yum 重复安装问题

** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows:

python-2.6.6-37.el6_4.x86_64 is a duplicate with python-2.6.5-3.el6.x86_64

----------------------------------------

重复安装？？？

要解决上述问题，可以这样:

# 首先安装 yum-utils 套件
　　
　　yum install yum-utils
　　
# 执行 clean duplicate package
　　
　　package-cleanup --cleandupes

  Duplicate Package Options:
    --dupes             Scan for duplicates in your rpmdb
    --cleandupes        Scan for duplicates in your rpmdb and remove older
    --noscripts         disable rpm scriptlets from running when cleaning
                        duplicates
