ember.js - Ember >2.2.0 未定义获取 regeneratorRuntime

Question

所以我正在使用 Ember 的服务内的迭代器。该代码使用旧样式脚本工作，我无法使用 ES2015 样式

ReferenceError: regeneratorRuntime is not defined

    stuff[Symbol.iterator] = function *(){
        debugger;
        let properties = Object.keys(this);
        for(let p of properties){
            yield this[p];
        }
    };

我知道这是因为函数上新的“*”运算符。我看过答案https://stackoverflow.com/a/28978619/24862描述了必须加载 browser-polyfill npm 但我有点不清楚如何让它在 ember 框架内工作。有人成功做到这一点吗？或者我应该放弃直到 Ember 支持它。

Answer 1

Polyfill

Babel comes with a polyfill that includes a custom regenerator runtime and core-js. Many transformations will work without it, but for full support you may need to include the polyfill in your app.

您现在应该包含为 ember-cli-babel 而不是 babel。像这样:

var app = new EmberApp(defaults, {
    'ember-cli-babel': {
        includePolyfill: true
    }
}

再生器:

This package implements a fully-functional source transformation that takes the syntax for generators/yield from ECMAScript 2015 or ES2015 and Asynchronous Iteration proposal and spits out efficient JS-of-today (ES5) that behaves the same way.
