vim的YouCompleteMe补全插件的vimrc和yum_extra_conf.py文件怎么配置(开发python)

Question

按照网上的教程，配置了vim的YouCompleteMe插件，但是安装之后，用来开发python跟本不会提示，，

后来看到说需要配置vimrc和yum_extra_conf.py这两个文件，请教下需要怎么配置？
我的当前的.vimrc文件如下：

set nocompatible                " be iMproved
filetype off                    " required!
set rtp+=~/.vim/bundle/vundle/
call vundle#rc()

" let Vundle manage Vundle
Bundle 'gmarik/vundle'

"my Bundle here:

Answer 1

需要安装clang

Answer 2

题主也没说os，作为一般性的建议把当初自己的安装日志ctrl+c & ctrl+v一遍。如果能提供vim的相关运行信息，例如:version,:YcmDebugInfo，回复也就能更有针对性。

• archlinux installation

    pacman -S cmake clang
    cd ~
    mkdir ycm_build && cd ycm_build
    cmake -G "Unix Makefiles" -DUSE_SYSTEM_LIBCLANG=ON . ~/.vim/bundle/YouCompleteMe/cpp
    make ycm_support_libs
    #remove libclang.so, or keep it if you compiled clang manually.
    rm ~/.vim/bundle/YouCompleteMe/python/libclang.so

• windows pre-build installation

  1. install python2.7 for python27.dll
  2. compile vim with python support, opt to download the pre-build release: Vim for windows
  3. follow the instruction from Vim YouCompleteMe for Windows

PS: yum_extra_conf.py的配置只是针对C/C++的，对python来说不需要。

Answer 3

试试显式指明路径?

let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py'

Answer 4

可以把 .ycm_extra_conf.py 放项目目录里
