WebDriverException：消息：未知错误：C:/.../Chrome/Application/chrome.exe 中没有带有 ChromeDriver Selenium 和 Python 的 chrome 二进制文件

Question

这里有点 Python 新手...

Windows 7 x64 和 Python 3.7

我已经安装了 Selenium 和 Chrome Webdriver。我正在使用：

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

options = Options()
options.binary_location = 'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe'
driver = webdriver.Chrome(chrome_options=options, executable_path='C:/python/chromedriver.exe')
driver.get('http://google.com/')

我明白了：

\python\python.exe C:/py/defectURLS/app.py
C:/py/defectURLS/app.py:6: DeprecationWarning: use options instead of chrome_options
  driver = webdriver.Chrome(chrome_options=options, executable_path='C:/python/chromedriver.exe')
Traceback (most recent call last):
  File "C:/py/defectURLS/app.py", line 6, in <module>
    driver = webdriver.Chrome(chrome_options=options, executable_path='C:/python/chromedriver.exe')
  File "C:\python\lib\site-packages\selenium-3.141.0-py3.7.egg\selenium\webdriver\chrome\webdriver.py", line 81, in __init__
    desired_capabilities=desired_capabilities)
  File "C:\python\lib\site-packages\selenium-3.141.0-py3.7.egg\selenium\webdriver\remote\webdriver.py", line 157, in __init__
    self.start_session(capabilities, browser_profile)
  File "C:\python\lib\site-packages\selenium-3.141.0-py3.7.egg\selenium\webdriver\remote\webdriver.py", line 252, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "C:\python\lib\site-packages\selenium-3.141.0-py3.7.egg\selenium\webdriver\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "C:\python\lib\site-packages\selenium-3.141.0-py3.7.egg\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: no chrome binary at C:/Program Files (x86)/Google/Chrome/Application/chrome.exe
  (Driver info: chromedriver=2.43.600210 (68dcf5eebde37173d4027fa8635e332711d2874a),platform=Windows NT 6.1.7601 SP1 x86_64)

现在，我很确定确凿证据是：

 selenium.common.exceptions.WebDriverException: Message: unknown error: no chrome binary at C:/Program Files (x86)/Google/Chrome/Application/chrome.exe
      (Driver info: chromedriver=2.43.600210 (68dcf5eebde37173d4027fa8635e332711d2874a),platform=Windows NT 6.1.7601 SP1 x86_64)

这表明 Selenium 可以找到 webdriver 正常，因为它能够报告 webdriver 版本。该错误似乎表明 chrome 二进制文件未位于给定位置。但我完全确定这是 Chrome.exe 所在的位置。我可以直接从该路径启动 chrome.exe，完全没有问题。

非常感谢指导可能出现的问题。

此错误消息...

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally

...暗示 ChromeDriver 无法找到 chrome 二进制文件 chrome.exe

您需要考虑以下几个事实：

• 您可能正在使用 Selenium Python Client v3.14.1 或 Selenium Python Client v3.141.0，而 chrome_options 现在已弃用。您需要使用 options 虽然 chrome_options 仍然有效。
• Key executable_path 必须支持以下任一Value：
  • r'C:\python\chromedriver.exe'
  • "C:/python/chromedriver.exe"
  • "C:\\python\\chromedriver.exe"
