在我的Centos 6服务器上，我使用city-fan.repo更新了curl但安装后我遇到了问题...我发现（搜索时间之后）它是由于libssh2旧版本所以我删除了它并再次下载重新编译它，但编译它没有安装GCC，当我尝试./configure libssh2-1.6.1-20150617我有这个错误：
configure: error: no acceptable C compiler found in $PATH
，所以我从Centos repo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

当我尝试安装时，我得到了这个：
rpm -ivh *.rpm

如果我运行任何yum命令，它会显示我的错误：
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:

我对此非常新手......有什么帮助吗？感谢

你已经主要用了你的系统。
您下载的rpm软件包比您已安装的软件包早（这是该错误消息告诉您的内容）。
获取你删除的libssh2和curl包的rpm包并修复yum。
然后找到一个更好的方法来做你想做的事情。任何需要您以官方软件包无法处理的方式升级操作系统核心组件（如libcurl）的东西都会被设计破坏。

您是否尝试过以下操作：
yum provides libssh2.so.1
然后安装一个提供包
e.g。 yum install libssh2？
