Question

我正在使用emacs 24.5，我正在尝试将melpa存档添加到emacs到我的包存档。当我尝试M-x list-packages时，我无法下载melpa存档，并且没有出现melpa repo的软件包列表。这是我在尝试M-x toggle-debug-on-error

时得到的

Debugger entered--Lisp error: (error "Could not create connection to melpa.org:443")
signal(error ("Could not create connection to melpa.org:443"))

和我的.emacs文件

(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.

Answer 1

我找到问题的确切位置...在emacs中下载melpa列表（emacs必须访问互联网）所以你必须包含库文件才能做到这一点...下载 gnutls-3.3.11 -w32-bin 从这里https://sourceforge.net/projects/ezwinports/files/ ...解压缩下载的文件...并将.dll文件放在emacs文件夹中的bin文件中... 希望你对我的小帮助感到高兴:)

Answer 2

我有这个问题。这可能是一个$ PATH问题。

Answer 3

我在Win7上有类似的问题，来自stackexchange的this回答帮助了我。简而言之，您必须从here下载已编译的Windows GnuTLS库和依赖项，并将其解压缩到emacs文件夹。如果您使用emacs-25-i686-deps.zip Windows，请获取32-bit，如果您使用emacs-25-x86_64-deps.zip，则获取64-bit。

Answer 4

对我来说，由于我使用的是64位Emacs 25.2，因此我必须从此处下载arr = ["5b608c0769698c3990c64ef4"]文件：

https://ftp.gnu.org/gnu/emacs/windows/emacs-25/

无法下载melpa存档
