[root@localhost ~]# which vim
/usr/bin/vim
[root@localhost ~]# rpm -qf /usr/bin/vim
vim-enhanced-7.4.160-1.el7.x86_64
[root@localhost ~]#rm -f /usr/bin/vim    #  -------------------> 删除vim命令，模拟命令错误

 ls -l /usr/bin/vim

#开始重新下载安装vim命令：

 wget ftp://ftp.vim.org/pub/vim/unix/vim-7.4.tar.bz2 
 tar fx vim-7.4.tar.bz2 
 cd vim74/
 yum -y install ncurses-devel ncurses   # -----------------> 要先安装这个库，否则下面的编译会报错!!!!!!!!!!!!!!
 ./configure --prefix=/usr/local/vim74
 make
 make install
 vim
 /usr/local/vim74/bin/vim /etc/profile   # ------------------> 末行添加: PATH=$PATH:/usr/local/vim74/bin/vim;export
 
# 用别名也可以：
# alias vim=‘/usr/local/vim74/bin/vim‘
 source /etc/profile
 echo $PATH
 vim
 vim /etc/profile
