chromedriver的python-selenium綁定錯誤

Question

我正在嘗試通過查看此處的帖子成功安裝chrome驅動程序后創建chrome驅動程序的實例。 如帖子所示，我為python下載了chrome-driver 64-bit 。 我將chromedriver可執行文件移動到/usr/bin ，並嘗試了以下代碼

 from selenium import webdriver
 driver = webdriver.Chromedriver()

結果 ：

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

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

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

也嘗試以下時

 from selenium import webdriver
 driver = webdriver.Firefox()

結果：

WebDriverException                        Traceback (most recent call last)

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

     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' 

我不知道這里發生了什么，以及為什么chrome和firefox web驅動程序都無法正常工作。

Answer 1

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

並且您可以通過將可執行文件的路徑指定為參數來避免復制/ usr / bin ..etc中的可執行文件

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

這樣你可以避免一個額外的步驟，並將驅動程序檢入您的源控制目錄等。
