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

Question

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

Answer 1

是否有按照官方的要求安装插件：npminstall--save-devbabel-plugin-transform-runtimenpminstall--savebabel-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。npminstallbabel-preset-env--save-dev
