在我的 Centos 6 服务器上，我使用 city-fan.repo 更新了 curl，但在安装后我遇到了 yum 问题......我发现（搜索数小时后）这是由于libssh2旧版本，所以我删除了它并再次下载以重新编译它，但是编译它没有安装GCC，当我尝试./配置libssh2-1.6.1-20150617时，我有这个错误：
configure: error: no acceptable C compiler found in $PATH
，所以我从 Centos 存储库下载了这些软件包，因为我无法使用 yum 来安装 gcc：
cloog-ppl-0.15.7-1.2.el6.x86_64.rpm glibc-common-2.12-1.149.el6.x86_64.rpm kernel-headers-2.6.32-504.el6.x86_64.rpm
compat-libstdc++-33-3.2.3-69.el6.x86_64.rpm gcc-4.4.7-11.el6.x86_64.rpm glibc-devel-2.12-1.149.el6.x86_64.rpm mpfr-2.4.1-6.el6.x86_64.rpm
cpp-4.4.7-11.el6.x86_64.rpm glibc-2.12-1.149.el6.x86_64.rpm glibc-headers-2.12-1.149.el6.x86_64.rpm ppl-0.10.2-11.el6.x86_64.rpm
当我尝试安装这些时，我得到这个：
rpm -ivh *.rpm

如果我运行任何 yum 命令，它会向我显示此错误：
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
libssh2.so.1: cannot open shared object file: No such file or directory
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.6.6 (r266:84292, Jan 22 2014, 09:42:36)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
我对此非常陌生...有什么帮助吗？谢谢
你主要冲洗你的系统。
您下载的 rpm 软件包比您已经安装的软件包旧（这就是该错误消息告诉您的）。
获取您删除的 libssh2 和 curl 软件包的 rpm 软件包并修复 yum。
然后找到一种更好的方法来做你最初想做的任何事情。任何需要你以官方软件包无法处理的方式升级操作系统的核心组件（如libcurl）的东西都是设计破坏的。
您是否尝试过执行以下操作：
yum provides libssh2.so.1
然后安装其中一个提供包
例如 yum install libssh2 ？
