Answer 1

我已经找到问题所在了...要在emacs中下载melpa列表（emacs必须访问互联网），因此您必须包括库文件才能执行此操作...从此处下载gnutls-3.3.11-w32-bin https://sourceforge.net/projects/ezwinports/files/ ...提取下载的文件...并将.dll文件放入emacs文件夹中的bin文件中...希望您对我的小帮助感到满意:)

Answer 2

I had this problem. It could be a $PATH issue.

Answer 3

I had the similar issue on Win7 and this answer from stackexchange helped me. In short words you have to download compiled Windows GnuTLS libraries and dependencies from here and unzip it to emacs folder. Get emacs-25-i686-deps.zip if you use 32-bit Windows and get emacs-25-x86_64-deps.zip if you use 64-bit .

Answer 4

For me, since I was using Emacs 25.2 64-bit, I had to download the emacs-25-x86_64-deps.zip files from here:

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