Ruby on Rails项目创建异常：仅生成文件无文件夹且报错

执行rails new blog创建Ruby on Rails项目时，仅生成README.md、Rakefile等根文件，未创建完整项目文件夹，同时出现以下错误：

E:\Gamess\Ruby>rails new blog
  create
  create  README.md
  create  Rakefile
  create  .ruby-version
  create  config.ru
  create  .gitignore
  create  .gitattributes

解决方法 #

临时方案：跳过Git初始化 #

创建项目时添加--skip-git参数，绕过Git相关步骤：

rails new blog --skip-git

永久方案：修复Git环境 #

1. 安装Git：如果未安装Git，下载安装包并完成安装，注意勾选「Add Git to your PATH」选项（默认通常已勾选）
2. 验证Git可用性：打开命令行执行git --version，能正常输出Git版本号即为配置成功
3. 重新创建项目：执行rails new blog即可正常生成完整项目文件夹
