IE和Chrome无法使用Selenium2 Python(IE and Chrome not working with Selenium2 Python)

 我似乎无法通过Selenium 2的Python库打开谷歌浏览器或Internet Explorer。 我使用的是Windows 7,64位。  
 我已完成以下步骤：  
 
  已安装的python - 2.7.5  
  安装硒2.33  
  在环境变量 - 路径中包含C：\ Python27＆C：\ Python27 \ Scripts  
  下载32位（我正在运行64位但我找不到32位版本）windows Chrome驱动程序支持v27-30（我28岁）并将其放入C：\ Python27 \ Scripts  
  下载支持IE9的64位IE驱动程序（我将IE10降级为IE9）。 我将驱动程序放入C：\ Python27 \ Scripts  
 
 每当我打字：  
from selenium import webdriver
driver = webdriver.Ie()
 
 要么  
from selenium import webdriver
driver = webdriver.Chrome()
 
 进入Python shell，没有浏览器弹出，shell只会冻结几分钟然后输出错误信息。  
 IE错误消息：  
selenium.common.exceptions.WebDriverException: Message: 'Can not connect to the IEDriver'
 
 Chrome错误消息：  
urllib2.HTTPError: HTTP Error 503: Service Unavailable
 
 它与firefox完美搭配。 有趣的是，该过程（IEDriver和ChromeDriver）是根据TaskManager启动的，但窗口永远不会出现。 

I can't seem to open up Google Chrome or Internet Explorer through Selenium 2's Python library. I am using Windows 7, 64 bit. 
I have completed the following steps: 
 
 Installed python - 2.7.5 
 Installed selenium 2.33  
 Included C:\Python27 & C:\Python27\Scripts in the Environment Variable - Path 
 Downloaded the 32 bit (I am running 64 bit but I could not find the 32 bit version) windows Chrome Driver that supports v27-30 (I am on 28) and placed it into C:\Python27\Scripts  
 Downloaded the 64 bit IE driver that supports up to IE9 (I downgraded IE10 to IE9). I placed the driver into C:\Python27\Scripts 
 
Whenever I type: 
from selenium import webdriver
driver = webdriver.Ie()
 
OR 
from selenium import webdriver
driver = webdriver.Chrome()
 
into the Python shell, no browser pops up, the shell just freezes for a couple of minutes and then outputs an error message.  
IE Error message: 
selenium.common.exceptions.WebDriverException: Message: 'Can not connect to the IEDriver'
 
Chrome Error message: 
urllib2.HTTPError: HTTP Error 503: Service Unavailable
 
It works perfectly fine with firefox. The funny thing is, is that the process (IEDriver and ChromeDriver) starts per the TaskManager, but the window never shows up.

 在python-selenium webdriver.Ie只是执行IEDriver.exe并通过webdriver.Remote连接到它的快捷方式。 例如，您可以从命令行启动IEDriver.exe ：  
> IEDriverServer.exe
Started InternetExplorerDriver server (64-bit)
2.39.0.0
Listening on port 5555
 
 并使用以下代码替换webdriver.Ie() ：  
webdriver.Remote(command_executor='http://127.0.0.1:5555',
                 desired_capabilities=DesiredCapabilities.INTERNETEXPLORER)`
 
 你会得到相同的结果。  
 特别是在您的情况下，您很可能有一些系统代理设置强制它通过代理服务器连接到127.0.0.1 。 可能当您按照回答Python中的描述禁用它时：在urllib2中禁用http_proxy ，您可以解决问题：  
import selenium
import urllib2
from contextlib import contextmanager

@contextmanager
def no_proxies():
    orig_getproxies = urllib2.getproxies
    urllib2.getproxies = lambda: {}
    yield
    urllib2.getproxies = orig_getproxies

with no_proxies():
    driver = selenium.webdriver.Ie()
    driver.get("http://google.com")

In python-selenium webdriver.Ie is just a shortcut for executing IEDriver.exe and connecting to it through webdriver.Remote. For example, you could start IEDriver.exe from command line: 
> IEDriverServer.exe
Started InternetExplorerDriver server (64-bit)
2.39.0.0
Listening on port 5555
 
and replace webdriver.Ie() with the following code: 
webdriver.Remote(command_executor='http://127.0.0.1:5555',
                 desired_capabilities=DesiredCapabilities.INTERNETEXPLORER)`
 
You will get the same result. 
Specifically in your case is most likely that you have some system proxy settings that force it connect to 127.0.0.1 through proxy server. Probably when you disable it as described in answer Python: Disable http_proxy in urllib2, you can solve the problem: 
import selenium
import urllib2
from contextlib import contextmanager

@contextmanager
def no_proxies():
    orig_getproxies = urllib2.getproxies
    urllib2.getproxies = lambda: {}
    yield
    urllib2.getproxies = orig_getproxies

with no_proxies():
    driver = selenium.webdriver.Ie()
    driver.get("http://google.com")
