Install YCM on Ubuntu 14.04:
sudo apt install build-essential cmake
sudo apt install python-dev python3-dev
# Add `Plugin 'Valloric/YouCompleteMe'` into .vimrc.
vim +PluginClean +PluginInstall
cd ~/.vim/bundle/YouCompleteMe
./install.py
Take about one hour (16:44 ~ 17:44 ) when running vim +PluginClean +PluginInstall
(about 200MB for the repo).
If your vim version is lower than 7.4.143, you must install a newer version vim:
sudo add-apt-repository ppa:pkg-vim/vim-daily
sudo apt-get update
sudo apt-get install vim
dpkg -s vim | grep 'Version' # should be greater than 7.41
Or the following error occurs:
Error detected while processing function youcompleteme#Enable..<SNR>74_OnBufferRead:
line 17:
