Ionic 2 转换为 Ionic 3：“离子构建 iOS”上的“错误：无法转换程序”答案

【问题标题】：Ionic 2 convert to Ionic 3 : "Error: Failed to transpile program" on "ionic build iOS"Ionic 2 转换为 Ionic 3：“离子构建 iOS”上的“错误：无法转换程序”

【问题描述】：

我一直致力于在 Apple Mac 机器上设置现有的 Ionic 2 项目。

我已经按照here 的描述复制了我的项目。

在解决了一些 Xcode 问题后，最终应用在 iPhone iOS 物理设备上打开，但在启动屏幕后显示空白屏幕。

我找到了如何显示一些日志here。日志输入将我带到SO thread: "cannot find module ionic-native"。

我得出结论，我必须更新我的项目代码以匹配 new settings to handle ionic-native plugins。

对于每个插件，我应用了以下过程：ionic plugin rm [plugin name]、ionic plugin add [plugin name]、npm install --save @ionic-native/[plugin name]。

我查看了我的代码以在需要的地方进行更改，其中一些 components 和 providers 来自： { NativePlugin1, NativePlugin2 } from 'ionic-native'; 到： { NativePlugin1 } from '@ionic-native/native-plugin-1'; { NativePlugin2 } from '@ionic-native/native-plugin-2';

我修改了我的 [ionic 项目文件夹]/src/app/app.module.ts 并添加了：

// all declaration as it was like "import { NgModule } from '@angular/core';"
//plus declarations added to match new rules and add plugin in providers section
{ NativePlugin1 } from '@ionic-native/native-plugin-1';
{ NativePlugin2 } from '@ionic-native/native-plugin-2';
@NgModule({
  declarations: [
    ...
  ],
  imports: [...
  ],
  bootstrap: [IonicApp],
  entryComponents: [...
  ],
  providers: [
    NativePlugin1,
    NativePlugin2,
    ...
  ]
})
export class AppModule {}

我从我的 package.json 中删除了 "ionic-native": "^2.7.0", 行，正如 solution of the SO thread I am referencing to 中所建议的那样：

您需要从 package.json 中删除 "ionic-native": "^3.5.0" ，然后运行 npm i。

然后我按以下顺序启动：sudo npm cache clear、sudo npm install，最后是ionic build ios，我得到了：

“错误：编译程序失败”

在这个错误之上，我看到很多与ionic-native 相关的错误，比如这个：

[14:22:15] 打字稿：src/services/custom-http/custom-http.ts，行：XX
       Property 'type' does not exist on type 'typeof Network'.

 LXX:     return Network.type;

我现在感觉卡住了，所以如果有人有提示，我会很欢迎。

以下是一些补充信息： ionic info 给：

我关注了change log update for ionic 3。

我删除了我的项目启动的node_modules 目录：sudo rm -rf node_modules/ 然后执行nom install、ionic platform rm ios、ionic platform add ios，最后是ionic build ios。

我查看了日志，这是他们的内容：

@suraj 的附加输入，CustomHttpService 类，它是位于[project]/services/custom-http/custom-http.ts 并注入app.module.ts 的Providers 部分的服务：

import { Injectable } from '@angular/core';
import { Http, Headers, Response, RequestOptions, RequestMethod, Request } from '@angular/http';
import { Observable } from 'rxjs/Observable';
// import { Network } from 'ionic-native';
import { Network } from '@ionic-native/network';


@Injectable()
export class CustomHttpService {
    //other code    

    public connection = () => {
        return Network.type;
    }


    public onDisconnect = ():Observable<any> => {
        return Network.onDisconnect();
    }

    public onConnect = ():Observable<any> => {
        return Network.onConnect();
    }   

}

【解决方案1】：

您已将 ionic-native 更新为 3.x.. 但是您的核心 ionic-angular 仍在 2.0.0-rc0 中，并且所有其他依赖项都较旧。当前使用的 Typescript 已更改为 2.2。如果您打算迁移到 ionic native 3，则需要将您的 package.json 更新为当前的 starter app version。

同时检查 changelog 以了解您的代码中 ionic 的任何重大更改。

您还需要将每个离子原生插件设置为提供程序并注入您的构造函数并使用。检查the docs。在您的 app.module.ts 中，

    @NgModule({
  ...

  providers: [
    ...
    Network 
    ...
  ]
  ...
})
export class AppModule { }

在您的 custom.http.ts 中

constructor(public http:Http,public network:Network
        ){
        console.log("CustomHttpService() starts");
    }
//..other code 


public connection = () => {
        return this.network.type;
    }

【讨论】：

我按照你的建议做了，但仍然抛出同样的错误。我用我所做的那些新动作详细说明了我的问题。
将脚本块中的构建和服务命令更改为引用的 package.json ..如果这不起作用，请尝试更新您的 ionic cli
你有一个例子来说明你的意思：“将脚本块中的构建和服务命令更改为引用的 package.json”？
scripts": { "clean": "ionic-app-scripts clean", "build": "ionic-app-scripts build", "ionic:build": "ionic-app-scripts build", "ionic:serve": "ionic-app-scripts serve" },
错误来自运行 package.json 中的脚本。这是在您执行离子服务时运行的

【解决方案2】：

遇到同样的错误，在过滤代码后出现语法错误，缺少逗号。尝试查看您的 app.module.ts 文件。希望对您有所帮助。
