Question

我正在尝试使用Ahead of Time构建我的Angular4应用程序。构建过程运行正常且没有错误，但是当我运行应用程序时，我在控制台中收到此错误：

ERROR Error: Runtime compiler is not loaded

vendor.ac8dafb….bundle.js:1 WebSocket connection to 'ws://null/algorilla/ws/websocket/' failed: Error in connection establishment: net::ERR_NAME_NOT_RESOLVED
r @ vendor.ac8dafb….bundle.js:1

该应用程序是可导航的，但没有任何作用！我做错了什么？为什么编译的代码引用了运行时编译器？

我不使用任何角度/编译组件或服务。

在我的组件中，我以这种方式引用服务模拟：

@Component({
  selector: 'app-authorization',
  templateUrl: './authorization.component.html',
  providers: [
    { provide: SecurityService, useClass: (environment.mock ? SecurityServiceMock : SecurityService) }
  ]
})

如果var“environment.mock”为true，我使用SecurityServiceMock，否则使用真正的SecurityService。

这可能是问题吗？

这是tsconfig.json：

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "baseUrl": "src",
    "sourceMap": false,
    "declaration": false,

    ],
    "lib": [
      "es2016",
      "dom"
    ]
  }
}

tsconfig.app.json：

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "module": "es2015",
    "baseUrl": "",

  },

    "**/*.spec.ts"

Answer 1

您正在使用Compiler服务中的compileModuleSync，该服务由createDynamicTemplate方法调用。角度编译器cli正在分析您的代码并从您的模板和类（ngFactory文件）创建metadata，并在使用AOT时完全从您的应用程序中删除编译器模块。

如果您想使用AOT，请不要使用angular/compiler包中的任何服务或方法。

您是否可以将package.json文件添加到您的答案中，可能存在未准备AOT的第三方库。

Sitenote： 你嘲笑你的服务的方式看起来有点奇怪，你可以提供服务，然后在environment.mock为真时覆盖它。例如：

let myProviders = [
  SecurityService
];

if(environment.mock) {
  myProviders.push(
    { provide: SecurityService, useClass: SecurityServiceMock }
  )
}

// ...

providers: [
  ...myProviders
]

但这不是Runtime compiler is not loaded错误的原因。

更新

我发现错误是由您正在使用的angular2-busy包引起的。

Answer 2

这是关于WebSocket url检查它在你的代码中看到它。

与'ws：// null / algorilla / ws / websocket /'的WebSocket连接失败：连接建立错误：net :: ERR_NAME_NOT_RESOLVED

你有一个路径的变量，它被设置为null;）

Answer 3

正如@cyrix在评论中所建议的那样，我在nodeModules中搜索了compileModuleSync，并找到了一个使用angular编译器的外部组件。

外部模块是angular2-busy。

删除它解决了问题！
