在Emacs 24.3中安装用于管理包的el-get

Question

安装el-get的说明如下：

;; Copy/paste this code into your *scratch* buffer,
;; hit C-j, and you have a working el-get.
(url-retrieve
 "https://raw.github.com/dimitri/el-get/master/el-get-install.el"
 (lambda (s)
   (goto-char (point-max))
   (eval-print-last-sexp)))

当我这样做时，在debugger-mode中打开一个名为*Backtrace*的缓冲区，其中包含以下内容：

Debugger entered--Lisp error: (void-variable closed)
  eval(closed nil)
  eval-last-sexp-1(t)
  eval-last-sexp(t)
  eval-print-last-sexp()
  (lambda (s) (goto-char (point-max)) (eval-print-last-sexp))(nil)
  apply((lambda (s) (goto-char (point-max)) (eval-print-last-sexp)) nil)

我是否认为文件https://raw.github.com/dimitri/el-get/master/el-get-install.el中存在错误？或者，为了让这样的脚本正常工作，我还需要进行其他设置吗？

Answer 1

不知何故，下载的文件被附加了一个closed行，这在原始文件中并不存在--不知道为什么，这在我身上不会发生。它在回溯的最后是可见的。

您可以复制整个el-get-install.el文件，粘贴到*scratch*中，然后使用C-j对其求值。
