How to install plugins automatically?

[LittleNewton]

I am trying to build a Tmux auto-configuring project and I wish when tmux.conf exists, all the declared plugins will be installed once a new Tmux session is created without pressing <prefix>I.

It is helpful because many people have no sense of installing plugins by hand.

I have read docs of Automatic tpm installation. It is very helpful.

What if it doesn't work when you Add auto plugin installation? Try replacing bin/install_plugins with bindings/install_plugins. It is helpful to me.
