Microsoft Edge Driver启动失败求助（Google Colab环境）

在Google Colab运行Selenium Edge自动化代码时，启动Edge Driver失败，抛出WebDriverException，核心错误提示：

unknown error: Microsoft Edge failed to start: exited abnormally.
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from msedge location /usr/bin/microsoft-edge is no longer running, so msedgedriver is assuming that msedge has crashed.)

已完成的排查步骤：

• EdgeDriver与Microsoft Edge版本完全匹配
• WebDriver路径配置正确
• Selenium已更新至最新版本
• 执行chmod +x msedgedriver赋予执行权限

解决方案 #

问题核心是Google Colab的Linux无头环境缺少必要的浏览器启动参数，需修改edge_options配置，添加以下关键参数：

1. 启用无头模式：Colab无图形界面，必须以无头模式启动浏览器
2. 禁用沙箱：避免Linux环境下的权限限制导致启动失败
3. 指定DevTools端口与临时路径：解决DevToolsActivePort文件不存在的问题
4. 禁用GPU与设置窗口大小：适配Colab环境的资源限制

修改后的完整代码

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.edge.service import Service
import tempfile

# Prompt the user for credentials
username = input("Enter your username: ")
password = input("Enter your password: ")

# WebDriver路径（注意Colab中Linux环境无需.exe后缀）
webdriver_path = "/usr/local/bin/microsoft-edgedriver"

edge_options = webdriver.EdgeOptions()

# 核心配置：适配Colab无头环境
edge_options.add_argument("--headless=new")  # 新版无头模式，兼容性更好
edge_options.add_argument("--no-sandbox")    # 禁用沙箱，解决权限问题
edge_options.add_argument("--disable-dev-shm-usage")  # 避免共享内存不足
edge_options.add_argument("--remote-debugging-port=9222")  # 指定DevTools端口
edge_options.add_argument("--window-size=1920,1080")  # 设置窗口大小
edge_options.add_argument("--disable-gpu")  # 禁用GPU，适配无头环境

# 创建临时目录存放DevTools相关文件
temp_dir = tempfile.mkdtemp()
edge_options.add_argument(f"--user-data-dir={temp_dir}")
edge_options.add_argument(f"--data-path={temp_dir}")
edge_options.add_argument(f"--disk-cache-dir={temp_dir}")

# 初始化Driver（建议使用Service类，Selenium 4+推荐写法）
service = Service(webdriver_path)
driver = webdriver.Edge(service=service, options=edge_options)

try:
    # 执行自动化流程
    driver.get("https://login.live.com/")
    
    # 等待并输入用户名
    username_field = WebDriverWait(driver, 10).until(
        EC.visibility_of_element_located((By.NAME, "loginfmt"))
    )
    username_field.send_keys(username)
    username_field.send_keys(Keys.RETURN)
    
    # 等待并输入密码
    password_field = WebDriverWait(driver, 10).until(
        EC.visibility_of_element_located((By.NAME, "passwd"))
    )
    password_field.send_keys(password)
    password_field.send_keys(Keys.RETURN)
    
    # 等待搜索框并执行搜索
    search_box = WebDriverWait(driver, 15).until(
        EC.visibility_of_element_located((By.NAME, "q"))
    )
    search_box.send_keys("hello")
    search_box.send_keys(Keys.RETURN)
    
finally:
    # 确保浏览器关闭
    driver.quit()

额外注意事项

• 移除WebDriver路径中的.exe后缀：Colab是Linux环境，可执行文件无需Windows后缀
• 使用Service类初始化Driver：Selenium 4及以上版本推荐使用Service替代直接指定executable_path
• 添加try-finally块：保证无论是否出错都能关闭浏览器，避免资源泄漏
