WebDriverException：消息：未知錯誤：Chrome 無法啟動：使用 ChromeDriver Chrome 和 Selenium Python 異常退出錯誤

Question

我正在嘗試在我的虛擬 ubuntu shell 上安裝和使用 Selenium chromedriver，我一步一步地按照各種教程進行操作，但似乎仍有問題......經過對該問題的多次研究后，我找不到任何答案。

這是我試圖運行的小代碼：

from selenium import webdriver
from selenium.webdriver import Chrome
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-extensions')
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get('https://google.com')

由於我在各種主題上找到的建議，我添加了 chrome_options。 但是我真的不明白為什么有必要？

不幸的是，我的程序向我發送了以下錯誤，我在這里卡住了，我不知道該怎么辦：

  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /usr/bin/chromium-browser is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

有人已經遇到過這個問題或對此有任何建議嗎？

第一條錯誤信息...

/home/lclis/anaconda3/lib/python3.7/site-packages/ipykernel_launcher.py:7: DeprecationWarning: use options instead of chrome_options
  import sys
---------------------------------------------------------------------------
WebDriverException                        Traceback (most recent call last)
<ipython-input-4-259faa721232> in <module>
      5 chrome_options.add_argument('--no-sandbox')
      6 chrome_options.add_argument('--disable-extensions')
----> 7 driver = webdriver.Chrome(chrome_options=chrome_options)

...暗示ChromeDriver無法啟動/生成新的瀏覽上下文，即Chrome 瀏覽器會話。

---

根據Selenium的python客戶端v3.8.0 chrome_options的發行說明已棄用：

瀏覽器選項參數現在作為options跨驅動程序標准化。 firefox_options 、 chrome_options和ie_options現已棄用。

解決方案

在初始化 ChromeDriver/Chrome 會話時，您需要使用options而不是chrome_options 。 所以有效地你的代碼塊將是：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-extensions')
driver = webdriver.Chrome(executable_path='/path/to/chromedriver', options=chrome_options)
driver.get('https://google.com')

Answer 2

您可以使用以下代碼片段在服務器（沒有 GUI 的ubuntu，框中沒有可用的X 窗口）上運行selenium爬蟲：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')

driver = webdriver.Chrome(executable_path='/usr/lib/chromium-browser/chromedriver', options=chrome_options)
driver.get('https://google.com')

Answer 3

我在谷歌上搜索 ruby​​ 錯誤，但發現了這個。 對於某些人來說，它可能會有所幫助。

我錯誤地設置了水豚會話（它本身依賴於硒）

# WRONG
session = Capybara::Session.new(:selenium_chrome)

# CORRECT, see headless added
session = Capybara::Session.new(:selenium_chrome_headless)
