[英]selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH
[英]selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH error with Headless Chrome
當我運行我的腳本時,我得到了這個錯誤

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home
這是我的腳本
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()
如果我們分析日志,似乎主要問題在於start os.path.basename(self.path)
和后續錯誤消息selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH
。
因此,從錯誤中可以清楚地看出 Python 客戶端無法定位chromedriver
二進制文件。
您必須在這里注意以下幾點:
chrome_options.binary_location
:該參數配置的是chrome.exe
而不是chromedriver.exe
os.path.abspath("chromedriver")
將拿起的文件路徑chromedriver
但不會追加chromedriver.exe
底。 這是在我的Windows 8
系統上以Headless Mode
啟動Chrome
的示例代碼:
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")
