我试图通过
https://github.com/ng-bootstrap/ng-bootstrap将引导模块添加到我的ng2应用程序.
但是所有的时间得到这个错误:
但是所有的时间得到这个错误:
这是我的索引文件,也许我的文件有一些错误?
index.html的:

解决方法
我遇到过同样的问题.基本上你需要告诉你的systemjs.config在哪里可以找到ng-bootstrap的所有单个组件.
基于ulubeyn的答案,我将以下内容添加到基本的systemjs.config中:
/** * System configuration for Angular 2 samples * Adjust as necessary for your application needs. */ (function (global) { // map tells the System loader where to look for things var map = { 'app': 'app','@angular': 'node_modules/@angular','rxjs': 'node_modules/rxjs','@ng-bootstrap': 'node_modules/@ng-bootstrap','@ng-bootstrap/ng-bootstrap': 'node_modules/@ng-bootstrap/ng-bootstrap' }; // 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','@ng-bootstrap/ng-bootstrap': {main: 'index.js',defaultExtension: 'js'} }; var ngPackageNames = [ 'common',]; var ngBootstrapPackageNames = [ 'accordion','alert','bundles','buttons','carousel','collapse','dropdown','esm','modal','pagination','popover','progressbar','rating','tabset','timepicker','tooltip','typeahead','util' ]; // 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'}; } function ngBootstrapPackIndex(pkgName) { packages['@ng-bootstrap/ng-bootstrap/' + pkgName] = {main: 'index.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); ngBootstrapPackageNames.forEach(ngBootstrapPackIndex); var config = { map: map,packages: packages }; System.config(config); })(this);
详细:
>将’@ ng-bootstrap / ng-bootstrap’:’node_modules / @ ng-bootstrap / ng-bootstrap’添加到你的地图上.这将为您的ng-bootstrap提供一条路径.
>将’@ ng-bootstrap / ng-bootstrap’:{main:’index.js’,defaultExtension:’js’}添加到您的包中.
>添加一个提供所有ng-bootstrap组件文件夹的新数组(参见上面例子中的ngBootstrapPackageNames).
>现在通过将这些信息添加到地图中并将其与相应的索引文件相关联,将所有内容都集合到一起:
function ngBootstrapPackIndex(pkgName) { packages['@ng-bootstrap/ng-bootstrap/' + pkgName] = {main: 'index.js',defaultExtension: 'js'}; } ngBootstrapPackageNames.forEach(ngBootstrapPackIndex);
我希望这有助于,因为它适用于我的这些变化.
ng-bootstrap alpha 5的更新
如果您使用alpha 5,请将包变量中的@ ng-bootstrap / ng-bootstrap映射更改为此;
var packages = { ...,'@ng-bootstrap/ng-bootstrap': {main: '/bundles/ng-bootstrap.js',... }
