我所做的是在shell中运行以下命令：

$perl -MCPAN -e’安装Crypt :: OpenSSL :: RSA’

当我运行此命令时,显示几行,最后显示：

Checking if your kit is complete...
Looks good
Warning: prerequisite Crypt::OpenSSL::Random 0 not found.
Writing Makefile for Crypt::OpenSSL::RSA
---- Unsatisfied dependencies detected during [I/IR/IROBERTS/Crypt-OpenSSL-RSA-0.26.tar.gz] -----
    Crypt::OpenSSL::Random
Shall I follow them and prepend them to the queue
of modules we are processing right now? [yes]

然后我按Enter(是)和生成错误的数十行.最后我得到了这个：

...
...

我究竟做错了什么？请指导我.谢谢.
