我已經(jīng)找到了有關(guān)為什么我出錯的問題的答案。請安裝chrome-chromedriver，并將其添加到您的路徑變量以及bin目錄中。

這是解決如何在Colab上使用Selenium抓取數(shù)據(jù)的完整解決方案。使用PhantomJS還有另一種方法，但是Selenium已棄用此API，希望他們在下一次Selenium更新中將其刪除。

# install chromium, its driver, and selenium!apt-get update!apt install chromium-chromedriver!cp /usr/lib/chromium-browser/chromedriver /usr/bin!pip install selenium# set options to be headless, ..from selenium import webdriveroptions = webdriver.ChromeOptions()options.add_argument(’--headless’)options.add_argument(’--no-sandBox’)options.add_argument(’--disable-dev-shm-usage’)# open it, go to a website, and get resultswd = webdriver.Chrome(’chromedriver’,options=options)wd.get('https://www.website.com')print(wd.page_source) # results

這對于想要在Google Colab上而不是在您的本地計算機上抓取數(shù)據(jù)的任何人都有效。請按相同順序依次執(zhí)行以下步驟。

解決方法

我試圖使用Selenium運行無頭Chrome瀏覽器以從網(wǎng)絡(luò)上抓取內(nèi)容。我使用wget安裝了無頭Chrome，然后將其解壓縮到當前文件夾中。

!wget 'http://chromedriver.storage.googleapis.com/2.25/chromedriver_linux64.zip'!unzip chromedriver_linux64.zip

現(xiàn)在，當我加載驅(qū)動程序時

from selenium.webdriver.chrome.options import Optionsimport os# instantiate a chrome options object so you can set the size and headless preferencechrome_options = Options()chrome_options.add_argument('--headless')chrome_options.add_argument('--window-size=1920x1080')chrome_driver = os.getcwd() +'/chromedriver'driver = webdriver.Chrome(chrome_options=chrome_options,executable_path=chrome_driver)

我收到一個錯誤

WebDriverExceptionTraceback (most recent call last)<ipython-input-67-0aeae0cfd891> in <module>()----> 1 driver = webdriver.Chrome(chrome_options=chrome_options,executable_path=chrome_driver) 2 driver.get('https://www.google.com') 3 lucky_button = driver.find_element_by_css_selector('[name=btnI]') 4 lucky_button.click() 5 /usr/local/lib/python3.6/dist-packages/selenium/webdriver/chrome/webdriver.py in __init__(self,executable_path,port,chrome_options,service_args,desired_capabilities,service_log_path) 60 service_args=service_args,61 log_path=service_log_path)---> 62 self.service.start() 63 64 try: /usr/local/lib/python3.6/dist-packages/selenium/webdriver/common/service.py in start(self) 84 count = 0 85 while True: ---> 86 self.assert_process_still_running() 87 if self.is_connectable(): 88 break /usr/local/lib/python3.6/dist-packages/selenium/webdriver/common/service.py in assert_process_still_running(self) 97 raise WebDriverException( 98 ’Service %s unexpectedly exited.

因此，經(jīng)過一些研究，我嘗試了另一種方法

!apt install chromium-chromedriverimport selenium as seoptions = se.webdriver.ChromeOptions()options.add_argument(’headless’)driver = se.webdriver.Chrome(chrome_options=options)

在Google Colab上，這再次給了我相同的錯誤

WebDriverException: Message: Service chromedriver unexpectedly exited. Status code was: -6
