terminal - 安装了 jekyll 但 'command not found'

Question

我安装了 jekyll ，但令人惊讶的是，osx 无法识别其已安装。

$ sudo gem install jekyll
Password:
Successfully installed jekyll-1.2.1
Parsing documentation for jekyll-1.2.1
Done installing documentation for jekyll after 1 seconds
1 gem installed

$ jekyll
-bash: jekyll: command not found

gem environment ( - INSTALLATION DIRECTORY: /usr/local/Cellar/ruby/2.0.0-p247/lib/ruby/gems/2.0.0 )

$ cd /usr/local/Cellar/ruby/2.0.0-p247/lib/ruby/gems/2.0.0/gems/

echo $PATH

/usr/local/bin:/usr/local/sbin:~/bin:/usr/local/bin:/usr/local/sbin:~/bin:/Users/TheSpiritMolecule/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/TheSpiritMolecule/.rvm/bin

我已经安装了 rbenv，我错过的步骤是做一个 rbenv rehash之后 gem install jekyll .重新哈希在 ~/.rbenv/shims 中创建一个链接，该链接包含在 $PATH 中。
