1. 移除vim
sudo apt-get remove vim vim-runtime gvim
sudo apt-get remove vim-tiny vim-common vim-gui-common vim-nox
2.安装vim
sudo apt-get update
sudo apt-get install vim
sudo apt-get install build-essential cmake python3-dev
3.配置.vimrc
cd ~
vim .vimrc
拷贝一下内容到.vimrc内

4. 下载YouCompleteMe
在用户家目录下执行命令：git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
git clone https://github.com/Valloric/YouCompleteMe.git ~/.vim/bundle/YouCompleteMe
5.1 安装Youcomplete
cd ~/.vim/bundle/YouCompleteMe
git submodule update --init --recursive
./install.py --clang-completer
5.2如果遇到libclang-10.0.0-x86_64-unknown-linux-gnu.tar.bz2 下载失败解决如下：
进入/etc/resolv.conf。
修改内容为下
nameserver 8.8.8.8 #google域名服务器
nameserver 8.8.4.4 #google域名服务器
cd ~/.vim/bundle/YouCompleteMe/third_party/ycmd/clang_archives
mv libclang-7.0.0-x86_64-unknown-linux-gnu.tar.bz2 libclang-7.0.0-x86_64-unknown-linux-gnu.tar.bz2.old
wget https://dl.bintray.com/micbou/libclang/libclang-7.0.0-x86_64-unknown-linux-gnu.tar.bz2
6. 配置ycm_extra_conf.py
路径与.vimrc中相同 '~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py'
