NGINX 编译报错及pcre-devel无法安装?报错

一、编译nginx报错：

    ./configure: error: the HTTP rewrite module requires the PCRE library.

    You can either disable the module by using --without-http_rewrite_module

    option, or install the PCRE library into the system, or build the PCRE library

    statically from the source with nginx by using --with-pcre=<path> option.

二、查看pcre  

三、yum安装pcre-devel ：

     yum -y install pcre-devel

    报错Protected multilib versions: pcre-7.8-7.el6.i686 != pcre-7.8-7.kb2.ky3.x86_64

四、添加指令 --setopt=protected_multilib=false

    yum  install pcre-devel  --setopt=protected_multilib=false

    报错

    事务测试出错：

  package pcre-7.8-7.kb2.ky3.x86_64 (which is newer than pcre-7.8-7.el6.i686) is already installed

求大神解救我该怎么安装pcre-devel
