Issue using shebang to run SBCL Common LISP script as executable

Question

I've been trying to learn Common Lisp with SBCL and I've ran into issues executing my code. Everything works fine using sbcl --script exec.lisp (regardless of if I have specified a shebang line) but I can't seem to execute the same file with a shebang line directly as ./exec.lisp. While I've most likely misunderstood something the manual does from my understanding imply that this should be possible. My exec.lisp script looks identical to the one in the example (and it has been given executable privileges chmod a+x exec.lisp)

#!/usr/local/bin/sbcl --script
(write-line "Hello, World!")

but instead of the desired output I receive :

$ ./exec.lisp 
./exec.lisp: line 2: write-line: command not found

I've made sure that the path to sbcl is correct)

EDIT: I'm using mac OS.

Answer 1

Using GNU Core Utilities on Arch Linux here:

#!/usr/bin/env -S sbcl --script
(write-line "😻")

Answer 2

had same problem on MacOS, changed to:

#!/usr/bin/env sbcl --script

worked.

Answer 3

I would check the path supplied for sbcl (does it match the output of which sbcl ?)

I tried the following (running MacOS Mojave 10.14.4, SBCL version 1.4.16, obtained using nix instead of brew, but I doubt that makes a difference):

> $ which sbcl
/Users/abrahma/.nix-profile/bin/sbcl
