webpack.config.js配置步骤

　　配置less环境

　　在方法 　　getStyleLoaders，添加代码：

　　　　{loader:require.resolve('less-loader')}

 

 增加代码

　　

if (preProcessor === "less-loader") {
        loaders.push(
          {
            loader: require.resolve(preProcessor),
            options: {
              sourceMap: isEnvProduction && shouldUseSourceMap,
              modifyVars: {
                '@primary-color':'#f40'
              },
              javascriptEnabled: true,
            },
          }
        );
 
　　

 

切记开启

babel-plugin-import的less开关，否则设置主题不生效

 "plugins": [
      [
        "import",
        {
          "libraryName": "antd",
          "libraryDirectory": "es",
          "style": true
        }
      ]
