M-x slime [No match]

I installed Emacs 29.2 and sbcl 2.4.0.

Then I installed slime using the command M-x package-install<Ret>slime<Ret>. I can see that slime is installed (M-x list-packages):

Now, I'm trying to get slime to work following these instructions:

It is simple as:

1. Open emacs
2. Open your lisp file with fibonacci function
3. Issue M-x slime
4. Place you cursor over fibonacci function and press C-c C-c to evaluate/compile it in Slime.
5. switch to slime window and call (fibonacci 10)

Screenshot example with hello-world function:

In emacs, I opened a hello world .lisp file with C-x C-f. However, when I type M-x slime<Ret>, I get [No match]. Same for M-x slime-mode<Ret>.

Here is my ~/.emacs file:

(custom-set-variables
 ;; custom-set-variables was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 '(package-selected-packages '(slime paredit)))
(custom-set-faces
 ;; custom-set-faces was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 )

;;;;;;;;;;;;;;;;;;;;;;;

;; I added the following according to slime install directions:

(setq inferior-lisp-program "sbcl")

sbcl is in my path:

% which sbcl
/opt/local/bin/sbcl

% echo $PATH
...:/Users/7stud/bin/:/opt/local/bin:....

I tried altering the .emacs file to use the full path to sbcl:

(setq inferior-lisp-program "/opt/local/bin/sbcl")

but I still get M-x slime [No match]. I've been quitting emacs and relaunching it after I make changes to the .emacs file.

Here is my ~/.emacs.d/elpa directory (which I haven't touched):

% ls
archives               macrostep-0.9.2.signed slime-2.29.1
gnupg                  paredit-26             slime-2.29.1.signed
macrostep-0.9.2        paredit-26.signed

There were a bunch of warnings when I installed slime, but I can't find where those warnings are logged, so I can't post them.

I was able to successfully install and use the package paredit. When I open a .lisp file, it opens in Lisp major-mode, and if I do M-x paredit-mode, that adds Paredit as a minor-mode:

After adding Paredit as a minor-mode, parentheses get matched, so it works.

I'm on macOS 12.5.1, and I installed emacs with:

% sudo port install emacs-app 

Edit: =======

I unistalled slime by displaying the package list, M-x list-packages, then searching for the slime listing, C-s, then typing d on the slime listing, then typing x. I reinstalled slime by finding the slime listing again, then typing i on the slime line, then x. Here are the warnings:

You were nearly there:

However, when I type M-x slime, I get [No match]

you are missing

(require 'slime)

You must add this in your ~/.emacs (or "~/.emacs.d/init.el") and you can evaluate in your current session with M-: or M-x eval-expression<Ret> (require 'slime)<Ret>.
