我的Jekyll网站停止了生成.当我启动Jekyll时,我得到了rdiscount缺少的依赖错误:

~/src/markcerqueira.github.com [source] jekyll serve --watch

  Dependency Error:  Yikes! It looks like you don't have rdiscount or one of its dependencies installed. In order to use Jekyll as currently configured,
                     you'll need to install this gem. The full error message from Ruby is: 'cannot load such file -- rdiscount' If you run into trouble,

已安装rdiscount:

~/src/markcerqueira.github.com [source] gem list rdiscount

不确定为什么这个修复它,但运行bundle clean和bundle update修复了这个问题.

~/src/markcerqueira.github.com [source] sudo bundle clean --force
~/src/markcerqueira.github.com [source] bundle update
~/src/markcerqueira.github.com [source] jekyll serve --watch

也许json gem造成了一些问题？
