I'm using the exec-path-from-shell package to copy my environment variables, including PATH. But shell-command (M-! which ruby RET) only finds the system ruby, not my user-local rvm ruby.

Similarly, when I switch to a project using projectile and invoke projectile-compile-project (C-p c), the usual compilation command to build my website doesn't work, e.g.: "bundle exec nanoc compile"

It tries to use the system ruby:

-*- mode: compilation; default-directory: "~/Sites/christiantietze.de/" -*-
Compilation started at Sun Aug  2 12:23:46

bundle exec nanoc compile
Traceback (most recent call last):

The only way I found to use rvm from within emacs to do anything at all for me is to change the shell command to:

rvm default do bundle exec nanoc compile

So the rvm function is available and loaded in the shell; it's just that the PATH doesn't appear to be updated.

  • which ruby within shell returns /usr/bin/ruby
  • which ruby within eshell correctly returns /Users/ctm/.rvm/rubies/ruby-2.7.1/bin/ruby
  • (getenv "PATH") leads with "/Users/ctm/.rvm/rubies/ruby-2.7.1/bin", so the emacs environment should work
  • (getenv "SHELL") and shell-file-name report "/usr/local/bin/zsh" 👍 (explicit-shell-file-name is nil, but changing it to the same path didn't help, either)

Is there a way to make the regular emacs shell commands (and thus projectile) aware of the stuff that eshell knows?
