安装 Perl Crypt::OpenSSL::RSA 模块时出错

Question

我花了几个小时但无法安装 CPAN Crypt::OpenSSL::RSA 模块。Postfix 的 dkimproxy 附加组件需要它。

我所做的是在shell中运行以下命令：

$ perl -MCPAN -e 'install Crypt::OpenSSL::RSA'

当我运行这个命令时，会显示几行，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] 

然后我按回车键（是），然后生成了几十行错误。最后我得到了这个：

我究竟做错了什么？请指导我。谢谢。

Answer 1

我自己刚刚在 CentOS 5.4 上遇到了这个问题，我没有安装 openssl-devel！所以运行：

yum install openssl-devel

为我修好了

或者，如果您使用的是基于 debian 的东西：

sudo apt-get install libssl-dev

您在某处缺少标头。在输出中发布的内容上方，您应该会看到对丢失的 .h 文件的引用。找出哪个包提供了该特定标头，您就更近了一步。起泡沫...冲洗...重复，最终它会编译:)
