当我运行我的脚本时,我收到了此错误
Traceback (most recent call last):

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()

如果我们分析日志,主要问题似乎是 start os.path.basename(self.path)
以及后续错误消息 selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH
。
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。
你必须在这里处理几点:
chrome_options.binary_location
:该参数配置 chrome.exe
而非 chromedriver.exe
os.path.abspath("chromedriver")
会选择 chromedriver
的文件路径,但最后不会附加 chromedriver.exe
。 以下是我的Windows 8
系统中的示例代码,用于在 Chrome
中启动 Headless Mode
:
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")

我在Linux中有相同的错误。解决方法非常简单。只需运行此命令,错误就会消失。
sudo apt install chromium-chromedriver
