gulp-babel编译之后运行async报regeneratorRuntime is not

Question

网上找了很多方法，装了插件还是不行babel-plugin-transform-runtime babel-runtime

.babelrc如下

{

    "presets": ["es2015","stage-3"],

    "plugins": [[

        "transform-runtime",

        {

          "helpers": false,

          "polyfill": false,

          "regenerator": true,

          "moduleName": "babel-runtime"

        }

      ]]

}

这是开发依赖

"devDependencies": {

    "babel-core": "^6.26.3",

    "babel-plugin-transform-runtime": "^6.23.0",

    "babel-polyfill": "^6.26.0",

    "babel-preset-es2015": "^6.24.1",

    "babel-preset-latest": "^6.24.1",

    "babel-preset-stage-3": "^6.24.1",

    "babel-runtime": "^6.26.0"

  },

Answer 1

是否有按照官方的要求安装插件：npm install --save-dev babel-plugin-transform-runtimenpm install --save     babel-runtime如果babel-runtime已经被放到devDependencies，那么先uninstall再install一遍。

Answer 2

babel最新版的更新为"presets": ["env"]，照着这个来吧。 安装依赖也比较方便。npm install babel-preset-env --save-dev

Answer 3

补一下package.json里的代码
