Taro 代码的转译是 Babel 管理的,你可以看下能不能改 Babel 设置。

额,还有这种需求么,taro 目前没有配置关闭 babel 编译的选项

可能他在调试时遇到了些问题,因为缺少 sourceMap ,经常在打断点的时候要面对 Babel 过的 ES5 代码。

// node_modules/@tarojs/cli/src/weapp.js
// 我把 defaultBabelConfig 注释掉后自己的babel conf (包括targets等,见下) 才生效

const babelConfig = _.mergeWith({}, defaultBabelConfig, pluginsConfig.babel, (objValue, srcValue) => {
// config/index.js
const config = {
      sourceMap: true,
      presets: [
        ['env', {
          modules: false,
          spec: true,
          // debug: true,
          targets: {
            node: 6,
            chrome: 57,
          },
        }]
      ],

另外taro用的uglify也不支持es6, 换掉这个之前可能没法es6 ready
