使用WebdriverIO v8安装Appium失败：无法添加package.json脚本

尝试安装Appium并搭配WebdriverIO v8使用，配置WebdriverIO 8时选择了以下选项：

    ? Do you want WebdriverIO to autogenerate some test files? No
    ? Which reporter do you want to use? spec

安装时出现如下错误：

⚠️  Ups, something went wrong: Error calling: npx wdio config!

• 检查项目根目录的package.json是否存在语法错误，比如缺失逗号、引号不闭合，这是npm无法写入脚本的常见诱因。
• 若package.json无语法问题，手动添加wdio脚本：打开package.json，在scripts字段中加入"wdio": "wdio run ./wdio.conf.js"。
• 手动执行npm install完成依赖安装。
• 尝试升级npm版本：执行npm install -g npm后，重新运行配置向导。
• 跳过自动配置流程，手动创建wdio.conf.js并填写Appium相关配置，再手动安装所需依赖（如@wdio/cli、@wdio/mocha-framework、@wdio/spec-reporter、@wdio/appium-service等）。
