执行vim的error信息：

root@yang:~# vim

Press ENTER or type command to continue

只需要重新编译vim时，加入如下参数编译：

./configure --enable-pythoninterp=yes --enable-cscope --enable-fontset --with-python3-config-dir=/usr/lib/python3.6/config-3.6m-x86_64-linux-gnu --enable-python3interp=yes --with-python3-command=python3.6
make
make install

cp /usr/local/bin/vim /usr/bin/vim
