vim – YouCompleteme有效,但无法使用TAB完成

./install.sh --clang-completer

这就是我的vimrc的样子：

syntax on
set expandtab
set cindent
set tabstop=4
retab
set shiftwidth=4
set hlsearch
set paste
set ic
set number
colorscheme molokai
set t_Co=256

set nocompatible              " be iMproved,required
filetype off                  " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()

Plugin 'gmarik/Vundle.vim'
Plugin 'tpope/vim-fugitive'
Plugin 'tpope/vim-repeat' 
Plugin 'kien/ctrlp.vim'
Plugin 'sjl/gundo.vim'
Plugin 'Valloric/YouCompleteMe'
Plugin 'scrooloose/syntastic'
Plugin 'Valloric/ListToggle'

call vundle#end()            " required


filetype plugin indent on 

"options for syntastic"

"Gundo options"

nnoremap <F5> :GundoToggle<CR>

"CtrlP options"
let g:ctrlp_map = '<c-p>'
let g:ctrlp_cmd = 'CtrlP'

"Powerline stuff"
python from powerline.vim import setup as powerline_setup
python powerline_setup()
python del powerline_setup

set laststatus=2

YCM有效但我无法使用TAB切换建议,仅使用向下和向上箭头并使用回车接受.

为什么会这样？另一个程序是否使用TAB键？

非常感谢您的帮助
