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
