【已解决】Win10下安装求助:Could not create connection to github.com:443

[Dusty]

安装后第一次启动，终于到达了spacemacs的欢迎界面，而且空格键也能呼出菜单，但下方出现如此提示：

Errors:
    - Error: Cannot find gzip executable in you PATH. Download and install gzip here:
      http://gnuwin32.sourceforge.net/packages/gzip.htm spacelpa installation has been
      skipped!

之后我按照提示，下载并安装gzip，并将安装目录加入Path变量，之后就出现如下提示

经过百度后，我下载了gnutls-3.4.15-w32-bin.zip，并将压缩包bin目录中的所有dll文件拷贝至EMACS安装目录下的bin目录中，之后重启EMACS，依然有以上提示。

PS：网络环境应该是可以的，用macbook不挂代理安装，并无以上提示。

解决方法：
基本思路是引GnuTLS的库文件或者Emacs官方的。 方法一：
GnuTLS官网 → Download → GnuTLS for Windows → 下载最新版压缩包 → 将包中bin目录下dll解压至emacs.exe所在目录 → 重启emacs

方法二：
Emacs官网 → Download → 找到 Windows → nearby GNU mirror → 搜索deps，下载最新版压缩包(这次我下载的是emacs-25-x86_64-deps.zip) → 将包中bin目录下dll解压至emacs.exe所在目录 → 重启emacs
PS:现在想想，这个下载的emacs应该可以直接使用，我很残地选择了转移dll。。。

我建议选择方法二，也就是引官方提供的库文件，因为可以正常显示图标。另外值得注意的是，我使用的不是 Emacs-26 的包，而是正常下载目录中的有deps的包。

时间允许的话，希望后来的同学能完整阅读下方的回复，也许能有额外的收货。

Emacs 26 win32 官方包有比较大的变化， 大家可以了解一下

主要的变化是和依赖包一起打包了。 https://alpha.gnu.org/gnu/emacs/pretest/windows/README-windows-binaries

直接下有ｄｅｐｓ的试试。

[JJPandari]

gnutls所在的文件夹在path里面了吗？

[dj_lial]

在ftp://ftp.gnutls.org/gcrypt/gnutls/w32/ 下载最新版的The GnuTLS Transport Layer Security Library， 将bin目录下文件全部解压出来，放在emacs\bin 目录下可解决。emacs 启动时的"gnutls.c:[1] (Emacs) GnuTSL libarary not found"也一并消除。

[clloz]

同样遇到这个问题，求解答

[JJPandari]

试过下载gnutls exe了么？或者openssl也行。我的spacemacs里：

tls-program is a variable defined in `tls.el'.
Its value is

("gnutls-cli --x509cafile %t -p %p %h" "gnutls-cli --x509cafile %t -p %p %h
--protocols ssl3" "openssl s_client -connect %h:%p -no_ssl2 -ign_eof")

[clloz]

下载了，gnutls的bin也加到path里面了，不过还是报错

[kingdemonccgg]

我刚更新完也是这个问题,但是我重启了几次就好了.重启emacs.还有我用的7z的压缩软件.

[clloz]

google了半天也没找到解决办法，果然windows上还是有点蛋疼，主要不清楚什么原因导致的，mac上就没这么多问题。

[clloz]

这里，这个链接上面写了应该是缺什么dll，我就下载了emacs-26.0.90-x86_64.zip把bin里面的dll都复制到了我的emacs的bin文件夹里面，就好了，这个里面dll很多，我也不知道具体哪个有用，复制完重启的时候会卡一会儿，你们试试看有没有用，我这里是好了。

我希望能发布个完善的答案，所以Emacs-26 的链接引自哪个页面，还请告知，谢谢。我在官网上找了一下，可能由于不够仔细+英文超烂，没有找到 @clloz @sujikinen

[clloz]

就是这个页面，我下的是emacs-26.0.90-x86_64.zip，出处就是这个问题的答案里面，我是直接从这个问题下面的链接进去的。
