我是angular2的新學員。我們知道在angular2中有一種方法可以通過相對路徑來引用文件,通過在組件元數據中定義moduleId : module.id
。但是我想通過這種方式向始終得到以下錯誤:angular2:如何解決錯誤:(SystemJS)模塊沒有定義?
Error: (SystemJS) module is not defined
我已經在這裏建立了一個plunker:a simple angular2 app
文件結構如下,很簡單:
各部分的內容是如下:
config.js:
System.config({
//use typescript for compilation
transpiler: 'typescript',
//typescript compiler options
typescriptOptions: {
emitDecoratorMetadata: true,
module: "commonjs"
},
meta: {
'typescript': {
"exports": "ts"
}
},
paths: {
'npm:': 'https://unpkg.com/'
},
//map tells the System loader where to look for things
map: {
'app': './app',
'@angular/core': 'npm:@angular/core/bundles/core.umd.js',
'@angular/common': 'npm:@angular/common/bundles/common.umd.js',
'@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
'@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
'@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
'@angular/http': 'npm:@angular/http/bundles/http.umd.js',
'@angular/router': 'npm:@angular/router/bundles/router.umd.js',
'@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
'@angular/core/testing': 'npm:@angular/core/bundles/core-testing.umd.js',
'@angular/common/testing': 'npm:@angular/common/bundles/common-testing.umd.js',
'@angular/compiler/testing': 'npm:@angular/compiler/bundles/compiler-testing.umd.js',
'@angular/platform-browser/testing': 'npm:@angular/platform-browser/bundles/platform-browser-testing.umd.js',
'@angular/platform-browser-dynamic/testing': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic-testing.umd.js',
'@angular/http/testing': 'npm:@angular/http/bundles/http-testing.umd.js',
'@angular/router/testing': 'npm:@angular/router/bundles/router-testing.umd.js',
'rxjs': 'npm:rxjs',
'typescript': 'npm:typescript/lib/typescript.js'
},
//packages defines our app package
packages: {
app: {
main: 'main.ts',
defaultExtension: 'ts'
},
rxjs: {
defaultExtension: 'js'
}
}
});
app.component.ts:
import { Component } from '@angular/core';
@Component({
moduleId: module.id,
selector: 'app',
templateUrl: 'app.component.html'
})
export class AppComponent {
}
對於其他文件,你可以參考plunker。我在typescriptOptions中設置了module: "commonjs"
。我的代碼有什麼問題嗎?
嗚嗚,我沒能使其在plunkr工作,但你應該出去檢查環節,它可能會幫助:http://blog.thoughtram.io/angular/2016/06/ 08/component-relative-paths-in-angular-2.html 你可能想看看它說的使用'__moduleName'而不是'module.id'來表示systemJS的底部。 –
是的,你是對的,我會自己添加一個答案 – ahwyX100
