windows – 无法安装emacs el-get包,emacs无法连接到互联网

(add-to-list 'load-path ".emacs.d/el-get/el-get")
(unless (require 'el-get nil t)
  (url-retrieve
   "https://raw.github.com/dimitri/el-get/master/el-get-install.el"
   (lambda (s)
     (end-of-buffer)
     (eval-print-last-sexp))))

我正在使用d：.emacs.d目录中的此代码启动emacs,该目录不在默认位置

set HOME=%~dp0..
cd ..
D:emacs-24.3binrunemacs.exe --debug-init --xrm "emacs.Background: light green"

这应该从github下载包,但我得到这个：

如果emacs实际上是在尝试连接,则防火墙没有通知.
