Windows下创建Ruby on Rails应用时遇Errno::ENOENT错误求助

问题详情 #

我是Ruby on Rails新手，使用Windows版RubyInstaller（3.3.0版本）安装了Ruby和Rails（7.1.3.2版本），并在CMD中确认版本无误。但执行rails new schedule_tweet命令创建新应用时，持续出现Errno::ENOENT错误，提示No such file or directory - git config init.defaultbranch。我已确认Ruby安装目录下的app_base.rb文件存在，尝试手动添加Ruby至环境变量Path、重装Ruby及更换Ruby版本，均未解决问题。

解决方案 #

• 方案1：跳过Git初始化
  执行rails new命令时添加--skip-git参数，直接跳过Git仓库初始化步骤：

  rails new schedule_tweet --skip-git
  

• 方案2：安装Git并配置环境变量

  1. 下载Windows版Git并完成安装；
  2. 安装时确保勾选“Add Git to PATH”选项；
  3. 重启CMD，执行git --version确认Git可用；
  4. 再次尝试rails new schedule_tweet命令。

• 方案3：手动配置Git默认分支（可选）
  若安装Git后仍有问题，先手动设置Git默认分支：

  git config --global init.defaultbranch main
  

  之后再执行rails new命令。
