我正在尝试将 Marmalade 添加为包源，但是当我这样做时出现错误：Symbol's value as variable is void: package-archives.有人知道如何解决这个问题吗？下面是我的.emacs文件。
;;; This was installed by package-install.el.
;;; This provides support for the package system and
;;; interfacing with ELPA, the package archive.
;;; Move this code earlier if you want to reference
;;; packages in your .emacs.
(when
(load
(expand-file-name "~/.emacs.d/elpa/package.el"))
(package-initialize))
(add-to-list 'load-path (expand-file-name "~/.emacs.d"))
(add-to-list 'load-path "~/.emacs.d/plugins")

(package-initialize)
安装 package.el
我运行了以下代码：
(let ((buffer (url-retrieve-synchronously
"http://tromey.com/elpa/package-install.el")))
(save-excursion
(set-buffer buffer)
(goto-char (point-min))
(re-search-forward "^$" nil 'move)
(eval-region (point) (point-max))
(kill-buffer (current-buffer))))
