This is a short guide on the simplest way I have found how to install tmuxinator, which is used to create and manage tmux sessions.

bin(s): binary or binaries
dir(s): directory or directories

  1. Install ruby through a snap: sudo snap install ruby --classic
  2. Install tmuxinator: gem install tmuxinator
  3. Put the bin wherever you want to, it should be located in: ~/.gem/bin/tmuxinator

Normally, for the last step, since everything has been relative for my user I normally place the tmuxinator bin relative to my user as well. So, I normally do the following:

  1. create a local bin directory: mkdir -p ~/.local/bin
  2. Create a soft link between the ruby bin directory and my local bin directory like so: ln -s ~/.gem/bin/tmuxinator ~/.local/bin.

NOTE: make sure you have the local bin directory in your $PATH variable. i.e. adding this to your .zshrc or .bashrc:
export PATH=$PATH:~/.local/bin
If you don't, you won't be able to execute the tmuxinator binary.
