Centos Yum在更新libcurl时出错

在我的Centos 6服务器上，我使用city-fan.repo更新了curl，但在安装之后，我对yum有问题。。。我发现（在搜索小时后）这是由于旧版本的libssh2造成的，所以我删除了它并再次下载以重新编译它，但要编译它，没有安装GCC。当我尝试配置libssh2-1.6.1-20150617时，我出现以下错误：

configure: error: no acceptable C compiler found in $PATH

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

，因此我从Centos repo下载了这些软件包，因为我无法使用yum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，我得到以下信息：

 rpm -ivh *.rpm

如果我运行任何yum命令，它会显示以下错误：

configure: error: no acceptable C compiler found in $PATH

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

It's possible that the above module doesn't match the
current version of Python, which is:

我对这个很不熟悉…有什么帮助吗？谢谢

您已对系统进行了主要冲洗

您下载的rpm软件包比您已经安装的旧（这就是错误消息告诉您的）

获取已删除的libssh2和curl包的rpm包并修复它们

---

然后找到一个更好的方法去做你一开始想做的事情。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）的操作都会被设计破坏。

您是否尝试过以下操作：

yum provides libssh2.so.1

然后安装其中一个提供的软件包

e、 g.

yum安装libssh2
