下载：
wget ftp://ftp.vim.org/pub/vim/unix/vim-7.3.tar.bz2
tar jxf vim-7.3.tar.bz2
在7.3的包中的src中./configure出现如下错误：
checking for stack_t... yes
checking whether stack_t has an ss_base field... no
checking --with-tlib argument... empty: automatic terminal library selection
checking for tgetent in -lncurses... no
checking for tgetent in -ltermlib... no
checking for tgetent in -ltermcap... no
checking for tgetent in -lcurses... no
no terminal library found
checking for tgetent()... configure: error: NOT FOUND!
You need to install a terminal library; for example ncurses.
Or specify the name of the library with --with-tlib.
解决方案：
sudo apt-get install libncurses5-dev
然后继续
make
sudo make install
这样就成功升级到7.3了。
Ctrl+Shift+n 重新打开一个终端
vim 回车，即可看到7.3版本了。
