我按照Jekyll中的所有说明操作：
gem install jekyll bundler
jekyll new my-awesome-site
cd my-awesome-site
bundle install
bundle exec jekyll serve
然后，当我浏览到http://localhost:4000时，命令提示符中有一个空白页面和以下错误：
Error reading file C:/Ruby23/lib/ruby/gems/2.3.0/gems/minima-1.2.0/_layouts/default.html: No such file or directory @ rb_sysopen - /Ruby23/lib/ruby/gems/2.3.0/gems/minima-1.2.0/_layouts/default.html

这种情况正在发生，因为我在分区D:中使用Jekyll，而Ruby安装在分区C:中。事实上，如果我在一个分区中安装所有分区都没有错误，但我更喜欢将所有项目保留在分区D:中。我认为问题出在rb_sysopen。
任何解决方案？感谢。
这是我的Gemfile.lock：

，_includes，_layouts从主题_sass的安装目录复制到项目目录，即C:\Ruby23\lib\ruby\gems\2.3.0\gems\minima-1.2.0。
Jekyll将首先检查项目目录中主题的文件。
当然这只是一种解决方法。
