Python-devel yum 安装错误

Question

python-devel 的安装失败并附加消息

配置如下:
- CentOS 7.2
- 安装了 Python 2.7

我按照输出中的建议使用 yum load 重新运行，但失败并显示相同的消息。

yum info python ==> 安装包 python 2.7.5 34.el7

yum info python-devel ==> 未安装。可用 2.7.5 48.el7

yum deplist python-devel ==> 依赖于 python2.7.5-48.el7

尝试使用“yum update python”安装 Python2.7.5-48.el7，但失败并显示与 python-devel 安装相同的错误消息。

Answer 1

从 yum 文档中，这是处理 5 个错误的最安全方法:

运行此命令后，首先删除重复项并解决任何错误:

package-cleanup --cleandupes

如果上面带有缺少包清理错误，那么首先运行它:

yum install yum-utils

然后解决其他 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。

对指示为丢失的其他 3 个包重复上述命令。如果 yum 命令给你错误，那么只对那个包试试这个:

rpm -ivh --force grep-*

然后最后从原始错误消息中重新运行 yum 命令。

在任何时候你想清理剩余的困惑，运行这个命令:

yum clean all
package-cleanup --problems

并遵循指示。如需进一步引用，请使用以下方式查找文档
