离子2转换为离子3：＆＃34;错误：无法转换程序＆＃34; on＆＃34;离子构建iOS＆＃34;

标签： ios node.js npm ionic2 ionic3

我一直致力于在Apple Mac机器上设置现有的Ionic 2项目。

我已按照here描述的方式复制了我的项目。

解决了一些Xcode问题后，最终应用程序在iPhone iOS物理设备上打开，但在启动画面后显示空白屏幕。

我找到了如何显示一些日志here。日志输入引导我SO thread: "cannot find module ionic-native"。

我总结说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]。

我在一些components和providers中审核了我的代码，以便在需要的地方进行更改： { NativePlugin1, NativePlugin2 } from 'ionic-native'; 至： { NativePlugin1 } from '@ionic-native/native-plugin-1'; { NativePlugin2 } from '@ionic-native/native-plugin-2';

我修改了我的[离子项目文件夹] /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solution of the SO thread I am referencing to中建议的行"ionic-native": "^2.7.0",：

  

你需要删除＆＃34; ionic-native＆＃34;：＆＃34; ^ 3.5.0＆＃34;从你的package.json开始，然后运行npm i。

然后我按顺序启动：sudo npm cache clear，sudo npm install，最后ionic build ios，我得到了：

  

＆＃34;错误：无法转换程序＆＃34;

在此错误之上，我发现有很多与此ionic-native相关的错误：

  

[14:22:15] typescript：src / services / custom-http / custom-http.ts，line：XX 

       Property 'type' does not exist on type 'typeof Network'.

 LXX:     return Network.type;

我现在感到困惑，所以如果有人提示它会受到欢迎。

要完成此处还有一些其他信息： ionic info给出：

我跟着change log update for ionic 3。

我删除了项目启动的node_modules目录：sudo rm -rf node_modules/然后执行了nom install，ionic platform rm ios，ionic platform add ios，最后ionic build ios

我查看了日志，这是他们的内容：

@suraj的附加输入，即班级CustomHttpService，它是[project]/services/custom-http/custom-http.ts中的一项服务，并注入Providers的{​​{1}}部分：

app.module.ts

2 个答案:

答案 0 :(得分：2)

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。 目前使用的打字稿更改为2.2。 如果您打算转移到离子原生3，则需要将package.json更新为当前starter app version。

同时检查changelog代码中离子的任何重大变化。

此外，您需要将每个离子本机插件设置为提供程序并注入构造函数并使用。 检查the docs。 在app.module.ts中，

    @NgModule({
  ...

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

在custom.http.ts

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


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

答案 1 :(得分：0)

遇到同样的错误，在过滤完代码后，语法错误，缺少逗号。尝试查看app.module.ts文件。希望它有所帮助。
