我有一个 CentOS 6.0 虚拟机。我正在尝试在其上安装 cloud-init（与 AWS 相关）。我跑
yum install cloud-init
然后，我看到 cloud-init 依赖于许多 python 包。
在我接受安装（带有“y”）后，我看到了数百个这样的错误：
file /usr/lib64/python2.6/xml/etree/ElementPath.pyc from install of python-libs-2.6.6-66.el6_8.x86_64 conflicts with file from package python-2.6.5-3.el6_0.2.x86_64
file /usr/lib64/python2.6/xml/etree/ElementPath.pyo from install of python-libs-2.6.6-66.el6_8.x86_64 conflicts with file from package python-2.6.5-3.el6_0.2.x86_64

usr/bin/python -V 返回 Python 2.6.5，所以看起来虚拟机使用的是这个版本，依赖项使用的是 2.6.6。但是——我不明白为什么当系统使用 2.6.5 时 cloud-init 不能只使用 2.6.6。为什么 cloud-init 安装失败并出现“与文件冲突”错误？
