Since I recently upgraded to OpenBSD 7.5 I thought it could be helpful for others if I shared my process of building and using `rbenv` to install different Ruby versions. + +## Before We Build + +First, be sure to install the required packages in order to build from source, and then clone the core `rbenv` repo: + + pkg_add git gcc gmake libffi libyaml openssl + git clone https://github.com/rbenv/rbenv.git ~/.rbenv + +## Building `rbenv` + +Add `rbenv` to your PATH and initialize it (place this inside your `.bashrc` or `.zshrc` etc): + +```sh +export PATH="$HOME/.rbenv/bin:$PATH" +export PATH="$HOME/.rbenv/shims:$PATH" +export RUBY_CONFIGURE_OPTS="--with-openssl-dir=/usr/local" +eval "$(rbenv init -)" +``` + +Then reload your shell (zsh in this example): + +```sh +source ~/.zshrc +``` + +Next we will need to install `ruby-build` as a `rbenv` plugin. Clone the ruby-build repository into the rbenv plugins directory: + +```sh +git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build +``` + +## Installing Ruby and Setting Our Version + +Now use `rbenv` to install the desired version of Ruby (we will get an older version for this example): + +```sh +rbenv install 3.3.0 +``` + +If you run into issues, you may need to specify your openssl directory: + +```sh +RUBY_CONFIGURE_OPTS="--with-openssl-dir=/usr/local" rbenv install 3.3.0 +``` + +If you're on a slower machine (like mine) this might take a little bit. Just grab a coffee or a snack while you wait! + +Then navigate to your project of choice and set the `local` Ruby version: + +```sh +rbenv local 3.3.0 +``` + +That's it! If you'd prefer to set this version of Ruby for all projects going forward, simply replace `local` with `global`. |
