“运行时错误区域已加载"在离子 3 [英] "Runtime Error Zone already loaded" in ionic 3

问题描述

我正在使用 ionic 3 和 Firebase 4.13.1 版的 Firebase 身份验证开发我的项目.我安装了 Angularfire2.我创建了一个注册表并在使用 ionic-lab 测试我的应用程序时成功地将用户详细信息放入了 firebase 数据库.但是，当我关闭并重新打开我的项目时出现了以下错误:

ERROR in ...node_modules/angularfire2/firebase.app.module.d.ts (10,22):FirebaseApp"类错误地实现了FirebaseApp"类.您的意思是扩展FirebaseApp"并将其成员作为子类继承吗?FirebaseApp"类型中缺少automaticDataCollectionEnabled"属性.

我通过将这一行 automaticDataCollectionEnabled: boolean; 添加到这个类中解决了上面的错误 export declare class FirebaseApp implements _FirebaseApp { }

现在我无法运行我的应用程序，因为它现在给我一个新错误:

运行时错误区域已加载.

堆栈

错误:区域已经加载.在 http://localhost:8100/build/vendor.js:117594:15在 http://localhost:8100/build/vendor.js:118206:3在功能 (http://localhost:8100/build/vendor.js:117571:10)在对象<匿名>(http://localhost:8100/build/vendor.js:117574:2)在对象<匿名>(http://localhost:8100/build/vendor.js:120624:30)在 __webpack_require__ (http://localhost:8100/build/vendor.js:55:30)在 Object.defineProperty.value (http://localhost:8100/build/vendor.js:69092:66)在 __webpack_require__ (http://localhost:8100/build/vendor.js:55:30)在对象<匿名>(http://localhost:8100/build/vendor.js:117089:72)在 __webpack_require__ (http://localhost:8100/build/vendor.js:55:30)

我想我可能会加载模块两次，所以我尝试删除:<script src="build/vendor.js"></script> 从 index.html 得到一个新的运行时错误:webpack Jsonp 未定义.所以我把脚本放回去了.

我现在被困住了，非常感谢任何帮助.

解决方案

就做

npm install @firebase/app@latest --save

和

npm install firebase angularfire2 --save

所以一切都是最新的.所以你现在可能会再次收到这个错误:

<块引用>

node_modules/angularfire2/firebase.app.module.d.ts (10,22):FirebaseApp"类错误地实现了FirebaseApp"类.您的意思是扩展FirebaseApp"并将其成员作为子类继承吗?FirebaseApp"类型中缺少automaticDataCollectionEnabled"属性

要修复它，请将 "automaticDataCollectionEnabled: boolean;" 行添加到 node_modulesangularfire2firebase.app.module.d.ts

export 声明类 FirebaseApp 实现 FBApp {名称:字符串；自动数据收集启用:布尔值；//添加这一行选项: {};身份验证:() =>FirebaseAuth;数据库:() =>火力基地数据库；消息传递:() =>Firebase 消息传递；存储:() =>Firebase 存储；删除:() =>承诺;Firestore: () =>FirebaseFirestore;}

所以现在应该修复了.如果不是，您必须尝试我的第二个解决方案:

npm i -S @firebase/app

然后进入您的 package.json 文件并将依赖项中这两行的版本号更新为以下内容:

"angularfire2": "5.0.0-rc.3","firebase": "4.6.0",

全新安装后:

npm 安装

然后再次发球，它应该再次起作用:

I am developing my project in ionic 3 and Firebase Authentication on Firebase Version 4.13.1. I installed Angularfire2. I created a registration form and successfully put the user details into the firebase database when testing my app using ionic-lab. However the issue came when I closed and re-opened my project, I got the following error:

ERROR in ...node_modules/angularfire2/firebase.app.module.d.ts (10,22): Class 'FirebaseApp' incorrectly implements class 'FirebaseApp'. Did you mean to extend 'FirebaseApp' and inherit its members as a subclass? Property 'automaticDataCollectionEnabled' is missing in type 'FirebaseApp'.

I solved the error above by adding this line automaticDataCollectionEnabled: boolean; into this class export declare class FirebaseApp implements _FirebaseApp { }

Now I can't run my App because it is now giving me a new error:

Runtime Error Zone Already loaded.

Stack

Error: Zone already loaded.

I thought I might be loading the module twice so I tried to remove: <script src="build/vendor.js"></script> from index.html and got a new Runtime Error: webpack Jsonp is not defined. so I put the script back.

I am stuck now, any help is greatly appreciated.

解决方案

Just do

npm install @firebase/app@latest --save

and

npm install firebase angularfire2 --save

so everything is up to date. So you will probably get this error now again:

node_modules/angularfire2/firebase.app.module.d.ts (10,22): Class 'FirebaseApp' incorrectly implements class 'FirebaseApp'. Did you mean to extend 'FirebaseApp' and inherit its members as a subclass? Property 'automaticDataCollectionEnabled' is missing in type 'FirebaseApp

to fix it add the line "automaticDataCollectionEnabled: boolean;" to the node_modulesangularfire2firebase.app.module.d.ts

export declare class FirebaseApp implements FBApp {
    name: string;
    automaticDataCollectionEnabled: boolean; // add this line
    options: {};
    auth: () => FirebaseAuth;
    database: () => FirebaseDatabase;
    messaging: () => FirebaseMessaging;
    storage: () => FirebaseStorage;
    delete: () => Promise;
    firestore: () => FirebaseFirestore;
}

So now it should be fixed. If not you have to try my second solution:

npm i -S @firebase/app

then go into your package.json file and update the version numbers of this two lines in your dependencies to the following:

"angularfire2": "5.0.0-rc.3",
"firebase": "4.6.0",

after the do a fresh install:

npm install

and then do a serve again and it should be working again:

ionic serve
