I am using emacs with org mode to take notes. I read that org mode can export to pdf whene you type C-c C-e lp. When I type this in, *Org PDF LaTeX Output* buffer says :

/bin/bash: pdflatex: command not found

But when I run $ pdflatex on my terminal the program executes. I belive that emacs doesn't login in bash, and as a result it doesn't have acces to my $PATH variable.

Do you have any idea how I can fix this. Thanks in advance.

  • Where is pdflatex on your system? What is your $PATH outside of emacs (echo $PATH in a shell) and inside Emacs ((getenv "PATH"))?

I have the same problem when the Emacs PATH does not copy the contents of the login shell. I run this in the Emacs *scratch* buffer:

(getenv "PATH")

(Alternatively, hit M-x and type getenv, then type PATH.)

I searched for the location of pdflatex in a login shell in Terminal with:

> which pdflatex

So I added that directory to the PATH, e.g. add this to .emacs:

(setenv "PATH" (concat (getenv "PATH") ":/Library/TeX/texbin"))

and source it again with M-x load-file and type ~/.emacs. And now C-c C-e lp in Org-mode works:

PDF file produced.
