Emacs软件包安装是否要插入破折号? [英] Emacs package-install inserting extra dash?

问题描述

我正在尝试自动安装所有依赖项以进行新的Emacs安装.当我将以下代码段放入.emacs中时，我会不断得到:Package `smex-' is unavailable.

I'm trying to have all of my dependencies install automatically for a new Emacs install. When I put the snippet below in my .emacs I keep getting: Package `smex-' is unavailable.

我想知道这是否是预期的功能? Emacs入门套件做了类似的事情，我记得以前曾经做过.使用Emacs 24.3.

I was wondering if this is expected functionality? The Emacs starter-kit did something similar which I remember working before. Using 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))))

EDIT

显然，这是由错误或其他原因引起的.我现在能够在最新的Emacs 24.3.1中使它工作.显然他们也进行了更改，因此程序包名称应为符号.

Apparently this was caused by a bug or something. I was able to get it to work now in latest Emacs 24.3.1. Apparently they've also changed it so that package names should be symbols.

(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)))

推荐答案

请参见package-compute-transaction:

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