在编译装置FS环境的时分发现怎么报错：
yum编译履行指令如下：
yum install ntpdate wget autoconf automakelibtool gcc-c++ zlib-devel libjpeg-devel sqlite-devel libcurl-devel pcre-develspeex-devel libedit-devel openssl-devel libogg-devel libvorbis-devel
报错信息如下：
Error Downloading Packages:

处理思路：
1：履行yum clean all 铲除缓存目录下的软件包及旧的headers;
2：接着履行 yum list 从头列出一切现已装置和能够装置的软件包;
3：从头履行上述指令，发现yum编译成功;
留意：假如履行 yum list 报错，那就检查一下yum库房是否有问题;并铲除/etc/yum.repos.d/下剩余.repo文件!
