Python 使用Firefox驱动程序在Ubuntu LTS上运行Headless Webdriver测试

我正在使用selenium 2.53.6版和firefox 46.0.1运行python 2.7.12。我的目标是在AWS Ubuntu服务器16.04 LTS上运行无头测试。我就是这样设置的

# install anaconda
cd ~
wget https://repo.continuum.io/archive/Anaconda2-4.2.0-Linux-x86_64.sh
bash Anaconda2-4.2.0-Linux-x86_64.sh
rm Anaconda2-4.2.0-Linux-x86_64.sh
echo export 'PATH="/home/ubuntu/anaconda2/bin:$PATH"' >> ~/.bashrc
source .bashrc
conda update conda

# install firefox version 46.0.1
wget https://ftp.mozilla.org/pub/firefox/releases/46.0.1/linux-x86_64/en-US/firefox-46.0.1.tar.bz2
tar jxf firefox-46.0.1.tar.bz2
rm firefox-46.0.1.tar.bz2

# install pyvirtualdisplay
sudo apt-get install xvfb xserver-xephyr
pip install pyvirtualdisplay

# install selenium version 2.53.6
pip install selenium==2.53.6

当我运行此代码时

from pyvirtualdisplay import Display
from selenium import webdriver

display = Display(visible=0, size=(1024, 768))
display.start()

browser = webdriver.Firefox()
driver.get("http://www.python.org")

driver.quit()
display.stop()

我得到这个错误：

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/ubuntu/anaconda2/lib/python2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 55, in __init__
self.binary = firefox_binary or capabilities.get("binary",  FirefoxBinary())
File "/home/ubuntu/anaconda2/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 47, in __init__
self._start_cmd = self._get_firefox_start_cmd()
File "/home/ubuntu/anaconda2/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 163, in _get_firefox_start_cmd
" Please specify the firefox binary location or install firefox")
RuntimeError: Could not find firefox in your system PATH. Please specify the firefox binary location or install firefox

鉴于我已经在使用pyvirtualdisplay，有人知道解决方案吗

根据我的理解，Firefox不是为无头机制而构建的[如果我错了，请纠正我]。

您可以使用更好的处理。

据我所知，Firefox不是为无头机制而构建的[如果我错了，请纠正我]。 你可以用它来更好地操控

"The browser appears to have exited "
selenium.common.exceptions.WebDriverException: Message: The browser    appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.
