Python-devel yum安装错误

Question

安装python-devel失败并附带消息

配置如下：   - CentOS 7.2   - 安装了Python 2.7

1. 我按照输出中的建议重新运行了yum load，但它失败并显示相同的消息。
2. yum info python ==＆gt;安装包python 2.7.5 34.el7
3. yum info python-devel ==＆gt;未安装。可用2.7.5 48.el7
4. yum deplist python-devel ==＆gt;依赖于python2.7.5-48.el7
5. 尝试使用“yum update python”安装Python2.7.5-48.el7，它失败并显示与python-devel install相同的错误消息。

Answer 1

从yum文档中，这是处理每个错误的最安全方法：

首先删除重复项并在运行此项后解决所有错误：

package-cleanup --cleandupes

如果以上内容缺少包清除错误，请先运行：

yum install yum-utils

然后用以下内容解决其他4个错误：

yum reinstall grep-*

其中grep- *是错误消息中显示的包名称。我在上面的命令中用*缩写了grep版本名称的其余部分。

对指示为缺失的其他3个包重复上述命令。如果yum命令给你错误，那么只针对那个包尝试：

rpm -ivh --force grep-*

然后最后从原始错误消息重新运行yum命令。

在任何时候你想清理剩余的混乱，运行这个命令：

yum clean all
package-cleanup --problems

按照说明操作。有关进一步参考，请使用

查找文档

man yum.conf

Answer 2

删除了包python-argparse和redhat-upgrade-tool。

然后做了一个yum install python-devel并且这次成功了。我认为旧版python 2.6上的这两个软件包存在硬依赖性。

Answer 3

问题是您使用的是CentOS 7，但安装了CentOS 6软件包。

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

获取所有已安装的el6软件包（rpm -qa | grep el6）的列表并将其删除或将其更新为el7等效软件包。您应该能够删除argparse，因为它在2.7标准库中。
