在windows上安装gem puma时出错

Question

尝试安装gem puma的第一步是在命令提示符中输入gem install puma --version2.12.3。然后出现此错误。我不知道该怎么理解它。

C:\Users>gem install puma --version 2.12.3
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing puma:

        --with-cryptolib
        --without-cryptolib
        --with-libeay32lib
        --without-libeay32lib

extconf failed, exit code 1

Gem files will remain installed in C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/puma-2
.12.3 for inspection.

一旦我收到这封信，我就会按照下面的指示https://github.com/hicknhack-software/rails-disco/wiki/Installing-puma-on-windows

我收到了这个错误：

C:\Users>gem install puma -- --with-opt-      dir=c:\
openssl
ERROR:  Loading command: install (LoadError)
        127: The specified procedure could not be found.   - C:/Ruby22-x64/lib/r

ERROR:  While executing gem ... (NoMethodError)

附注:这是mkmf.log

请帮帮我！谢谢!

我想我已经找到你问题的答案了。Here the link

您必须下载OpenSSL库。有两种类型的OpenSSL库，一种用于32位，另一种用于64位。

安装它们后，运行gem install puma -- --with-opt-dir=D:\openssl

--with-opt-dir=D:\openssl是您下载lib的文件夹方向。

有些教程有指向openssl的链接，openssl是用于32位计算机的。在几次失败之后，我意识到了这一点。然后我已经下载了64位版本。
