Python Selenium ChromeDriver加载失败：WinError 193问题求助

DevOps 小满

问题描述

代码中使用的依赖库：

from arcgis.gis import GIS
from arcgis.geometry import Point, Polyline, Polygon
import datetime
import os
from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
from selenium.webdriver.common.keys import Keys
from webdriver_manager.chrome import ChromeDriverManager 
import time
from selenium.webdriver.support.select import Select
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from getpass import getpass

已执行pip install -r requirements.txt安装依赖，但运行代码时出现ChromeDriver加载错误，报错信息：

PS E:\code\esri\FissionStaking2> python .\marswaitforlogin.py

请问缺少什么配置或操作导致该错误？

解决方案

Chrome与ChromeDriver版本/架构不匹配：WinError193最常见原因是驱动和浏览器版本不对，或者32/64位架构不兼容。先查看Chrome版本（Chrome菜单→帮助→关于Google Chrome），要么手动下载对应版本的ChromeDriver替换自动下载的文件，要么在代码里指定版本安装：
```
driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager(version="你的Chrome对应版本号").install()))
```
自动下载的驱动损坏：WebDriverManager缓存的驱动可能因网络问题损坏，导致无法识别为有效Win32程序。删掉缓存文件夹（默认路径C:\Users\<你的用户名>\.wdm\drivers\chromedriver）后重新运行代码，或者手动下载驱动后直接指定路径：
```
driver = webdriver.Chrome(service=ChromeService(executable_path="你的ChromeDriver.exe完整路径"))
```
Python与驱动架构不匹配：如果你的Python是32位版本，却下载了64位ChromeDriver（反之亦然），会触发该错误。运行python --version查看是否有32-bit标识，下载对应架构的驱动即可。
Chrome安装异常：若Chrome浏览器本身安装损坏，或安装路径包含中文、特殊字符，也会导致驱动无法正常调用。尝试重装Chrome，确保安装路径无特殊字符。
