When I tried to install flycheck package on emacs24, it show error that let-alist1.0.1 unavailable. But I heard that let-alist is built-in package of emacs25, I wonder is there any work-around for emacs24?

let-alist is available from ELPA. Use

M-x list-packages

to pull up a list of available packages, then search for let-atlist (C-M-s as usual). Then install it. See also here.

Alternatively, you can download it from here and install it manually. ELPA is easier, though.

  • Hi @Wintermute, I am using melpa, and it doesn't have let-alist package. Even when I add gnu elpa, it said cannot load from gnu elpa server. – OhMyGosh Feb 06 '15 at 03:02
  • Odd. I have `("gnu" . "http://elpa.gnu.org/packages/")` in my `package-archives`, and I have no trouble installing `let-alist` from there. But if it doesn't work for you, [here](http://ergoemacs.org/emacs/emacs_installing_packages.html)'s a way to install packages manually. – Wintermute Feb 06 '15 at 09:10
  • Lol, that's really odd! Something's wrong with my internet or gnu server. It keeps contacting host: elpa.gnu.org:80, never show up the list of packages. – OhMyGosh Feb 06 '15 at 09:53
