Javascript TypeError:对象没有'；t支持属性或方法'；条目'；（IE11）

我有一个用Aurelia编写的应用程序，需要在IE11中运行

直到上周，该应用程序运行正常，但现在，当我尝试运行它时，控制台中出现以下错误

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

我不知道这是什么原因。我回到了一个月前，应用程序肯定在IE11中工作，但我得到了同样的错误

我试着查看其他SOF帖子，但我还没有找到一个关于我应该做什么的明确答案——有人能帮我吗

编辑：

我刚刚安装并运行了Webpack，现在出现以下错误：

正如人们提到的，修复方法是实现以下polyfill

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;
        };

您需要对Object.entries（）进行多边形填充。您是否在代码库中搜索

对象。条目

？它可能是最近才加上去的。否则，您将需要如上所述的polyfill。如果你不想处理polyfill等问题，那么更容易找到它并替换为非ES6 js。@Akrion我已经更新了我的帖子，因为在安装polyfill后，我遇到了一个不同（类似）的错误。正如我所说，我回到了一个月的承诺，它肯定是工作。我不明白为什么这个问题突然出现了。在其他机器上也一样。@RitwickDey我已经更新了我的原始版本post@VinylWarmth是锁定允许最新版本的软件包，删除node_modules文件夹并运行npm安装。如果没有任何帮助，开始有选择地移除模块（如果可以的话），直到你缩小范围并锁定罪魁祸首。Object.entries（）需要polyfill。您是否在代码库中搜索
