Emacs包安装插入额外的破折号？

Question

我正在尝试将所有依赖项自动安装到新的Emacs安装中.当我把下面的片段放在我的.emacs中时,我会继续:Package `smex-' is unavailable.

我想知道这是否是预期的功能？Emacs入门套件做了类似我记得以前工作的东西.使用Emacs 24.3.

(when (not package-archive-contents)
  (package-refresh-contents))

(defvar my-packages
  '(smex))

(dolist (p my-packages)
  (let ((s (symbol-name p)))
    (when (not (package-installed-p s))
      (package-install s))))

编辑

显然这是由一个bug或其他东西引起的.我现在能够在最新的Emacs 24.3.1中使用它.显然他们也改变了它,所以包名应该是符号.

(package-initialize)

(when (not package-archive-contents)
  (package-refresh-contents))

(defvar my-packages
  '(list of packages))

(dolist (p my-packages)
  (when (not (package-installed-p p))
    (package-install p)))

Answer 1

我在使用时遇到了这个问题

(add-to-list 'package-archives 
             '("melpa" . "http://melpa.milkbox.net/packages/"))

打电话后(package-initialize).如果我执行

(setq package-archives '(("melpa" . "http://melpa.milkbox.net/packages/")
                         ("gnu" . "http://elpa.gnu.org/packages/")))

之前(package-initialize),自动安装逻辑可以安装缺少的包.

看package-compute-transaction：

(error "Package `%s-%s' is unavailable"
       (symbol-name next-pkg)
       (package-version-join next-version))
