Question

我们正在与我的朋友一起在学校项目中使用python。我们的工作是从流行的汽车销售网站（http://otomoto.pl）进行一些网页抓取，并生成有关此主题的一些图表。我正在使用VS 2017，而朋友正在使用VS Code。我们都有通过github共享的相同代码，如下所示：

import requests
from lxml import html
from Models.Car import *

class DataPicker():

    url = 'https://www.otomoto.pl/osobowe/?page='
    htmlElement = ""
    pageQuantity = 40
    articlesPerSite = 32

    def main(self):
            for pageNumber in range(1, self.pageQuantity):
                    self.setHtmlElementByPage(pageNumber)
                    for article in range(1, self.articlesPerSite):
                            model = self.getModel(article)
                            year = self.getYear(article)
                            mileage =self.getMileage(article)
                            price = self.getPrice(article)
                            singleCarModel = Car(model, year, mileage, price)
                            print(self.showCarProperties(singleCarModel))

    def getModel(self, articleNumber):
            model = self.htmlElement.xpath("/html/body/div[4]/div[2]/section/div[2]/div[1]/div/div[1]/div[5]/article[" + str(articleNumber) + "]/div[2]/div[1]/h2/a/text()")
            return model[0]

    def getYear(self, articleNumber):
            year = self.htmlElement.xpath("/html/body/div[4]/div[2]/section/div[2]/div[1]/div/div[1]/div[5]/article[" + str(articleNumber) + "]/div[2]/ul/li[1]/span/text()")
            return year[0]

    def getMileage(self, articleNumber):
            mileage = self.htmlElement.xpath("/html/body/div[4]/div[2]/section/div[2]/div[1]/div/div[1]/div[5]/article[" + str(articleNumber) + "]/div[2]/ul/li[2]/span/text()")
            return mileage[0]

    def getPrice(self, articleNumber):
            price = self.htmlElement.xpath("/html/body/div[4]/div[2]/section/div[2]/div[1]/div/div[1]/div[5]/article[" + str(articleNumber) + "]/div[2]/div[2]/div/span[1]/text()")
            return price[0]

    def setHtmlElementByPage(self, pageNumber):
            currentUrl = self.url + str(pageNumber)
            page = requests.get(currentUrl)
            self.htmlElement = html.fromstring(page.content)

    def showCarProperties(self, singleCarModel):
            return "Model : " + str(singleCarModel.model) + "\nYear : " + str(singleCarModel.year) + "\nMileage : " + str(singleCarModel.mileage) + "\nPrice : " + str(singleCarModel.price) + "\n\n"

if __name__ == '__main__':
DataPicker().main()

虽然在朋友的VSC下一切正常，但我不断收到错误消息： 从lxml导入html-DLL加载失败：找不到模块

我尝试通过pip再次卸载和安装lxml，但是没有任何变化。我在这里做错什么了吗，还是我丢失了一些文件？

错误日志：
