chromedriver 的 python-selenium 绑定错误 [英] Error in python-selenium bindings for chromedriver

问题描述

通过查看帖子此处.如帖子中所示，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

I am trying to create an instance of chrome driver after installing chrome driver successfully by seeing the post here. As shown in the post i downloaded chrome-driver 64-bit for python. And i moved the chromedriver executable file to /usr/bin, and tried the following code

 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'

也当尝试以下

 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" %
---> 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.

I am unable know whats happening here, and why both chrome and firefox web drivers are not working.

推荐答案

its webdriver.Chrome() not 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

and you can avoid copying the executable in /usr/bin ..etc by specifying the path to the executable as an argument

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

这样您就可以避免一个额外的步骤，并且还可以将驱动程序签入您的源代码控制目录等.

that way you can avoid one extra step and also have the driver checked into your source control directory etc.
