解决方案

　　在引入的ui样式文件的对应处理loader中，将modules.mode设置为global 即可

{
  test: cssRegex,
  exclude: cssModuleRegex,
  use: getStyleLoaders({
    importLoaders: 1,
    sourceMap: isEnvProduction
      ? shouldUseSourceMap
      : isEnvDevelopment,
    modules: {
      mode: "global",
    },
  }),
  // Don't consider CSS imports dead code even if the
  // containing package claims to have no side effects.
  // Remove this when webpack adds a warning or an error for this.
  // See https://github.com/webpack/webpack/issues/6571
  sideEffects: true,
},
