用vim 7.4.4版本裝YouCompleMe的時候提示這樣的信息:
YouCompleteMe unavailable: requires Vim 7.4.1578+。明明版本比它要求的還高，居然還會報錯，網上搜了一下說需要升級vim到8.0版本，大都需要用到sudo命令，但是我的是在服務器上，我並沒有sudo權限，所以可以考慮將vim安裝在local，安裝步驟如下：
I. Install the Vim 8.0 with Make
1. Install the necessary package.
$ sudo yum install gcc-c++ ncurses-devel python-devel
2. Get the source code of Vim.
$ git clone https://github.com/vim/vim.git
3. Go to build directory.
$ cd vim/src && git check v8.0.1522
Use the version like my MacVim.
4. Configure it !
$ ./configure \
--disable-nls \
--enable-cscope \
--enable-gui=no \
--enable-multibyte \
--enable-pythoninterp \
--enable-rubyinterp \
--prefix=/home/jonny/.local/vim \
--with-features=huge \
--with-python-config-dir=/usr/lib/python2.7/config \
--with-tlib=ncurses \
--without-x
注意上面的一些參數需要做對應的修改：
--prefix: 需要改成local user路徑--with-python-config-dir:我用的是anaconda，然后我的/home/anaconda3/lib/python3.7路徑下並沒有config文件夾，這個文件夾是用來支持YouCompleteMe插件的，所以你可以先手工創建這個文件夾即可。
5. Compile and install the Vim.
$ make && make install
6. Add ~/.local/vim/bin/ into $PATH.
$ vim ~/.bashrc
...
if [ -d "$HOME/.local/vim/bin/" ] ; then
PATH="$HOME/.local/vim/bin/:$PATH"
fi
7. Reload the bashrc.
source ~/.bashrc
8. Check Vim version
輸入$ vim --version你就會看到此時vim版本變成了8.0.
II. Install the YouCompleteMe plugin
- Install the necessary package.
$ sudo yum install gcc-c++ cmake python-devel
- Get the YouCompleteMe plugin.
$ mkdir ~/.vim/bundle && git clone https://github.com/Valloric/YouCompleteMe.git ~/.vim/bundle/YouCompleteMe
- Compile and install the YouCompleteMe.
$ cd ~/.vim/bundle/YouCompleteMe && python ./install.py
安裝完YouCompleteMe之后，每次打開一個文件都會提示這樣的信息
Found /Users/username/.ycm_extra_conf.py. Load?
(Question can be turned off with options, see YCM docs)
[O]k, (C)ancel
可以在.vimrc文件中添加如下命令即可關閉提示
let g:ycm_confirm_extra_conf = 0
Enjoy it.
感謝: Install the Vim 8.0 and YouCompleteMe with Make on CentOS 7.4
