我试图使用 Selenium 运行 headless Chrome 浏览器来从网络上抓取内容。我使用 wget 安装了 headless Chrome,然后在我当前的文件夹中解压。

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

现在当我加载驱动程序时
from selenium.webdriver.chrome.options import Options
import os
# instantiate a chrome options object so you can set the size and headless preference
chrome_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)

我收到一个错误
WebDriverException                        Traceback (most recent call last)
<ipython-input-67-0aeae0cfd891> in <module>()

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

更新

所以经过一些研究,我尝试了另一种方式
!apt install chromium-chromedriver
import selenium as se

options = se.webdriver.ChromeOptions()
options.add_argument('headless')

driver = se.webdriver.Chrome(chrome_options=options)

在 Google Colab 上,它再次给了我同样的错误
WebDriverException: Message: Service chromedriver unexpectedly exited. Status code was: -6

最佳答案

我找到了关于为什么我收到错误的问题的答案。请安装chromium-chromedriver并将其添加到您的路径变量以及bin目录中。

这是如何在 Colab 上使用 Selenium 抓取数据的问题的成熟解决方案。还有一种使用 PhantomJS 的方法,但是这个 API 已经被 Selenium 弃用了,希望他们会在下一个 Selenium 更新中删除它。

# 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 webdriver
options = 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 results
wd = webdriver.Chrome('chromedriver',options=options)
wd.get("https://www.website.com")
print(wd.page_source)  # results

这适用于想要在 Google Colab 上而不是在您的本地机器上抓取数据的任何人。请按相同顺序依次执行所示步骤。
