Question

我正在尝试通过查看帖子here成功安装Chrome驱动程序后创建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'

同时尝试以下

 from selenium import webdriver
 driver = webdriver.Firefox()

结果：

WebDriverException                        Traceback (most recent call last)

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

     80                       "before we could connect. The output was: %s" %

     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'

我无法知道这里发生了什么，以及为什么chrome和firefox网络驱动程序都无法正常工作。

Answer 1

其webdriver.Chrome() 不 webdriver.Chromedriver()

并且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='...')

这样你可以避免一个额外的步骤，并将驱动程序检入你的源代码管理目录等。

chromedriver的python-selenium绑定错误
