Python 2.7-使用Xvfb进行Selenium无头测试无法正常工作 [英] Python 2.7 - Selenium headless testing with Xvfb not working

问题描述

请注意，我已经查看了以下来源:

Note I have already looked at the following sources:

easyprocess.EasyProcessCheckInstalledError:cmd = ['Xvfb'，'- help'] OSError = [Errno 2]没有这样的文件或目录

如何在Xvfb中运行Selenium?

哪个没有解决我的问题.

Which did not solve my problem.

我正在使用:

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

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

Running on Mac OSX El Capitan (10.11.6 (15G1108))

我收到以下错误(与上面的链接中的错误相同):

I get the following error (which is the same one that is in the above link):

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:

I know I have Xvfb installed as well:

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

...

如果pip安装正在其他目录中寻找xvfb，则将对如何将其重定向到所寻找的位置提供一些指导.

If the pip install is looking for xvfb in a different directory, some guidance would be appreciated as to how to redirect where it's looking.

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()

我已经完成了无数的pip安装和google搜索，但到目前为止没有任何帮助，最终的最终目标是拥有能够处理下载的无头自动化，这是PhantomJS无法做到的.在该主题上的任何帮助也将不胜感激.

I've done countless pip installs and google searches and nothing has helped so far, the ultimate end goal is to have a headless automation that is capable of handling downloads, something PhantomJS is unable to do. Any help in that subject would be appreciated as well.

推荐答案

我看不到为什么不能在osx中​​使用它，我过去已经做到了.但是我有一个更好的解决方案.为什么不使用 docker +

I dont see why you cant use this with osx, I have done that in past. But I have a better solution. Why dont you use docker + VNC . install any browser of your choice and run everything in the background Advantage: 1. Everything runs in the background. 2. Monitor execution in the browser with VNC web view 3. launch as many container as you want for parallel execution.
