我已经构建了一个Ionic 4应用程序.一切正常,但是每当我从Android设备在Chrome调试窗口中启动应用程序时,都会收到以下错误消息:
I've built an Ionic 4 app. Everything works but I get the following error whenever I launch the app in the Chrome debug window from my android device:

我什至不确定它是否引起任何问题.我唯一真正的问题是,当我使用Google身份验证时,大约需要3分钟才能对用户进行身份验证.但是,这是使用Facebook的正常时间.
I'm not even sure if it's causing any issues. The only real issue I have is when I use Google authentication it takes around 3 minutes to authenticate a user. However, it's a normal time with facebook.
任何帮助将不胜感激.目前,我已经在Google上进行了彻底搜索,以寻求有关此问题的帮助.
Any help would greatly be appreciated. At this point I've searched Google thoroughly for help with this problem.
这是我的app.component
This is my app.component
initializeApp() {
if (!firebase.apps.length) {
firebase.initializeApp(firebaseConfig);
this.platform.ready().then(() => {
const unsubscribe = firebase.auth().onAuthStateChanged( user => {
if (!user) {
this.router.navigateByUrl('login');
this.statusBar.styleDefault();
this.splashScreen.hide();
unsubscribe();
} else {
this.router.navigateByUrl('tabs/itinerary-feed');
this.statusBar.styleDefault();
this.splashScreen.hide();
unsubscribe();
}
});
});
}
}
添加其他信息...这会在出现错误之前运行:
Adding additional information...this runs before I get the error:
Angular is running in the development mode. Call enableProdMode() to enable the production mode.

推荐答案
看起来构建成功,但是某些插件引起了错误.
It looks like the build succeeded but some plugin is causing the error.
首先,安装最新的应用程序脚本:
First, install the latest app-scripts:
npm install @ionic/app-scripts@latest --save-dev
应用脚本负责执行实际的构建任务,例如:
App-scripts are responsible for performing the actual building tasks like:
- 并行执行多核处理任务以加快构建速度
- 内存中文件转储和捆绑
- 将源代码移植到ES5JavaScript
然后,删除node_modules&插件文件夹,然后再次运行" npm install
"命令.
Then, remove the node_modules & plugin folder and run "npm install
" command again.
更新
initializeApp()
{
this.platform.ready().then(() => //Fired when Ionic app is ready to listen to device specific events
{
this.statusBar.styleDefault();
this.splashScreen.hide();
if (!firebase.apps.length)
{
firebase.initializeApp(firebaseConfig);
const unsubscribe = firebase.auth().onAuthStateChanged( user => {
if (!user) {
this.router.navigateByUrl('login');
//unsubscribe(); //I Can't understand this piece of code. It seems unnecessary here
} else {
this.router.navigateByUrl('tabs/itinerary-feed');
//unsubscribe();//I Can't understand this piece of code. It seems unnecessary here
}
});
}
});
}
