通过查看here 帖子成功安装 chrome 驱动程序后，我正在尝试创建 chrome 驱动程序实例。如帖子所示，我为 python 下载了chrome-driver 64-bit。我将chromedriver可执行文件移动到/usr/bin，并尝试了以下代码

 from selenium import webdriver
 driver = webdriver.Chromedriver()

结果：

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

/home/local/user/<ipython console> in <module>()

AttributeError: 'module' object has no attribute 'Chromedriver'

也尝试以下方法时

 from selenium import webdriver
 driver = webdriver.Firefox()

结果：

WebDriverException                        Traceback (most recent call last)

/home/local/<ipython console> in <module>()

/usr/lib/python2.7/site-packages/selenium-2.21.3-py2.7.egg/selenium/webdriver/firefox/webdriver.pyc in __init__(self, firefox_profile, firefox_binary, timeout)

     79                 raise WebDriverException("The browser appears to have exited "
     80                       "before we could connect. The output was: %s" %
---> 81                       self._get_firefox_output())
     82             if count == 30:
     83                 self.kill()

WebDriverException: Message: 'The browser appears to have exited before we could connect. The output was: *** LOG addons.xpi: startup\n*** LOG addons.xpi: checkForChanges\n*** LOG addons.xpi: Opening database\n*** LOG addons.xpi: No changes found\nFailed to dlopen /usr/lib/libX11.so.6\ndlerror says: /usr/lib/libX11.so.6: wrong ELF class: ELFCLASS32\n'

我不知道这里发生了什么，以及为什么 chrome 和 firefox 网络驱动程序都不起作用。

【问题讨论】：

标签： python selenium webdriver

【解决方案1】：

它的webdriver.Chrome() 不是 webdriver.Chromedriver()

您可以通过将可执行文件的路径指定为参数来避免复制 /usr/bin ..etc 中的可执行文件

webdriver.Chrome(executable_path='...')

这样您就可以避免一个额外的步骤，并将驱动程序签入您的源代码控制目录等。
