在 ng build --prod 之后，为什么我在 main.js:1 和 polyfills.js:1 中出现错误，而不是在我创建的组件中出现错误，如何撤消？

编程问答 2022-05-01

问题描述

我想部署一个几乎完成的 Angular 项目，并且为了部署我执行了 ng build --prod。它创建了一个比我部署到服务器的 dist。到这里都明白了，但现在当我更改项目中的内容并执行“ng serve -o”时，我没有看到我在编写这些 console.log 消息的那些组件中设置的控制台消息，而是引用了这些消息来自“main.js:1”和“polyfills.js:1”。

我仍然收到这些控制台消息，但我不知道它是在控制台上的哪个组件中打印出来的。

ERROR TypeError: Cannot read property 'UserzAccessStatus' of undefined
    at main.js:1
    at i.<computed> (polyfills.js:1)
    at e.invokeTask (polyfills.js:1)
    at Object.onInvokeTask (main.js:1)
    at e.invokeTask (polyfills.js:1)
    at t.runTask (polyfills.js:1)
    at t.invokeTask (polyfills.js:1)
    at invoke (polyfills.js:1)
    at r.args.<computed> (polyfills.js:1)
