WebdriverIO下载Chromedriver失败，如何配置实现稳定运行？

问题场景 #

初始化WebdriverIO脚本时，遇到Chromedriver v122.0.6261.57下载失败（服务器返回500状态码），尝试在package.json指定版本无效，工具仍自动尝试下载最新版。

解决方法 #

• 在wdio.conf.js中强制指定版本
  WebdriverIO的chromedriver服务配置优先级高于package.json，直接修改配置文件中的services项即可锁定版本：

  exports.config = {
    // 其他配置...
    services: [
      ['chromedriver', {
        version: '121.0.6167.85', // 替换为你确认可用的稳定版本号
        // 可选：官方源下载慢的话，添加国内镜像源
        // mirror: 'https://npm.taobao.org/mirrors/chromedriver/'
      }]
    ]
  }
  

• 手动下载并指定本地路径
  如果自动下载始终失败，直接手动下载对应系统的Chromedriver压缩包，解压后在配置里指定本地路径：

  exports.config = {
    // 其他配置...
    services: [
      ['chromedriver', {
        path: './chromedriver.exe', // Windows系统带.exe后缀，Mac/Linux去掉
        version: false // 关闭自动下载功能
      }]
    ]
  }
  

• 修正package.json依赖版本
  确认package.json中chromedriver和wdio-chromedriver-service版本适配，示例配置：

  "dependencies": {
    "chromedriver": "^121.0.0",
    "wdio-chromedriver-service": "^8.1.1"
  }
  

  执行npm install重新安装依赖。

• 临时跳过驱动下载
  运行测试时添加参数，跳过自动下载步骤，直接使用已有的本地驱动：

  npx wdio run wdio.conf.js --skip-driver-install
