Google Recaptcha <re-captcha> 不是已知元素

Question

我想在我的应用程序中添加验证码，但我做不到。我遵循了图书馆的教程 (https://www.npmjs.com/package/ng-recaptcha/v/4.1.0)。我不明白我做错了什么。我在论坛上搜索过类似的问题，但找不到任何解决方案。谢谢

错误：

Error: Uncaught (in promise): Error: Template parse errors:
're-captcha' is not a known element:
1. If 're-captcha' is an Angular component, then verify that it is part of this module.
2. If 're-captcha' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("[ERROR ->]<re-captcha (resolved)="resolved($event)" siteKey="key..."></re-cap"): ng:///LoginPageModule/LoginPage.html@0:0

login.page.ts :

resolved(captchaResponse: string) {

  }

login.page.html :

您只需在导入 LoginPage 组件的地方执行 import RecaptchaModule。
