Centos：yum install libevent-devel 与 compat-libevent 冲突

我想安装 Logstash 和其他程序，但是当我尝试时：

# yum install libevent-devel

我收到以下错误：

Transaction Check Error:

Summary     : Abstract asynchronous event notification library
Description :
The libevent API provides a mechanism to execute a callback function
when a specific event occurs on a file descriptor or after a timeout
has been reached. libevent is meant to replace the asynchronous event
loop found in event driven network servers. An application just needs
to call event_dispatch() and can then add or remove events dynamically
without having to change the event loop.

答案1

您现有的版本compat-libevent14来自PostgreSQL yum 存储库。有一个漏洞打开compat-libevent14关于和之间的冲突libevent-devel。和另一个。

假设您需要启用 PostgreSQL 存储库，最好的做法是从 PostgreSQL 存储库中删除compat-libevent14并安装libevent和libevent-devel。这将需要删除任何需要 的软件包compat-libevent14，因此只有您才能决定这是否是合理的做法。

如果这不起作用，您的选择通常是（a）联系 PostgreSQL yum 存储库的维护人员，看看他们是否有计划解决这些错误或（b）自己解决问题并推出您自己的软件包。

答案2

如果您不需要compat-libevent14PostgreSQL repo 中提供的 libevent 版本，或者不需要该版本，则可以在 PostgreSQL repo 文件中添加排除指令。

您/etc/yum.repos.d/pgdg-93-centos.repo可以编辑该[pgdg93]部分并添加以下行：

exclude=*libevent*

确保将其添加到 repo 文件中的正确部分。这将从 PostgreSQL repo 中排除任何 libevent 包，并且您的包安装不会发生包冲突。
