因为Ubuntu15.04系统自带Vim不支持Lua，所以得自己编译安装。

1.卸载系统自带的vim.

$ sudo apt-get remove vim vim-runtime  vim-tiny vim-common vim-gui-common
$ sudo apt-get purge vim vim-runtime  vim-tiny vim-common vim-gui-common

2.安装依赖文件。

$ sudo apt-get install luajit libluajit-5.1 libncurses5-dev libgnome2-dev libgnomeui-dev libgtk2.0-dev libatk1.0-dev libbonoboui2-dev libcairo2-dev libx11-dev libxpm-dev libxt-dev python-dev ruby-dev mercurial

3.下载vim代码。

$ cd /tmp
$ git clone https://github.com/vim/vim.git

4.编译安装。

$ ./configure --with-features=huge \
--enable-cscope \
--enable-rubyinterp \
--enable-largefile \
--disable-netbeans \
--enable-pythoninterp \
--with-python-config-dir=/usr/lib/python2.7/config \
--enable-perlinterp \
--enable-luainterp \
--with-luajit –enable-fail-if-missing \
--with-lua-prefix=/usr \
--enable-gui=gnome2 --enable-cscope --prefix=/usr

$　make VIMRUNTIMEDIR=/usr/share/vim/vim74
$　sudo make install
