模块导入对我不起作用。我尝试了堆栈溢出和其他提供的不同解决方案。这些是我遵循反应选择的步骤

npm install --save @types/react-select

像这样导入模块

import Select from "react-select"

但我得到了错误

找不到模块：错误：无法解析“react-select”

import * as React from "react";
import ReactSelect from 'react-select'
export class Select extends extends React.Component<someProps>{

render(){
   return(
  <Select id="color" options={options} />
);
}
}

但我找不到解决这个问题的方法。

当我要将数据绑定到全局变量时,我正在尝试从WebApi和Getting Undfind获取数据.

这是我的订阅

    export class OverallSummaryGaugeComponent implements OnInit {

  gaugeVal: any;
  bfd;
  pb: ProductionBreakDown[];
  gaugeSummaryType: String;
  constructor(private _sampleDataService: SampleDataObjectService, private _dashboard: DashboardService) { }
  customizeText(arg) {
    return arg.valueText + ' %';
  }

  ngOnInit() {
    this.gaugeVal = this._sampleDataService.CompletedPrasantage;
    this.getallData();
  }
  getallData() {
    this._dashboard.getProductionBreakDownByDate()
    .subscribe(pb => this.pb = pb
    );
    console.log(this.pb);
  }
}

当我改变代码时,就像它的打印数据一样.

this._dashboard.getProductionBreakDownByDate()
          .subscribe(pb => console.log(pb)
          );
          console.log(this.bd);
      }

但我试图将它绑定到获取未定义的相同类型的列表.

这是我的Observable代码

    @Injectable()
export class DashboardService extends BaseService {
    private _getProductionBreakDown = UrlsConfig.ptsapi + 'productionBreakDown/filterByDate/2018-12-17';
    constructor(private _dataAccessService: DataAccessService) {
        super(_dataAccessService);
    } …
