webpack.config.prod.js 中配置無(wú)效 打包出來(lái)的 標(biāo)簽頁(yè)沒(méi)有加上樣式 postcss-loader 也失效
打包后：

.App {
  text-align: center;
  transform: translateX(5px); }

<div>標(biāo)題<p>45132</p></div>

開(kāi)發(fā)模式：

.App-2R2Ee {
  text-align: center;
  -webkit-transform: translateX(5px);
  -ms-transform: translateX(5px);
  transform: translateX(5px); }

<div class="header-V9F5Y">標(biāo)題<p class="sss-2Irfm">45132</p></div>

配置中是只有scoped.scss 開(kāi)啟css modules
請(qǐng)問(wèn)怎么配置
