python中的pyvirtualdisplay错误

Question

当我尝试运行python代码File_1.py实际导入File_2.py来调用函数时，我得到了以下错误。

Traceback (most recent call last):
File "File_1.py", line 1, in <module>
import File_2
File "/home/eduser/shashank/File_2.py", line 8, in <module>
display = Display(visible=0, size=(800, 600))
File "/usr/local/lib/python2.7/dist-packages/pyvirtualdisplay/display.py", 
line 34, in __init__
self._obj = self.display_class(
File "/usr/local/lib/python2.7/dist-packages/pyvirtualdisplay/display.py", 
line 52, in display_class
cls.check_installed()
File "/usr/local/lib/python2.7/dist-packages/pyvirtualdisplay/xvfb.py", line 
38, in check_installed
ubuntu_package=PACKAGE).check_installed()
File "/usr/local/lib/python2.7/dist-packages/easyprocess/__init__.py", line 
180, in check_installed
raise EasyProcessCheckInstalledError(self)
easyprocess.EasyProcessCheckInstalledError: cmd=['Xvfb', '-help']
OSError=None
Program install error!

下面是错误所指向的代码部分

import time
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import File_3_1

from pyvirtualdisplay import Display

display = Display(visible=0, size=(800, 600))
display.start()

任何帮助都将不胜感激。

您可能只需要安装xvfv。尝试：

sudo apt-get install xvfb xserver-xephyr vnc4server
