Ruby安装方法咨询及Windows 7 32位新手适用代码编辑器推荐请求

Hey Alex, since you're a Ruby beginner on Windows 7 32-bit with GNU Compiler set up, let's break down your questions clearly:

The most reliable way for your setup is using RubyInstaller—it’s tailored for Windows and includes the DevKit package that works seamlessly with your GNU Compiler, which is essential for installing gems that require compilation. Here’s step-by-step guidance:

• First, pick a Ruby version that supports Windows 7 32-bit. Newer Ruby versions (like 3.x+) dropped Win7 support, so go for Ruby 2.6.x series (the latest stable release in this range is 2.6.10).
• Download the 32-bit RubyInstaller package from its official, trusted source (avoid third-party sites to stay virus-free).
• Run the installer, and make sure to check the box that says Add Ruby executables to your PATH—this lets you run Ruby commands directly from the command prompt.
• Next, download the matching 32-bit DevKit package, extract it to a permanent folder (e.g., C:\DevKit).
• Open Command Prompt, navigate to the DevKit folder, and run these commands to link DevKit with your Ruby installation:

  ruby dk.rb init
  ruby dk.rb install
  

• To confirm everything works, type ruby -v and gem -v in the command prompt—you should see the version numbers of Ruby and RubyGems displayed.

Here are three virus-free, beginner-friendly editors you can trust, all available from official, secure sources:

• Notepad++: A completely free, lightweight editor with built-in Ruby syntax highlighting. It’s easy to use for quick code edits, and you can add plugins later if you want more features. Just grab it from its official homepage to avoid bundled junk.
• Sublime Text: A sleek, fast editor with great syntax highlighting and basic code completion. It’s a paid tool but offers unlimited free trials, making it perfect for beginners who want a polished experience without immediate cost. Stick to the official download page for safety.
• Visual Studio Code: Microsoft’s free, open-source editor. Once you install the Ruby LSP (Language Server Protocol) plugin, you get advanced features like code suggestions, formatting, and error checking—ideal if you plan to stick with Ruby long-term. Download directly from Microsoft’s official site to ensure it’s virus-free.
