AoT 编译 module.id 错误 Angular 2?

AoT compilation module.id error Angular 2?

我想为我的 angular 2 项目编译 AoT。

我已将我的应用程序分成 js 目录,我生成的所有 .js 文件都在该目录中,还有一个 app 目录,我将我的 .ts.html.css 个文件放在一起。

对于 AoT 编译,我使用 tsconfig.aot.json

{
  "compilerOptions": {
    "target": "es2015",
    "module": "es2015",
    "moduleResolution": "node",
    "declaration": false,
    "removeComments": true,
    "noLib": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": ["es6", "es2015", "dom"],
    "sourceMap": true,
    "pretty": true,
    "allowUnreachableCode": false,
    "allowUnusedLabels": false,
    "noImplicitAny": true,
    "noImplicitReturns": true,
    "noImplicitUseStrict": false,
    "noFallthroughCasesInSwitch": true,
    "outDir": "js",
    "typeRoots": [
      "./node_modules/@types",
      "./node_modules"
    ],
    "types": [
    ]
  },
  "files": [
    "app/main.ts"
  ],
  "exclude": [
    "node_modules",
    "js",
    "app"
  ],
  "compileOnSave": false
}

和脚本:"ngc": "ngc -p tsconfig.aot.json && npm run copy \"app/*\" \"compiled\" "

目前我有这样的组件:

 @Component({
    selector: 'fs-mainbar',
    templateUrl: 'app/mainbar/mainbar.component.html'
 })
export class MainbarComponent {

但是当我尝试 运行 脚本时,它给我这个错误:

> angular-quickstart@1.0.0 ngc C:\dev_escal\project\escal\ui\src\main\webapp
> ngc -p tsconfig.aot.json && npm run copy "app/*" "compiled"

好吧,我应该使用 module.id,但因为我已将我的应用程序分成 jsapp 文件夹,所以我必须像这样使用它:

 @Component({
     moduleId: module.id.replace("/js/", "/app/"),
     selector: 'escl-mainbar',
     templateUrl: './mainbar.component.html'
 })
export class MainbarComponent {

这怎么给我这个错误:

> angular-quickstart@1.0.0 ngc C:\dev_escal\project\escal\ui\src\main\webapp
> ngc -p tsconfig.aot.json && npm run copy "app/*" "compiled"

Error encountered resolving symbol values statically. Calling function 'module', function calls are not supported. Consider replacing the function or lambda with a re
ference to an exported function, resolving symbol MainbarComponent in C:/dev_escal/project/escal/ui/src/main/webapp/app/mainbar/mainbar.component.ts, resolving symbol
 MainbarComponent in C:/dev_escal/project/escal/ui/src/main/webapp/app/mainbar/mainbar.component.ts

所以我从这里开始几乎被困住了。我怎样才能解决这个问题?欢迎任何帮助:)

关于 github 的问题:

https://github.com/angular/angular/issues/14374

试试这个:

 export function moduleId() {
     return module.id.replace("/js/", "/app/");
 }

 @Component({
     moduleId: moduleId(),
     selector: 'escl-mainbar',
     templateUrl: './mainbar.component.html'
 })
export class MainbarComponent { }
