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以上是关于selenium.common.exceptions.WebDriverException:消息:“chromedriver”可执行文件需要在无头 Chrome 的 PATH 错误中的主要内容,如果未能解决你的问题,请参考以下文章
