未处理的承诺拒绝SyntaxError Internet Explorer

时间：2018-05-22 21:56:31

标签： webpack axios babel vuex babel-polyfill

我正在使用Vuejs，vuex，webpack，babel-polyfill和axios。

此错误仅出现在我们的生产服务器上的Internet Explorer中。它适用于所有其他浏览器和本地主机。我不确定为什么会这样。

我试图在vuex和axios论坛上寻找这个问题，但没有运气。

我很感激帮助。

这是来自IE11控制台的消息。

谢谢！

答案 0 :(得分：1)

如果您创建的承诺被拒绝且没有明确的.catch，则会显示此错误。我建议你做的唯一一件事就是检查所有代码并验证所有承诺在某些时候都有.catch。

此外，还有一个事件监听器可以帮助您找出拒绝承诺的原因，以及代码中发生的确切位置：

window.addEventListener("unhandledrejection", function (event) {
  console.warn("WARNING: Unhandled promise rejection. Reason: " + event.reason, event);
});
