我收到此错误：

从天气导入天气，单位ImportError：无法导入名称 “天气”从“天气” （C：Users \ Python \ Python37 \ site-packages \ weather__init __。py）

我已使用pip安装了Weather，但仍然出现错误。我正在尝试安装weather-api，但没有找到weather-api的匹配发行版。

from weather import Weather,Unit
import time

class WeatherData:
temperature = 0
weather_conditions = ''
wind_speed = 0
city = ''

def __init__(self,city):
    self.city = city
    weather = Weather(unit = Unit.CELSIUS)
    lookup = weather.lookup_by_location(self.city)
    self.temperature = lookup.condition.temp
    self.weather_conditions = lookup.condition.text
    self.wind_speed = lookup.wind.speed

def getTemperature(self):
    return self.temperature + " C"

def getWeatherConditions(self):
    return self.weather_conditions

print(current_weather.getTemperature())
