【中文标题】selenium.common.exceptions.WebDriverException:消息:“chromedriver”可执行文件需要在无头 Chrome 的 PATH 错误中【英文标题】:selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH error with Headless Chrome 【发布时间】:2018-02-15 12:54:45 【问题描述】:

当我运行我的脚本时,我得到了这个错误

Traceback (most recent call last):
  File "C:\Users\ishaq\AppData\Local\Programs\Python\Python36\lib\site-packages\selenium\webdriver\common\service.py", line 74, in start

FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:/Users/ishaq/AppData/Local/Programs/Python/Python36/headless.py", line 9, in <module>
    driver = webdriver.Chrome(executable_path=os.path.abspath("chromedriver"),   chrome_options=chrome_options)
  File "C:\Users\ishaq\AppData\Local\Programs\Python\Python36\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 62, in __init__

    os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

这是我的脚本

import os  
from selenium import webdriver  
from selenium.webdriver.common.keys import Keys  
from selenium.webdriver.chrome.options import Options 

chrome_options = Options()  
chrome_options.add_argument("--headless")  
chrome_options.binary_location = 
r'C:\Users\ishaq\Desktop\chrome\chromedriver.exe'    
driver = webdriver.Chrome(executable_path=os.path.abspath("chromedriver"),   
chrome_options=chrome_options)  
driver.get("http://www.duo.com") 

magnifying_glass = driver.find_element_by_id("js-open-icon")  
if magnifying_glass.is_displayed():  
  magnifying_glass.click()  
else:  
  menu_button = driver.find_element_by_css_selector(".menu-trigger.local")  
  menu_button.click() 

search_field = driver.find_element_by_id("site-search")  
search_field.clear()  
search_field.send_keys("Olabode")  
search_field.send_keys(Keys.RETURN)  
assert "Looking Back at android Security in 2016" in driver.page_source
driver.close()

【问题讨论】:

Error message: "'chromedriver' executable needs to be available in the path"的可能重复 在发布问题之前,您应该花一些时间阅读错误消息并尝试了解错误是什么。然后你应该花一些时间在谷歌上搜索错误,以便更好地理解错误的含义以及人们如何解决它们。这是一个常见错误,如果您花时间寻找它,已经有解决方案。 @JeffC 实际上我对 os.path 和 binary.location 感到困惑。我搜索了很多关于它并没有找到解决方案,这就是我发布这个问题的原因。 【参考方案1】:

如果我们分析日志,似乎主要问题在于 start os.path.basename(self.path) 和随后的错误消息 selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH

因此,从错误中可以清楚地看出 Python 客户端无法找到 chromedriver 二进制文件。

您必须注意以下几点:

    chrome_options.binary_location :该参数配置 chrome.exe 而不是 chromedriver.exe os.path.abspath("chromedriver") 会选择 chromedriver 的文件路径,但不会在末尾附加 chromedriver.exe

    这是我的Windows 8系统上的示例代码,用于在Headless Mode中启动Chrome

    from selenium import webdriver  
    from selenium.webdriver.chrome.options import Options 
    
    chrome_options = Options()  
    chrome_options.add_argument("--headless")  
    driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')  
    driver.get("http://www.duo.com") 
    print("Chrome Browser Initialized in Headless Mode")
    driver.quit()
    print("Driver Exited")
    

【讨论】:

或者你也可以试试Mozilla Firefox in Headless Mode 我的脚本在本地运行良好,但我想远程运行我的脚本,我不想整天运行我的机器
