我有一个Angular 4应用程序，如果我在桌面或Android上访问，路由在本地和生产中正常工作。但是在iPhone上，无论是在Chrome还是Safari中，通过单击菜单路由按钮将路由器路由几次后，路由就会停止工作。它总是发生。 我使用Web检查器进行调试并收到消息：
Error: Uncaught (in promise): TypeError: this.router.serializeUrl is not a function. (In 'this.router.serializeUrl(this.urlTree)', 'this.router.serializeUrl' is 6.04722596e-316)
