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.安裝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
拷貝一下內容到.vimrc內

4. 下載YouCompleteMe
在用戶家目錄下執(zhí)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 安裝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 下載失敗解決如下：
????進入/etc/resolv.conf。
????修改內容為下
????nameserver 8.8.8.8 #google域名服務器
????nameserver 8.8.4.4 #google域名服務器
????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
路徑與.vimrc中相同 '~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py'?
