Initialization error trying to install elpy for emacs

Question

Evening,

I'm trying to install a package for emacs having never done so before. I am using the following guide https://realpython.com/emacs-the-best-python-editor/ which intends to install elpy.

The following information is placed in ~/.emacs.d/init.el

;; .emacs.d/init.el 2 3;; =================================== 4;; MELPA Package Support 5;; =================================== 6;; Enables basic packaging support 7(require 'package) 8 9;; Adds the Melpa archive to the list of available repositories 10(add-to-list 'package-archives 11 '("melpa" . "http://melpa.org/packages/") t) 12 13;; Initializes the package infrastructure 14(package-initialize) 15 16;; If there are no archived package contents, refresh them 17(when (not package-archive-contents) 18 (package-refresh-contents)) ;; Installs packages 21;; 22;; myPackages contains a list of package names 23(defvar myPackages 24 '(better-defaults elpy ;; Set up some better Emacs defaults 25 material-theme ;; Theme 26 ) 27 ) 28 29;; Scans the list in myPackages 30;; If the package listed is not already installed, install it 31(mapc #'(lambda (package) 32 (unless (package-installed-p package) 33 (package-install package))) 34 myPackages) ;; =================================== 37;; Basic Customization 38;; =================================== 39 40(setq inhibit-startup-message t) ;; Hide the startup message 41(load-theme 'material t) ;; Load material theme 42(global-linum-mode t) ;; Enable line numbers globally 43;; ==================================== 46;; Development Setup 47;; ==================================== 48;; Enable elpy 49(elpy-enable) 50 51;; User-Defined init.el ends here

However, this I pumped out in emacs when I load after saving.

Warning (initialization): An error occurred while loading ‘/Users/jay/.emacs.d/init.el’:

Symbol's function definition is void: t

Has anyone run into this issue before? Thanks

Somewhere in some code you're evaluating (e.g. code you're loading), you are trying to invoke t as a function.

It's likely that you meant to quote a list whose car is t: '(t ...), and you forgot the quote mark: (t ...).

Lisp tries to interpret and unquoted list as a function call, with the function being the car of the list.

I don't see such an unquoted list in the code you show. Perhaps its in some code that that code loads. To find the problem, bisect your init file. You can use command comment-region to comment (and with C-u uncomment) a region of code.
