centos虚拟机中装openssl解决报错问题

第一个报错提示从这个命令开始：
./config —pre fix=/usr/local
在这里插入图片描述

详细信息如下：
Ca n’t locate IPC/Cmd.pm in @INC (@INC contains: /home/smile/openssl–openssl-3.0.2/util/perl /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/v end o r _perl /us r/share/pe rl5/v e n do r _p e rl /us r/lib64/p e rl5 /us r/share/p erl5 . /home/smile/openssl–openssl-3.0.2/external/p erl/Text-Template-1.56/lib) at /home/smile/openssl–open ssl-3.0.2/util/p erl/OpenSSL/config.pm line 18.

显示缺失 IPC/Cmd.pm 这个文件，下一步安装这个，先使用了这个命令：
yum install –y perl-CPAN

好了，下一个报错信息如下：显示无可安装镜像信息
