When sourcing .tmux.conf: "failed to connect to server: No such file or directory"

[raincoats]

I was following the install instructions, here's exactly what I did:

~ % mkdir ~/.tmux; cd ~/.tmux

~/.tmux % chmod 700 .

~/.tmux % git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm
# cloned fine

~/.tmux % nano ~/.tmux.conf
# I just added what it said to.
# If it's relevant, ~/.tmux.conf is a symlink to /my/dotfiles/.tmux.conf

everything was cool until this command:

~/.tmux % tmux source ~/.tmux.conf
failed to connect to server: No such file or directory

OS X 10.10.4 (newest), tmux 2.0 (via homebrew).

I'd test to see if the plugins work, but I actually didn't know tmux even had plugins, so I don't know how to do that/what these plugins do.

I'm an idiot, I realized that the tmux source must be done from tmux.

Works perfectly now.
