Angular(6) 的错误 TS2304：找不到名称“ICurrentWeatherData”

Question

When working with Angular6 the Error happens, though my app can be running and working properly, the tests will not pass. Here's the code snippet of the file:

`import { Injectable } from '@angular/core'
import { HttpClient } from '@angular/common/http'
import { Observable } from 'rxjs'
import { map } from 'rxjs/operators'
import { environment } from '../../environments/environment'
import { ICurrentWeather } from '../interfaces'

@Injectable()
export class WeatherService {
  constructor(private httpClient: HttpClient) {}

  getCurrentWeather(city: string, country: string): Observable<ICurrentWeather> {
    return this.httpClient
      .get<ICurrentWeatherData>(
        `${environment.baseUrl}api.openweathermap.org/data/2.5/weather?` +
          `q=${city},${country}&appid=${environment.appId}`
      )
      .pipe(map(data => this.transformToICurrentWeather(data)))
  }

  private transformToICurrentWeather(data: ICurrentWeatherData): ICurrentWeather {
    return {
      city: data.name,
      country: data.sys.country,
      date: data.dt * 1000,
      image: `http://openweathermap.org/img/w/${data.weather[0].icon}.png`,
      temperature: this.convertKelvinToFahrenheit(data.main.temp),
      description: data.weather[0].description,
    }
  }
  private convertKelvinToFahrenheit(kelvin: number): number {
    return (kelvin * 9) / 5 - 459.67
  }
}`

• ERROR in src/app/weather/weather.service.ts(14,12): error TS2304: Cannot find name 'ICurrentWeatherData'.

• src/app/weather/weather.service.ts(21,44): error TS2304: Cannot find name 'ICurrentWeatherData'.

Answer 1

您没有导入 ICurrentWeatherData，在接口导入中我只看到 ICurrentWeather

Answer 2

u should import that interface i thinks to that's works when u replace this :

import { ICurrentWeather } from '../interfaces'

to :

import { ICurrentWeather } from '../interfaces/ICurrentWeather'
