我选择了getting started with Angular2 tutorial格式,只添加了angularfire2部分。
上的步骤安装了firebase和angularfire2以下是我的systemjs.config.js
/**
* System configuration for Angular 2 samples
* Adjust as necessary for your application needs.
*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
// angular bundles
'@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',
// other libraries
'rxjs': 'npm:rxjs',
'angular2-in-memory-web-api': 'npm:angular2-in-memory-web-api',
'angularfire2': 'npm:angularfire2'
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
},
'angular2-in-memory-web-api': {
main: './index.js',
defaultExtension: 'js'
},
angularfire2: {
main: 'index.js',
defautExtension: 'js'
}
}
});
})(this);
然后我就像这样导入它:
import { AngularFireModule } from 'angularfire2';
然后我不断收到此错误:
任何暗示发生了什么?

你的配置将angularfire2映射到node_modules/angularfire2/index.js
,编写的是es6,因此SystemJS尝试使用traceur编译它,但找不到它。
简单的解决方法是配置它,以便在angular2/bundles/angularFire2.umd.js
而非index.js
中加载捆绑包。
angularfire2
packages
angularfire2: {
main: 'index.js'
需要更改为
angularfire2: {
main: 'bundles/angularFire2.umd.js'
此外,angularFire依赖于Firebase,因此,正如@Jonathon Oates在回答中所说,您还需要为Firebase提供配置。

谢谢@artem - 我遇到了同样的问题!
您可能还需要在map
中引用Firebase,例如
'firebase': 'npm:firebase'
将Firebase添加到您的packages
,例如
'angularfire2': {
main: './bundles/angularFire2.umd.js',
defaultExtension: 'js'
},
'firebase': {
main: './firebase.js',
defaultExtension: 'js'
}
否则,您可能会看到Firebase发生新的404错误。
