每当我尝试在 CentOS 6.7 中安装 python33 时，我都会收到以下错误消息。

sudo yum install python33

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我习惯了 ubuntu，其中 apt-get 似乎工作得很好。我认为 yum 应该有点相似。它不应该也只查找并下载依赖项吗？

不管怎样，我有一个全新的 CentOS 6.7 系统(带有最近的 yum upgrade):

[root@b854039a02fe /]# cat /etc/centos-release 
CentOS release 6.7 (Final)

默认的存储库集中没有python33包:

[root@b854039a02fe /]# yum install python33
Loaded plugins: fastestmirror
Setting up Install Process
Determining fastest mirrors
 * base: mirror.atlanticmetro.net
 * extras: mirror.atlanticmetro.net
 * updates: ftp.usf.edu
No package python33 available.

显然有 an SCL repository使用 python33，所以:

[root@b854039a02fe /]# yum install centos-release-SCL

然后:

[root@b854039a02fe /]# yum install python33
[...]

Complete!

也许您指向的特定存储库镜像不完整。考虑运行:

yum clean all

然后重试。
