I am a total emacs newbie and am trying to figure my way around emacs(I am kinda liking it). Now my question is that when I type rails commands in my terminal, they work perfectly well.

user ~ $ rails -v
Rails 4.2.1

But when I run the same commands in eshell, I get:

Welcome to the Emacs shell

~/.emacs.d $ rails -v
rails: command not found

To my understanding, eshell is a shell within emacs. Right? Or I have it completely wrong?

  • Emacs uses PATH as defined by the environment it was started from. If you've changed PATH only in your shell, it will obviously not work. – wasamasa May 16 '15 at 12:45
  • @wasamasa How do I make it work? – xandfury May 16 '15 at 12:51

Eshell does not run your default shell, so it will ignore whatever you have set up in the shell rc script.

You can set environment variables in ~/.eshell/login or ~/.eshell/profile, use addpath PATH (for some string value of PATH), or add a hook to evaluate (setenv ...) with the appropriate values.

For a more regular shell I recommend using M-x shell, which just communicates with an external shell process.
