如何在Windows上安装ruby gem puma

Question

Welcome, gather around.

My first step when trying to install the gem puma is to enter gem install puma --version 2.12.3 into my command prompt. Then this error appears. I don't know what to make of it.

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:
        ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:
        --with-opt-dir
        --without-opt-dir
        --with-opt-include

        --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.

Please help, thank you!

You probably just need OpenSSL, but be warned that some gems just fail to work on Windows.
