如何让硒和铬在 ubuntu 上工作

Question

我正在尝试将 selenium 与 Chrome 结合使用来浏览使用 javascript.

的网站

我安装了：

铬：
```
sudo apt-get install chromium-browser
```
chrome 驱动程序，从 https://sites.google.com/a/chromium.org/chromedriver/downloads
硒
```
pip install selenium
```

但是，我无法完成这项工作：

from selenium import webdriver

service_args = ['--verbose']
service_log_path = "{}/chromedriver.log".format('/projects/')

driver = webdriver.Chrome('/path/to/chromedriver', service_args=service_args, service_log_path=service_log_path)

我收到这个错误：

WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
  (Driver info: chromedriver=2.13.307649 (bf55b442bb6b5c923249dd7870d6a107678bfbb6),platform=Linux 3.13.0-30-generic x86_64)

这是我的日志文件：什么是开发工具问题？

您可以在虚拟显示器上使用 Xvfb with the help of pyvirtualdisplay 到运行您的 chrome 自动化，因为您没有真实的显示器：

from pyvirtualdisplay import Display
from selenium import webdriver

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

browser = webdriver.Chrome()
browser.get('http://www.google.com')
print browser.title
browser.quit()

display.stop()

另请参阅：

How do I run Selenium in Xvfb?

除此之外，切换到 PhantomJS 也是一种选择：

from selenium import webdriver

browser = webdriver.PhantomJS()
browser.get('http://www.google.com')
print browser.title
browser.quit()
