【问题描述】:
我有一个用 RC4 编写的 Angular2 测试应用程序,运行良好。我现在正在尝试将其升级到 RC7,我收到以下错误消息
Error: SyntaxError: Unexpected token <
Evaluating http://localhost:7864/traceur
Error loading http://localhost:7864/traceur
Error loading http://localhost:7864/libs/@angular/http/index.js as "@angular/http" from http://localhost:7864/app/recentActivity/recentActivity.module.js
我的 recentActivity.module 看起来像这样:
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { HttpModule } from '@angular/http';
import { RecentActivityService } from './recentActivity.service';
import { RecentActivityComponent } from './recentActivity.component';
@NgModule({
imports: [CommonModule, HttpModule],
declarations: [RecentActivityComponent],
exports: [RecentActivityComponent],
providers: [RecentActivityService]
})
export class RecentActivityModule {
}
我无法弄清楚这里有什么问题。如果我查看网络流量,我可以看到下载 @angular/http/index.js 的状态为 200,下载的文件是预期的结果。所以我不知道为什么它说加载它时出错。我还需要看看其他地方。
systemjs.config 在下面
/**
* System configuration for Angular 2 samples
* Adjust as necessary for your application needs.
*/
(function () {
// map tells the System loader where to look for things
var map = {
'app': 'app', // 'dist',
'@angular': 'libs/@angular',
'angular2-in-memory-web-api': 'libs/angular2-in-memory-web-api',
'rxjs': 'libs/rxjs'
};
// packages tells the System loader how to load when no filename and/or no extension
var packages = {
'app': { main: 'main.js', defaultExtension: 'js' },
'rxjs': { defaultExtension: 'js' },
'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' }
};
var ngPackageNames = [
'common',
'compiler',
'core',
'forms',
'http',
'platform-browser',
'platform-browser-dynamic',
'router',
'router-deprecated',
'upgrade'
];
var ngIndexPackageNames = [
'http'
];
// Individual files (~300 requests):
function packIndex(pkgName) {
packages['@angular/' + pkgName] = { main: 'index.js', defaultExtension: 'js' };
}
// Bundled (~40 requests):
function packUmd(pkgName) {
packages['@angular/' + pkgName] = { main: '/bundles/' + pkgName + '.umd.js', defaultExtension: 'js' };
}
// Most environments should use UMD; some (Karma) need the individual index files
var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;
// Add package entries for angular packages
ngPackageNames.forEach(setPackageConfig);
ngIndexPackageNames.forEach(packIndex);
var config = {
//meta: {
// '*.js': {
// scriptLoad:true
// }
//},
map: map,
packages: packages
};
System.config(config);
})(this);

请分享您的 system.config.js

我想通了。既然您向我指出了这一点,请随时提交 yurzui 作为答案。我之所以把它放进去是因为我以前遇到过一些问题 var ngIndexPackageNames = [ 'http' ];我刚刚删除,现在一切正常
