Question

我尝试了许多指定路径的变体，以允许SystemJS加载ngx-bootstrap包

    System.config({
    "defaultJSExtensions": true,
    "paths": {

        "@angular/core": "node_modules/@angular/core/bundles/core.umd.js",
        "@angular/forms": "node_modules/@angular/forms/bundles/forms.umd.js",
        "@angular/http": "node_modules/@angular/http/bundles/http.umd.js",
        ...
        "*": "node_modules/*",
        "ngx-bootstrap": "node_modules/ngx-bootstrap",
        "highcharts": "node_modules/highcharts/highcharts.js",
        "angular2-highcharts": "node_modules/angular2-highcharts/index.js"
    },
    "packages": {}
});

但它仍然无法正常加载..

我在控制台中看到以下错误

"(SystemJS) XHR error (404 Not Found) loading http://localhost:5555/node_modules/ngx-bootstrap.js 

wrapFn@http://localhost:5555/node_modules/zone.js/dist/zone.js?1493823577322:1230:30 [<root>]       

Error loading http://localhost:5555/node_modules/ngx-bootstrap.js as "ngx-bootstrap" from http://localhost:5555/hc/app.module.js" 

"Not expecting this error? Report it at https://github.com/mgechev/angular-seed/issues"

你错过了这一部分：

packages: {
  //... other code
  'ngx-bootstrap': { format: 'cjs', main: 'bundles/ngx-bootstrap.umd.js', defaultExtension: 'js' },
}
