install Ruby using RTX (asdf Rust clone)

ruby_rtx.md

Here's a guide for installing Ruby on Windows Subsystem for Linux (WSL) using rtx, a polyglot runtime manager:

1. Install RTX: First, install rtx. You can do this by downloading the binary for Linux from the RTX releases page on GitHub. Choose the appropriate version for your system (e.g., rtx-latest-linux-x64 for 64-bit Linux).

   bashCopy code

   curl -L https://github.com/jdx/rtx/releases/download/latest/rtx-latest-linux-x64 > ~/bin/rtx chmod +x ~/bin/rtx

2. Add RTX to PATH: Make sure that rtx is in your PATH. You can do this by adding the following line to your .bashrc or .zshrc:

   bashCopy code

   export PATH="$HOME/bin:$PATH"

3. Activate RTX: To initialize rtx in your shell session, you need to add an activation command to your shell's configuration file. For Bash, add the following line to your .bashrc:

   bashCopy code

   eval "$(~/bin/rtx activate bash)"

   For Zsh, add it to your .zshrc.

4. Install Ruby Using RTX: Now, you can use rtx to install Ruby. Specify the version you want to install. For example, to install Ruby version 2.7.2:

   cssCopy code

   rtx install ruby@2.7.2

5. Set Ruby Version: After installing, set the Ruby version for your project or globally. To set it for the current directory:

   perlCopy code

   rtx use ruby@2.7.2

   To set it globally (for all directories), use:

   cssCopy code

   rtx use --global ruby@2.7.2

6. Verify Installation: Finally, verify the installation by checking the Ruby version:

   undefinedCopy code

   ruby -v

This should install Ruby on your WSL environment using rtx. Remember to replace 2.7.2 with the version of Ruby you need.
