People hit this using GUI Emacs on macOS -- and use the `exec-path-from-shell` Emacs Lisp package:
https://github.com/purcell/exec-path-from-shell <blockquote> Ever find that a command works in your shell, but not in Emacs? This happens a lot on OS X, where an Emacs instance started from the GUI inherits a default set of environment variables. This library solves this problem by copying important environment variables from the user's shell: it works by asking your shell to print out the variables of interest, then copying them into the Emacs environment. </blockquote> The source is <270 lines of Emacs Lisp -- of which >200 is comments and boilerplate. Maybe someone could make an equivalent DrRacket plugin and provide it as a Racket package? -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
