如何解决Python中WebDriver.__init__()意外参数'executable_path'错误

问题原因 #

你遇到的错误是因为Selenium 4.0及以上版本已移除executable_path参数，原有驱动初始化方式不再适用，需改用Service类管理浏览器驱动。同时原代码中生日字段的操作存在逻辑问题（列表无法直接调用send_keys），一并修复。

修复步骤 #

1. 导入ChromeService类用于驱动管理
2. 用ChromeService指定驱动路径，传入webdriver.Chrome()完成初始化
3. 调整生日下拉框的操作逻辑，逐个处理列表中的元素

    return (year, month, day)

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--disable-notifications")
chrome_options.add_argument("user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36")

# 改用Service类初始化驱动
service = ChromeService(executable_path='chromedriver')
driver = webdriver.Chrome(service=service, options=chrome_options)
wait = WebDriverWait(driver, 15)

driver.get('https://www.instagram.com/accounts/emailsignup/')

try:
    cookie_button = wait.until(EC.element_to_be_clickable((By.XPATH, "//button[text()='Allow essential and optional cookies']")))
    cookie_button.click()
except TimeoutException:
    print("Cookie acceptance button not found. Proceeding without it.")

email = generate_random_email()
email_field = wait.until(EC.presence_of_element_located((By.NAME, 'emailOrPhone')))
email_field.send_keys(email)

full_name = ' '.join(random.choices(string.ascii_letters, k=2)).title()
name_field = driver.find_element(By.NAME, 'fullName')
name_field.send_keys(full_name)

username = generate_random_username()
username_field = driver.find_element(By.NAME, 'username')
username_field.send_keys(username)

password = generate_random_password()
password_field = driver.find_element(By.NAME, 'password')
password_field.send_keys(password)

year, month, day = generate_birth_date()
birthday_fields = wait.until(EC.presence_of_all_elements_located((By.XPATH, "//select[@title='Year:'] | //select[@title='Month:'] | //select[@title='Day:']")))
# 按顺序处理年份、月份、日期下拉框
birthday_fields[0].send_keys(str(year))
birthday_fields[1].send_keys(str(month))
birthday_fields[2].send_keys(str(day))

time.sleep(2)

submit_button = driver.find_element(By.XPATH, "//button[text()='Sign Up']")
submit_button.click()

try:
    error_element = wait.until(EC.visibility_of_element_located((By.ID, 'ssfErrorAlert')))
    print("Error during signup:", error_element.text)
except TimeoutException:
    print("Form submitted. Check for verification steps (if any).")

input("Press Enter to close the browser...")
driver.quit()

额外优化建议 #

可以使用webdriver-manager库自动管理ChromeDriver，无需手动下载和指定路径：

1. 安装库：pip install webdriver-manager
2. 修改驱动初始化代码：

from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import ChromeService

service = ChromeService(ChromeDriverManager().install())
driver = webdriver.Chrome(service=service, options=chrome_options)
