loader')

You would change it to:
 ExtractTextPlugin.extract({ fallback: 'style-loader', use: 'css-loader' })

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

{
 filename: pageName + '.html',
 template: __dirname + '/src/' + pageName + '.html',
 chunks: pageConf.chunks,
 inject: true
};

{
 filename: pageName + '.html',
 template: __dirname + '/src/' + pageName + '.html',
 files: {
  chunks: pageConf.chunks,
 },
 inject: true
};
