vim 8 IDE 开发环境配置
1、升级 vim 到最新版本 ：vim8.2.2028
wget -O vim8.2.2028.zip https://github.com/vim/vim/archive/v8.2.2028.zip unzip vim8.2.2028.zip cd vim-8.2.2028/ cd src/ mkdir /usr/local/vim8
编译vim，支持 python3
./configure --with-features=huge --enable-multibyte --enable-cscope --enable-python3interp=yes --with-python-config-dir=/usr/lib64/python3.6/config-3.6m-x86_64-linux-gnu --prefix=/usr/local/vim8/ --with-python3-command=/usr/bin/python3 cp bin/vim /usr/bin/vim cp bin/vim /usr/local/bin/vim
2、安装 cmake
wget https://github.com/Kitware/CMake/releases/download/v3.19.0/cmake-3.19.0-Linux-x86_64.tar.gz
最新版不需要编译，直接可以使用
mv cmake-3.19.0-Linux-x86_64 /usr/local/cmake echo 'export PATH=/usr/local/cmake/bin:$PATH' >> .zshrc source ~/.zshrc
3、安装vimplus
git clone https://github.com/chxuan/vimplus.git cd ./vimplus ./install.sh
4、配置 .vimrc

5、安装YouCompleteMe
vimplus自动安装好之后 YouCompleteMe在系统的 ~/.vim/plugged/YouCompleteMe 路径下
先删除之前装的YouCompleteMe目录：
rm -rf ~/.vim/plugged/YouCompleteMe
从git上拉取YouCompleteMe
git clone https://github.com/Valloric/YouCompleteMe.git ~/.vim/plugged/YouCompleteMe #很慢 cd ~/.vim/plugged/YouCompleteMe git submodule update --init --recursive #很慢
等待下载完毕，执行安装命令
./install.py --clang-completer
