如果另一个开发者忘记给你一些文件，你会如何调试Cordova/Ionic应用程序？

我要接管一个科尔多瓦/爱奥尼亚项目。我想跑步：

ionic build 

或

但我会遇到如下错误：

[17:13:17]  typescript: node_modules/rxjs/Subject.d.ts, line: 16 
            Class 'Subject<T>' incorrectly extends base class 'Observable<T>'. Types of property 'lift' are 
            incompatible. Type '<R>(operator: Operator<T, R>) => Observable<T>' is not assignable to type '<R>(operator: 
            Operator<T, R>) => Observable<R>'. Type 'Observable<T>' is not assignable to type 'Observable<R>'. Type 'T' 
            is not assignable to type 'R'. 

      L16:  export declare class Subject<T> extends Observable<T> implements ISubscription {
      L17:      observers: Observer<T>[];

[17:13:17]  typescript: src/components/push-notification/push-notification.ts, line: 61 
            Type '{ android: { forceShow: false; sound: true; }; ios: { alert: "true"; badge: false; sound: "true";...' 
            is not assignable to type 'PushOptions'. Types of property 'android' are incompatible. Type '{ forceShow: 
            false; sound: true; }' is not assignable to type 'AndroidPushOptions'. Property 'senderID' is missing in 
            type '{ forceShow: false; sound: true; }'.                         

以及：

我想也许之前的开发人员没有完成他们所有的工作

我花了一周时间阅读了有关Stackoverflow和Github的文章，并遵循了建议，但我无法克服这些错误

---

我该如何调试它，尤其是假设以前的开发人员可能忘记给我一些必要的东西

尝试更新脚本

npm安装@IONAL/app-scripts@latest

---

然后再次运行

很高兴能提供帮助：D
