\printbibliography 始终为空白（给出警告）

Question

我无法使用 biblatex 生成参考书目。甚至最基本的示例都不起作用。

\documentclass{article} 

\usepackage{filecontents}

\begin{filecontents*}{refs.bib}
@BOOK
    {KandR,
     AUTHOR  = "Kernighan, Brian W. and Ritchie, Dennis M.",
     TITLE   = "{The C Programming Language Second Edition}",
     PUBLISHER = "Prentice-Hall, Inc.",
     YEAR = 1988
    }
\end{filecontents*}

\usepackage{biblatex} 
\addbibresource{refs.bib} 

\begin{document} 

Hello \cite{KandR}
\printbibliography 

\end{document}

据我了解，我在文件（test1.tex）上运行以下命令：

pdflatex test1        (This gets some warnings, but ignore)
biber test1
pdflatex test1

biber 给出警告：

WARN - Warning: Found biblatex control file version 2.5, expected version 2.3

第二个 pdflatex 命令给出警告：

LaTeX Warning: Citation 'KandR' on page 1 undefined on input line 20.
LaTeX Warning: Empty bibliography on input line 21.
LaTex Warning: There were undefined references. 

我已经尝试了几件事：

• 使用 bibtex 命令可以得到：

  The top-level auxiliary file: test1.aux
  I found no \citation commands---while reading file test1.aux
  I found no \bibdata command---while reading file test1.aux
  I found no \bibstyle command---while reading file test1.aux
  

• 使用 [backend=biber] 不会改变任何东西

一些说明：

• Windows 8
• MikTex 2.9

• 特克斯沃克斯

我尝试使用后端来编写此代码biber。对于编译，我使用xelatex和UTF 格式对于所有文件：

\documentclass{article} 

\usepackage{filecontents}
\usepackage[backref=true,                % 
            hyperref=true,               % 
            firstinits=true,             %
            indexing=true,               %
            url=false,                   % 
            style=alphabetic,            %  style=debug, alphabetic
            backend=biber,               % 
            doi=false,
            texencoding=utf8,
            bibencoding=utf8]{biblatex}
\usepackage{hyperref}
\hypersetup{pdfauthor={Your name},
            pdftitle={Your article},
            pdfsubject={My study notes},
            pdfkeywords={linear algebra, math, physics, electronics},
            pdfpagelayout={TwoPageLeft}, % Displays two pages, odd-numbered pages to the left 
            pdfcreator={Xelatex}
            bookmarks={true},            %  A set of Acrobat bookmarks are written
            colorlinks={true},           %  Colors the text of links and anchors. 
            anchorcolor={black},         %  Color for anchor text.
            filecolor={cyan},            %  Color for URLs which open local files.
            menucolor={red},             %  Color for Acrobat menu items.
            runcolor={blue}              %  Color for run links (launch annotations).        
           }           
\addbibresource{refs.bib}    
\usepackage{biblatex} 
\addbibresource{refs.bib} 

\begin{document} 

Hello \cite{KandR}
\printbibliography 

\end{document}

请检查文件扩展名是否为桶存在且大小不为零。如果此文件大小为零或不存在，请尝试手动创建它。使用命令行并输入以下内容：
