WebDriverException:消息:服务/usr/bin/google-chrome 意外退出.状态代码是:-11 with ChromeDriver Chrome through Selenium Python [英] WebDriverException: Message: Service /usr/bin/google-chrome unexpectedly exited. Status code was: -11 with ChromeDriver Chrome through Selenium Python

问题描述

我正在尝试在 Python 脚本中运行 webdriver，当脚本尝试运行 google chrome 时，它​​会以状态码 11 退出.

I am trying to run webdriver in a Python script, and when the script tries to run google chrome it exits with status code 11.

这里是python脚本:

Here is the python script:

#!/usr/bin/python3
import time
from selenium import webdriver

driver = webdriver.Chrome('/usr/bin/google-chrome')  # Optional argument, if not specified will search path.
driver.get('http://www.google.com/');
time.sleep(5) # Let the user actually see something!
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!
driver.quit()

这是完整的输出:

[ec2-user@ip-xxx-xx-xx-xxx pythonscrape]$ python3 test-selenium-chrome.py
Traceback (most recent call last):
  File "test-selenium-chrome.py", line 5, in <module>
    driver = webdriver.Chrome('/usr/bin/google-chrome')  # Optional argument, if not specified will search path.
  File "/usr/local/lib/python3.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 73, in __init__
    self.service.start()
  File "/usr/local/lib/python3.7/site-packages/selenium/webdriver/common/service.py", line 98, in start
    self.assert_process_still_running()
  File "/usr/local/lib/python3.7/site-packages/selenium/webdriver/common/service.py", line 111, in assert_process_still_running
    % (self.path, return_code)
selenium.common.exceptions.WebDriverException: Message: Service /usr/bin/google-chrome unexpectedly exited. Status code was: -11

有谁知道为什么我的脚本在尝试运行 google chrome 时会报告错误代码 11?

Does anyone know why my script reports the error code 11 when trying to run google chrome?

推荐答案

这个错误信息...

selenium.common.exceptions.WebDriverException: Message: Service /usr/bin/google-chrome unexpectedly exited. Status code was: -11

...暗示 ChromeDriver 无法正确启动/生成新的 Browsing Context 即 Chrome 浏览器 会话.

...implies that the ChromeDriver was unable to initiate/spawn the new Browsing Context i.e. Chrome Browser session properly.

看来你快到了.webdriver.Chrome() 的默认参数是 ChromeDriver 二进制文件的绝对路径.但是，根据最佳实践，您必须同时发送 Key 和 Value，如下所示:

Seems you were almost there. The default argument for webdriver.Chrome() is the absolute path of the ChromeDriver binary. However, as per best practices you must send both the Key and the Value as follows:

driver = webdriver.Chrome(executable_path='/path/to/chromedriver')  # Optional argument, if not specified will search path

此外，如果您需要传递 Chrome 二进制文件的绝对路径，您必须通过 chrome.options如下:

Further, if you need to pass the absolute path of the Chrome binary you have to use the binary_location property through an instance of chrome.options as follows:

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

options = Options()
options.binary_location = '/path/to/chrome'
driver = webdriver.Chrome(options=options, executable_path='/path/to/chromedriver')
driver.get('http://google.com/')
