好久没有之过博客了，一时兴起看看在我新Debian系统下Jekyll还能不能用，于是安装好Ruby，rake，rubygems然后就gem install jekyll，jekyll --server，在firefox中打开localhost:4000开工试下，结果不试不知道，一试还真出问题了:
Forbidden
no access permission to `/'
WEBrik/1.3.1 (Ruby/1.8.7/2010-08-16) at localhost:4000对Ruby完全不懂，用google搜了下，说jekyll --no-auto可以查看一些信息，结果就发现了：

from $GEM_HOME/bin/jekyll:19搜了下 jekyll array (NomethodError) 发现了这里，说是要将category改为categories，结果还真发现管用。私下猜测category是个变量，而categories是个数组或列表这类的东西，而Ruby以[]来限定列表，所以它认为[Jekyll]是个列表，所以它前面要用categories。我又把category保持不变，将[Jekyll]变为Jekyll(去掉[])试了下，也可以，看来猜得还有点谱;)。只是还是有点奇怪，原来怎么就没发现这个问题，而且github显示得也看不出有什么异常，算了，不去深究了，不怎么想学Ruby，其实也是不太愿折腾了。
