Python 2.7 - 使用Xvfb的Selenium无头测试不起作用

标签: macos python-2.7 selenium-webdriver

注意我已经查看过以下来源:

easyprocess.EasyProcessCheckInstalledError: cmd=['Xvfb', '-help'] OSError=[Errno 2] No such file or directory

How do I run Selenium in Xvfb?

哪个没解决我的问题。

我正在使用:

  • Python 2.7
  • selenium 3.0.2
  • xvfbwrapper 0.2.9
  • PyVirtualDisplay 0.2.1

在Mac OSX El Capitan上运行(10.11.6(15G1108))

我收到以下错误(与上述链接中的错误相同):

Traceback (most recent call last):
  File "/Users/user/Desktop/test.py", line 50, in <module>
    display = Display(visible=0, size=(800, 600))
  File "/Library/Python/2.7/site-packages/pyvirtualdisplay/display.py", line 34, in __init__
    self._obj = self.display_class(
  File "/Library/Python/2.7/site-packages/pyvirtualdisplay/display.py", line 52, in display_class
    cls.check_installed()
  File "/Library/Python/2.7/site-packages/pyvirtualdisplay/xvfb.py", line 38, in check_installed
    ubuntu_package=PACKAGE).check_installed()
  File "/Library/Python/2.7/site-packages/easyprocess/__init__.py", line 180, in check_installed
    raise EasyProcessCheckInstalledError(self)
EasyProcessCheckInstalledError: cmd=['Xvfb', '-help']
OSError=[Errno 2] No such file or directory
Program install error! 

我知道我也安装了Xvfb:

Xvfb -help
use: X [:<display>] [option]
-a #                   default pointer acceleration (factor)
-ac                    disable access control restrictions
-audit int             set audit trail level
-auth file             select authorization file
-br                    create root window with black background
+bs                    enable any backing store support
-bs                    disable any backing store support
-c                     turns off key-click
...
-pixdepths list-of-int support given pixmap depths
+/-render          turn on/off RENDER extension support(default on)
-linebias n            adjust thin line pixelization
-blackpixel n          pixel value for black
-whitepixel n          pixel value for white
-fbdir directory       put framebuffers in mmap'ed files in directory
-shmem                 put framebuffers in shared memory

如果pip install正在寻找不同目录中的xvfb,那么可以理解一些指导如何重定向它所在的位置。

这是我的代码:

from easyprocess import EasyProcess
from pyvirtualdisplay import Display
from selenium import webdriver

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

# now Firefox will run in a virtual display. 
# you will not see the browser.
browser = webdriver.Firefox()
browser.get('http://www.google.com')
print browser.title
browser.quit()

display.stop()

我做了无数的pip安装和谷歌搜索,到目前为止没有任何帮助,最终的目标是拥有一个能够处理下载的无头自动化,这是PhantomJS无法做到的。任何有关该主题的帮助也将受到赞赏。

我不明白为什么你不能用这个用osx,我过去做过。但我有一个更好的解决方案。为什么不使用docker + VNC。安装您选择的任何浏览器并在后台运行所有内容 优点: 1.一切都在后台运行。 2.使用VNC Web视图监视浏览器中的执行情况 3.根据需要启动并行执行的容器。
