Question

所以，我得到的是以下内容：

core.js:1673 ERROR Error: Uncaught (in promise): Error: BrowserModule has already been loaded. 
If you need access to common directives such as NgIf and NgFor from a lazy loaded module, import CommonModule instead.
Error: BrowserModule has already been loaded. If you need access to common directives such as NgIf and NgFor from a lazy loaded module, import CommonModule instead.

我已经从这两篇文章中寻求帮助：

https://stackoverflow.com/questions/52860517/getting-browsermodule-already-loaded-despite-not-importing-it-in-lazy-loaded-mod

AND

https://stackoverflow.com/questions/39286667/browsermodule-has-already-been-loaded-error

我从子组件... module.ts文件中删除了BrowserAnimationsModule和BrowserModule的所有实例，因为前者有14个实例，后者有4个实例。

这14个实例是实际的子文件夹，其中将... module.ts文件导入到app.module.ts中。

我已经尝试过，当我在主页上单击“登录”时，上面出现了该错误。

当我停止该过程时，它首先在1953行附近在platform-browser.js中失败

/**
 * Exports required infrastructure for all Angular apps.
 * Included by defaults in all Angular apps created with the CLI
 * `new` command.
 * Re-exports `CommonModule` and `ApplicationModule`, making their
 * exports and providers available to all apps.
 *
 *
  */
var BrowserModule = /** @class */ (function () {
function BrowserModule(parentModule) {
    if (parentModule) {
        throw new Error("BrowserModule has already been loaded. If you need access to common directives such as NgIf and NgFor from a lazy loaded module, import CommonModule instead.");
    }
}
BrowserModule_1 = BrowserModule;

在NgZone函数中第3778行附近的core.js中，这是麻烦开始的地方

NgZone.prototype.runOutsideAngular = function (fn) {
    return this._outer.run(fn);
};
return NgZone;

任何帮助将不胜感激
