XMLHttpRequest未在platform-browser-dynamic.umd.js中定义
我得到一个XMLHttpRequest未定义与Angular2，Typescript和NodeJS的错误当我运行命令ts-node main.ts
这是我的例外
D:\workspace_git\nodejs\xgame\node_modules\@angular\platform-browser-dynamic\bundles\platform-browser-dynamic.umd.js:31 var xhr = new XMLHttpRequest(); ^ ReferenceError: XMLHttpRequest is not defined at ResourceLoaderImpl.get (D:\workspace_git\nodejs\xgame\node_modules\@angular\platform-browser-dynamic\bundles\platform-bro wser-dynamic.umd.js:31:27) at DirectiveNormalizer._fetch (D:\workspace_git\nodejs\xgame\node_modules\@angular\compiler\bundles\compiler.umd.js:13753:47 ) at DirectiveNormalizer.normalizeTemplateAsync (D:\workspace_git\nodejs\xgame\node_modules\@angular\compiler\bundles\compiler .umd.js:13799:25) at DirectiveNormalizer.normalizeTemplate (D:\workspace_git\nodejs\xgame\node_modules\@angular\compiler\bundles\compiler.umd. js:13771:48) at CompileMetadataResolver._loadDirectiveMetadata (D:\workspace_git\nodejs\xgame\node_modules\@angular\compiler\bundles\comp iler.umd.js:18074:79) at D:\workspace_git\nodejs\xgame\node_modules\@angular\compiler\bundles\compiler.umd.js:18250:58 at Array.forEach (native) at CompileMetadataResolver.loadNgModuleDirectiveAndPipeMetadata (D:\workspace_git\nodejs\xgame\node_modules\@angular\compile r\bundles\compiler.umd.js:18249:45) at D:\workspace_git\nodejs\xgame\node_modules\@angular\compiler\bundles\compiler.umd.js:27366:62 at Array.forEach (native) at JitCompiler._loadModules (D:\workspace_git\nodejs\xgame\node_modules\@angular\compiler\bundles\compiler.umd.js:27365:47) at JitCompiler._compileModuleAndComponents (D:\workspace_git\nodejs\xgame\node_modules\@angular\compiler\bundles\compiler.um d.js:27320:56) at JitCompiler.compileModuleAsync (D:\workspace_git\nodejs\xgame\node_modules\@angular\compiler\bundles\compiler.umd.js:2728 6:25) at PlatformRef_._bootstrapModuleWithZone (D:\workspace_git\nodejs\xgame\node_modules\@angular\core\bundles\core.umd.js:8083: 29) at PlatformRef_.bootstrapModule (D:\workspace_git\nodejs\xgame\node_modules\@angular\core\bundles\core.umd.js:8058:25)
