Question

我试图使用python webdriver在linux中获取html源代码。

但是我得到了以下错误：

python daiwa.py 'http://asp.hotel-story.ne.jp/ver3d/planlist.asp?herehcod1=DWHQ0&sAreacode=00151&hidmode=select&mode=seek&hidSELECTARRYMD=2016/06/22&hidSELECTadult=1'Traceback (most recent call last):

raise EasyProcessCheckInstalledError(self)
easyprocess.EasyProcessCheckInstalledError: cmd=['Xephyr', '-help']
OSError=[Errno 2] No such file or directory
Program install error!

有人可以帮助我吗？

版本：python - ＆gt; 2.7.9 这是我的代码。

#-*- coding: utf-8 -*-
from pyvirtualdisplay import Display
from selenium import webdriver

xephyr=Display(visible=1, size=(320, 240)).start()

path_to_chromedriver = "/usr/local/bin/chromedriver"

templete = webdriver.Chrome("/usr/local/bin/chromedriver")
templete.get("https://asp.hotel-story.ne.jp/ver3d/planlist.asp?hcod1=DWHQ0&hcod2=001&hidmode=select&mode=seek&hidSELECTARRYMD=2016/6/25&hidSELECTHAKSU=1&room=1&hidSELECTadult=1&hidSELECTchilda=0&hidSELECTchildb=0&hidSELECTchildc=0&hidSELECTchildd=0&hidSELECTminPrice=0&hidSELECTmaxPrice=9999999&Dispunit=&chkymd=0&chkpsn=0&sAreacode=00101")

templete.find_element_by_xpath("//select[@id='seekCount']/option[@value='9999']").click()

html_source = templete.page_source

if isinstance(html_source, unicode):
    html_source = html_source.encode('UTF-8')

print html_source

templete.close()

在您的代码更改行

中

xephyr=Display(visible=1, size=(320, 240)).start()

到

xephyr=Display(visible=0, size=(320, 240)).start()  # visible=0

如果后端 Xephyr：：

display = Display(visible=1, size=(320, 240)).start()  # visible=1

如果后端 Xvfb：

display = Display(visible=0, size=(320, 240)).start()  # visible=0

Python OSError：[Errno 2]没有这样的文件错误
