我已经在 Mac 上设置了我需要的一切(Ruby、Rails、Homebrew、Git 等)，我什至编写了一个小程序.现在，我如何在终端中执行它?我在 Redcar 中编写了程序并将其保存为 .rb，但我不知道如何通过终端执行它.我想运行该程序，看看它是否真的有效.我该怎么做呢?

I've set everything up that I need on my Mac (Ruby, Rails, Homebrew, Git, etc), and I've even written a small program. Now, how do I execute it in Terminal? I wrote the program in Redcar and saved it as a .rb, but I don't know how to execute it through Terminal. I want to run the program and see if it actually works. How do I do this?

推荐答案

只需调用:ruby your_program.rb

或

• 用 #!/usr/bin/env ruby​​ 启动你的程序，
• 通过运行 chmod +x your_program.rb
使您的文件可执行
• 然后做./your_program.rb some_param

• start your program with #!/usr/bin/env ruby,
• make your file executable by running chmod +x your_program.rb
• and do ./your_program.rb some_param
