Rails requires RubyGems >= 1.3.2 (you have 1.3.1). Please `gem update --system` and try again.

ERROR:  While executing gem ... (RuntimeError)
    gem update --system is disabled on Debian. RubyGems can be updated using the official Debian repositories by aptitude or apt-get.

【解决方案1】：

好像你从 Debian/apt-get 包中安装了 rubygems。

如果您使用的是 Ubuntu 9.04 或更高版本，这可能有效：

sudo gem install rubygems-update
sudo update_rubygems

否则，请删除软件包并从源代码安装 rubygems，无论如何这是安装 rubygems 的推荐方式：

sudo apt-get remove rubygems
wget http://rubyforge.org/frs/download.php/60718/rubygems-1.3.5.tgz
tar xzvf rubygems-1.3.5.tgz
cd rubygems-1.3.5
sudo ruby setup.rb
sudo ln -s /usr/bin/gem1.8 /usr/bin/gem
sudo gem update --system
