您是如何“导入”github MELPA获取器的？

Question

当我的Symbol's value as variable is void: github文件中有以下内容时，我得到.emacs (错误来自最后一个表达式)：

(require 'package)
(add-to-list 'package-archives
             '("MELPA Stable" . "http://stable.melpa.org/packages/") t)
(add-to-list 'package-archives
             '("gnu" . "http://elpa.gnu.org/packages/") t )

(package-initialize)
(package-refresh-contents)

(package-install 'flycheck)

(global-flycheck-mode)
(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 (quote (haskell-mode idris-mode flycheck))))
(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.
 )

(add-hook 'after-init-hook #'global-flycheck-mode)

(idris-mode
 :repo "idris-hackers/idris-mode"
 :fetcher github
 :files (:defaults "logo-small.png"))

看起来，.emacs文件中的最后一个表达式来自idris-mode的MELPA配方。您不需要在init文件中这样做--只需输入M-x list-packages，在列表中找到idris-mode，然后输入i x安装它。之后，每次启动Emacs时，idris-mode都是可用的。
