原因：

• css-loader後面帶了引數modules(打包報錯)
• url-loader後面帶了引數name(引入報錯)

{
  test: /\.css$/,
  use: ExtractTextPlugin.extract({
    fallback: "style-loader",
    use: "css-loader?modules!postcss-loader"
  })
},
{
  test: /\.(svg|ttf|eot|woff)\??.*$/,
  loader: "url-loader?limit=10000&name=fonts/[name].[ext]"
}

解決方案：去掉引數

{
  test: /\.css$/,
  use: ExtractTextPlugin.extract({
    fallback: "style-loader",
    use: "css-loader!postcss-loader"
  })
},
{
  test: /\.(svg|ttf|eot|woff)\??.*$/,
  loader: "url-loader?limit=10000"
}

或者

{
  test: /\.css$/,
  exclude: /node_modules/,
  use: ExtractTextPlugin.extract({
    fallback: "style-loader"
 
,
    use: "css-loader?modules!postcss-loader"
  })
}, {
  test: /\.css$/,
  include: /node_modules/,
  use: ExtractTextPlugin.extract({
    fallback: "style-loader",
    use: "css-loader!postcss-loader"
  })
},
{
  test: /\.(svg|ttf|eot|woff)\??.*$/,
  loader: "url-loader?limit=10000"
}
