ある
：ここでは4.2.2は私のシステム-config.ts
const map: any = {
};
/** User packages configuration. */
const packages: any = {
};
const barrels: string[] = [
// Angular specific barrels.
'@angular/core',
'@angular/common',
'@angular/compiler',
'@angular/http',
'@angular/router',
'@angular/platform-browser',
'@angular/platform-browser-dynamic',

'rxjs',
// App specific barrels.
'app',
'app/shared',
'app/tree',
'app/tree/item',
/** @cli-barrel */
];
const cliSystemConfigPackages: any = {};
barrels.forEach((barrelName: string) => {
cliSystemConfigPackages[barrelName] = { main: 'index' };
});
/** Type declaration for ambient System. */
declare var System: any;
// Apply the CLI SystemJS configuration.
System.config({
map: {

'rxjs': 'vendor/rxjs',

},
packages: cliSystemConfigPackages
});
// Apply the user's configuration.
System.config({ map, packages });
