无法使用Selenium for Python打开Chrome WebDriver
无法使用Selenium for Python打开Chrome WebDriver
提问于 2018-03-16 21:49:15
我正在尝试以下脚本，但无法使其打开Webdriver：
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Chrome('/usr/bin/google-chrome')
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()这会产生以下错误消息：
Traceback (most recent call last):
File "scraper.py", line 4, in <module>
driver = webdriver.Chrome('/usr/bin/google-chrome')
File "/home/joseph/.local/lib/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 68, in __init__
self.service.start()
File "/home/joseph/.local/lib/python2.7/site-packages/selenium/webdriver/common/service.py", line 98, in start
self.assert_process_still_running()
File "/home/joseph/.local/lib/python2.7/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: 1我使用的是运行在Windows10上的Ubuntu 16.04，你知道这是什么吗？
编辑：
现在我使用chromedriver执行此操作，我将其解压缩到与脚本相同的目录中。
driver = webdriver.Chrome(executable_path='./chromedriver')我得到以下错误，而不是前一个错误：
Traceback (most recent call last):
File "scraper.py", line 4, in <module>
driver = webdriver.Chrome(executable_path='./chromedriver')
File "/home/joseph/.local/lib/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 75, in __init__
desired_capabilities=desired_capabilities)
File "/home/joseph/.local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 154, in __init__
self.start_session(desired_capabilities, browser_profile)
File "/home/joseph/.local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 243, in start_session
response = self.execute(Command.NEW_SESSION, parameters)
File "/home/joseph/.local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 312, in execute
self.error_handler.check_response(response)
File "/home/joseph/.local/lib/python2.7/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response

在使用Selenium v3.11.0、ChromeDriver v2.36和Chromev64.x时，您必须从ChromeDriver - WebDriver for Chrome下载最新的ChromeDriver并将其放入系统中。接下来，在初始化WebDriver和WebBrowser时，必须提到ChromeDriver的绝对路径，如下所示：
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Chrome(executable_path='/path/to/chromedriver')
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.quit()注意：在测试执行的末尾，而不是
close()，调用quit()方法，这样WebDriver和WebBrowser都会被销毁。

您可能需要尝试不同版本的驱动程序，这取决于chrome的版本。此外，请确保路径正确并指向可执行驱动程序文件(.exe) driver = webdriver.Chrome(executable_path='./chromedriver/chromedriver.exe')
