我在Angular2中有一个非常简单的应用程序,我想捆绑到一个js文件中。
我有以下dir结构:
/-client
|
\-app
- main.ts
- app.module.ts
- app.component.ts
- app.component.spec.ts
-webpack.config.js
- ....
配置文件如下所示:
var webpack = require('webpack');
module.exports = {
entry: {
'app': './app/main.ts'
},
output: {
filename: 'app.js'
},
resolve: {
extensions: ['.ts', '.js']
},
module: {
loaders: [
{
test: /\.ts$/,
loaders: ['awesome-typescript-loader', 'angular2-template-loader']
}
]
}
};
构建完成并生成app.js(1.95MB)但是当我在网页中导入文件时出现以下错误:
app.js:26914Error: The selector "my-app" did not match any elements

任何提示我可能做错了什么?

如果没有看到剩下的代码,很难说清楚。但听起来你要么没有在my-app
中定义app.component.ts
的选择器:
@Component({
selector: 'my-app'
})
export class AppComponent {
...
和/或不在app.module.ts
中引导该组件:
@NgModule({
declarations: [
AppComponent,
...
],
imports: [
BrowserModule,
...
],
],
bootstrap: [AppComponent]
})
export class AppModule { }
