类型错误:对象不支持属性或方法“entries”(IE11)

aurelia internet-explorer-11 javascript

Vinyl Warmth · 技术社区 · 8 年前

我有一个用Aurelia编写的应用程序需要在IE11中运行。

直到上周应用程序运行正常,但现在我在控制台中尝试运行它时出现以下错误

TypeError: Object doesn't support property or method 'entries'

我不知道是什么引起的。我已经回到一个月前的承诺,在那里应用程序肯定在IE11工作,但我得到同样的错误。

我们正在使用 Yarn 用于包管理 Webpack

我试过看其他的SOF帖子,但我没能找到一个明确的答案,关于我应该做什么-有人能帮忙吗?

编辑:

我刚安装 this polyfill 运行了Webpack,现在我得到了这个错误:

if (!Object.entries)
        Object.entries = function (obj) {
            var ownProps = Object.keys(obj),
                i = ownProps.length,
                resArray = new Array(i); // preallocate the Array
            while (i--)
                resArray[i] = [ownProps[i], obj[ownProps[i]]];

            return resArray;
        };
