Vundle未正確安裝

Question

好像並非所有的插件都正確安裝。我有以下的日誌文件：

[2015-09-30 14:58:32] Plugin user/L9                  |~

[2015-09-30 14:58:33] Helptags: 4 plugins processed    

我的.vimrc文件是這樣的：

set nocompatible    " be iMproved, required 
filetype off     " required 

set rtp+=~/.vim/bundle/Vundle.vim 
call vundle#begin() 
" let Vundle manage Vundle, required 
Plugin 'VundleVim/Vundle.vim' 
" plugin on GitHub repo 
Plugin 'tpope/vim-fugitive' 
" plugin from http://vim-scripts.org/vim/scripts.html 
Plugin 'L9' 
" Git plugin not hosted on GitHub 
Plugin 'git://git.wincent.com/command-t.git'  
Plugin 'rstacruz/sparkup', {'rtp': 'vim/'} 
" Avoid a name conflict with L9 
Plugin 'user/L9', {'name': 'newL9'} 

call vundle#end()   " required 
filetype plugin indent on " required 

其明顯沒有https://github.com/user/L9頁面，但我不能肯定它是什麼，我做錯了。它在失敗之前請求我的github用戶名和密碼。

更重要的是我需要擔心這個錯誤嗎？
