意外的令牌导入运行节点server.js
我试图做Angular通用快速入门，并得到这个错误，当我运行“节点server.js”。
Benjamins-MBP:vepo Ben$ node server.js /Users/Ben/Development/vepo/server.js:3 import 'angular2-universal/polyfills'; ^^^^^^ SyntaxError: Unexpected token import at Object.exports.runInThisContext (vm.js:76:16) at Module._compile (module.js:542:28) at Object.Module._extensions..js (module.js:579:10) at Module.load (module.js:487:32) at tryModuleLoad (module.js:446:12) at Function.Module._load (module.js:438:3) at Module.runMain (module.js:604:10) at run (bootstrap_node.js:394:7) at startup (bootstrap_node.js:149:9) at bootstrap_node.js:509:3 Benjamins-MBP:vepo Ben$ 我正在添加通用到现有的angular2应用程序。
我如何摆脱错误？
编辑：我运行npm安装时遇到了一些错误：
Benjamins-MBP:vepo Ben$ sudo npm install body-parser angular2-universal preboot express --save Password: vepo@1.0.0 /Users/Ben/Development/vepo ├── angular2-universal@2.1.0-rc.1 ├── body-parser@1.15.2 ├── express@4.14.0 ├── preboot@4.5.2 └── UNMET PEER DEPENDENCY tslint@4.0.2 invalid
和

我改变它，但它是抛出错误：
require('angular2-universal/polyfills'); require ('path'); require ('express'); // Angular 2 Universal require ('@angular/router/provideRouter'); require ('@angular/core/enableProdMode'); require ('angular2-universal/*'); // replace this line with your Angular 2 root component require ('./app/AppModule'); require ('./app/app.routes/*')
错误：

使用require而不是import 。
因为他们还没有实施。
节点使用完成了大部分ES6function的V8版本。 不幸的是，模块不是那些完成的function之一。
对于你的types安装使用“dt〜”前缀
例如：typings install –save –global dt〜node
