元素隐式具有'any'类型，因为类型的表达式

Question

这是我在limit-entries.ts中悬停在数据[command]上时遇到的完整错误

（参数）数据：dataProps元素隐式具有“ any”类型因为类型'“ hourly”'的表达式不能用于索引类型'dataProps'。类型“ dataProps”不存在属性“每小时”]
darkSkyApiTypes.ts

interface dataProps {
  data: {
    latitude: number
    longitude: number
    timezone: string
    currently?: {
      time: number
      summary: string
      temperature: number
      humidity: number
    }
    hourly?: {
      summary: string
      icon?: string
      data: {
        time: number
        temperature: number
        humidity: number
      }[]
    }
    daily?: {
      summary: string
      icon?: string
      data: {
        time: number
        temperatureMin: number
        temperatureMax: number
        humidity: number
      }[]
    }
  }
}

export = dataProps
limit-entries.ts

import { hourlyLimit } from '../config'
import dataProps from '../API/darkSkyAPITypes'

const limitEntries = (data: dataProps, command: string) => {
  let entries

  switch (command) {
    case 'currently':
      entries = data[command]
      break
    case 'hourly':
      entries = data[command].data.slice(0, hourlyLimit)
      break
    case 'daily':
      entries = data[command].data
      break
    default:
      entries = data[command]
  }

  return entries
}

module.exports = limitEntries
我得到标题错误。帮助！
