angular – 外部javascript库在'{module} / dist /’上返回4
|
在Angular2中配置外部项目总是遇到一些麻烦.
我想在我的项目中包含ng2-sharebuttons. (它似乎没有全局.d.ts文件？) 虽然README.md只是说npm install ng2-sharebuttons –save,但我知道还有更多内容(systemjs.config& typings) 首先,我尝试配置systemjs.config： map{
......
'ng2-sharebuttons' : 'node_modules/ng2-sharebuttons'
}
这至少修复了localhost / ng2-sharebuttons上的404,但在localhost / node_modules / ng2-sharebuttons上创建了一个新的404. 所以,我添加了一个主文件,将systemjs.config更改为 map{
......
'ng2-sharebuttons' : 'node_modules/ng2-sharebuttons/dist/index.js'
}
但是现在这导致ng2-sharebuttons / dist的每个孩子都有404 我尝试使用和不使用–global标志安装ng2-sharebuttons –save –global和typings install @ types / ng2-sharebuttons –save –global. 所以在我最后的希望中,我添加了一个参考,看看是否可行.添加 ///< reference path =“../../ node_modules / ng2-sharebuttons / dist / index.d.ts”/> 但这并没有改变任何事情. 我忘记了什么？为什么这么难？ (或者我只是努力吗？) 结构与ng2-sharebuttons文件：
最后,Chrome目前正在生成错误消息：
整个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

},// 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'
},firebase: {
main: './firebase-browser.js',defaultExtension: 'js'
}
}
});
})(this);
它抛出一个错误GET …. 404但也是一个XHR完成加载：GET ….在相同的组件/服务/文件,这似乎很奇怪. 解决方法
你需要这样做
map:{
'ng2-sharebuttons' : 'npm:ng2-sharebuttons/dist'
},packages: {
app: {main: './main.js',defaultExtension: 'js'},rxjs: {defaultExtension: 'js'},'ng2-sharebuttons': {main: 'index.js',defaultExtension: 'js'}
}
