Python的devel的荫安装错误

Question

安装蟒-devel的的失败，并附加消息

配置如下： - CentOS的7.2 - Python 2.7版安装

1. 我重新运行与荫负荷在输出中建议使用，并且失败时使用同样的消
2. yum info python ==>已安装的软件包python 2.7.5 34.el7
3. yum info python-devel ==>未安装。可用2.7.5 48.el7
4. yum deplist python-devel ==>依赖于python2.7.5-48.el7
5. 试图安装Python2.7.5-48.el7 wih“yum update python”，它失败与python-devel install相同的错误信息。

Answer 1

删除软件包python-argparse和redhat-upgrade-tool。

然后做了一个yum安装python-devel，这次它成功了。我认为在较早的python 2.6上，这两个软件包有很大的依赖关系。

Answer 2

从百胜文档，这里的处理您的每5个错误的最安全的方式：

首先删除重复项，并运行此之后仍不能解决任何错误：

package-cleanup --cleandupes 

如果上面带有丢失的包清理错误，然后首先运行：

yum install yum-utils 

然后与处理其它4个错误：

yum reinstall grep-* 

其中grep- *是如在错误信息示出的包名称。我在上面的命令中用*缩写了其余的grep版本名称。

重复上面的命令为其他3个被指示为缺失的包。如果百胜命令为您提供了错误，那么尝试一下本作只是一个包：

rpm -ivh --force grep-* 

然后终于从原始的错误消息重新运行百胜命令。

在您要清理剩余的混乱，运行此命令的任何一点：

yum clean all 
package-cleanup --problems 

并遵循的方向。如需进一步参考，请查阅

man yum.conf 

Answer 3

问题是您在CentOS 7上，但安装了CentOS 6软件包。

• 蟒蛇-argparse-1.2.1-2.1.el6.noarch
• 红帽升级工具-1：0.7.22-3.el6.centos.noarch

获取列表所有已安装的el6软件包（rpm -qa | grep el6）并删除它们或将它们更新到它们的el7等价物。你应该能够删除argparse，因为它在2.7标准库中。
