本机环境配置信息如下：

Answer 1

亲，我的解决了，结合我的不断重复的过程，问题出在了MYSYS2和bundle这两个身上，我跟你大致说一下我的安装过程及一些注意点（最重要的点就是所有安装目录最好不好出现空格）：
1、安装ruby，根据你的教程，无脑点就行，但是有个注意点，安装的路径中，连同命名，不要出现空格！！！
2、ruby安装完，会出现有个选项，让你安装MSYS2这个东东，如果没有勾选，后面自己打开cmd，输入“ridk install”进行MSYS2的安装，会出现然你选择123，你选3就行。这个过程会下载很多安装包什么的，耐心等待，一定要耐心，要完整装完才行，装好会让你再做一次123选择，这个时候不需要选了，直接enter退出就行了。
3、安装DevKit，在官网下载DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe，然后点击运行，同样，安装目录不要出现空格，可以百度这个相关的安装，还是比较简单的
4、然后安装RubyGems，从官网下载压缩包，解压到你想要的目录下，路径不要有空格，然后cmd命令指到这个文件夹下面，输入“ruby setup.rb”执行安装，同样也可百度
5、安装bundler，输入“gem install bundler”执行安装
6、上面的安装基本缺一不可，然后就可以安装jekyll了，执行“gem install jekyll”，最后成功了。

我也是在重复安装卸载安装的过程中，最后成功了，jekyll的要求比较高，所以该有的环境都不能漏，这是我的做法，给你参照下，一次不行就多次，有一点遗漏最好就重新整个过程，不然补这个补那个的最后很容易面目全非，做了无用功。。
