帮助: cmd=['Xephyr'，‘-EasyProcessCheckInstalledError’]

Question

我在Windows7 SP1上使用Python2.7，并且已经正确安装了pyvirtualdisplay和Selenium，但是当我运行这个脚本时：

from pyvirtualdisplay import Display
display = Display(visible=1, size=(800, 600))
display.start()

我得到了这个错误：

Traceback (most recent call last):
  File "C:\Python27\hoho - Copie.py", line 2, in <module>
    display = Display(visible=1, size=(800, 600))
  File "build\bdist.win32\egg\pyvirtualdisplay\display.py", line 34, in __init__
    self._obj = self.display_class(
  File "build\bdist.win32\egg\pyvirtualdisplay\display.py", line 52, in display_class
    cls.check_installed()
  File "build\bdist.win32\egg\pyvirtualdisplay\xephyr.py", line 30, in check_installed
    ubuntu_package=PACKAGE).check_installed()
  File "build\bdist.win32\egg\easyprocess\__init__.py", line 180, in check_installed
    raise EasyProcessCheckInstalledError(self)

我找到了解决这个问题的方法，下载chromedriver.exe并将其复制到path文件夹中，然后更改以下代码：

from pyvirtualdisplay import Display
display = Display(visible=1, size=(800, 600))
display.start()

至

from selenium import webdriver
chrome_path = r"C:\Python27\chromedriver.exe"
driver = webdriver.Chrome(chrome_path)
