问题描述
我在加载angular2-modal弹出窗口时遇到一些问题.获取此异常意外令牌<-缺少文件lib/angular2-modal/plugins/bootstrap.js" 尝试启动应用程序时进行编译后，它将尝试评估路径
I am facing some issues in loading angular2-modal popup. Getting this exception "Unexpected token < - missing file lib/angular2-modal/plugins/bootstrap.js" After compiling when I try to launch the application, it is trying to evaluate the file in the path
"Evaluating http://localhost:49928/lib/angular2-modal/plugins/bootstrap.js"
但是在指定的位置，没有这样的文件，因此应用程序崩溃了.在lib/angular2-modal/plugins/文件夹下，bootstrap.js文件不存在.但是为什么要在这里寻找这个文件?
But in the specified location no such file exists and hence the application is getting crashed. Under the lib/angular2-modal/plugins/ folder, bootstrap.js file doesn't exists. But why is it looking for this file here?
Error: SyntaxError: Unexpected token <

有什么主意我为什么会出现此错误?为什么要在angular2-modal文件夹下寻找plugins/bootstrap.js文件?
Any ideas why I am getting this error? Why it is looking for plugins/bootstrap.js file under angular2-modal folder?
推荐答案
我已经解决了此问题.
我已经按照下面的方法更改了systemjs.config.js文件，现在可以使用了.
I have changed my systemjs.config.js file as per below and now it works.
(function (global) {
var ngVer = '@4.1.1'; // lock in the angular package version; do not let it float to current!
var routerVer = '@4.1.1'; // lock router version
var formsVer = '@4.1.1'; // lock forms version
var angular2ModalVer = '@2.0.2';
var plugin = 'bootstrap'; // js-native / vex
global.angular2ModalVer = angular2ModalVer;
//map tells the System loader where to look for things
var map = {
'app': 'app',
'@angular': 'https://unpkg.com/@angular', // sufficient if we didn't pin the version
'@angular/router': 'https://unpkg.com/@angular/router' + routerVer,
'@angular/forms': 'https://unpkg.com/@angular/forms' + formsVer,
'angular2-in-memory-web-api': 'https://unpkg.com/angular2-in-memory-web-api', // get latest

};
//packages tells the System loader how to load when no filename and/or no extension
var packages = {

var ngPackageNames = [
'common',
'compiler',
'core',
'http',
'platform-browser',
'platform-browser-dynamic',
'upgrade',
];
// Add map entries for each angular package
// only because we're pinning the version with `ngVer`.
ngPackageNames.forEach(function (pkgName) {
map['@angular/' + pkgName] = 'https://npmcdn.com/@angular/' + pkgName + ngVer;
});
// Add package entries for angular packages
ngPackageNames.concat(['forms', 'router', 'router-deprecated']).forEach(function (pkgName) {

// Individual files (~300 requests):
//packages['@angular/'+pkgName] = { main: 'index.js', defaultExtension: 'js' };
});
var config = {
// DEMO ONLY! REAL CODE SHOULD NOT TRANSPILE IN THE BROWSER
transpiler: 'ts',
typescriptOptions: {
tsconfig: true
},
meta: {
'typescript': {
"exports": "ts"
}
},
map: map,
packages: packages
};
System.config(config);
})(this);
