导读：我正在研究angular2“2.0.0-rc.1” 但是zoneJS给出了以下错误 Error: Uncaught (in promise): Expected 'styles' to be an array of strings. at resolvePromise (zone.js:538) at zone.js:515 at ZoneDelegate.invoke (zone.js:323) at Object.NgZoneImpl.i

我正在研究angular2“2.0.0-rc.1”
但是zoneJS给出了以下错误

Error: Uncaught (in promise): Expected 'styles' to be an array of strings.
    at resolvePromise (zone.js:538)
    at zone.js:515
    at ZoneDelegate.invoke (zone.js:323)
    at Object.NgZoneImpl.inner.inner.fork.onInvoke (eval at <anonymous> (vendor.js:335),<anonymous>:45:41)
    at ZoneDelegate.invoke (zone.js:322)
    at Zone.run (zone.js:216)

    at ZoneDelegate.invokeTask (zone.js:355)

我的代码如下

let styles   = require('./dashboard.css');
let template = require('./dashboard.html');
declare var zingchart:any;

@Component({
  selector: 'dashboard',directives: [ RouterLink,CORE_DIRECTIVES,FORM_DIRECTIVES ],template: template,styles: [ styles ]
})

解决方法

试试这个：
let styles = String(require(‘./ dashboard.css’));

它对我有用.由于样式需要字符串[],因此将样式解析为String().
