我花了几个小时，但无法安装 CPAN Crypt::OpenSSL::RSA 模块。它是 Postfix 的 dkimproxy 附加组件所必需的。
我所做的是在 shell 中运行以下命令：
$ perl -MCPAN -e 'install Crypt::OpenSSL::RSA'
当我运行此命令时，会显示几行，最后显示以下内容：
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]
然后我按下回车键（是），结果出现了几十行错误。最后我得到了这个：
...

我做错了什么？请指导我。谢谢。
答案1
我自己在 CentOS 5.4 上遇到了这个问题，我没有安装 openssl-devel！因此运行：
yum install openssl-devel
帮我修好了
或者如果你使用的是基于 Debian 的系统：
sudo apt-get install libssl-dev
答案2
奇怪的是，我在 Debian Squeeze 上安装了类似的软件，但这个模块总是失败。
perl Makefile.PL
警告：未找到先决条件 Crypt::OpenSSL::Random 0。为 Crypt::OpenSSL::RSA 编写 Makefile
..但我找不到您提到的确切软件包。ii libcrypt-openssl-bignum-perl 0.04-2 访问 OpenSSL 多精度整数运算库 ii libcrypt-openssl-dsa-perl 0.13-4 实现 DSA 签名验证系统的模块 ii libcrypt-openssl-rsa-perl 0.25-1+b1 提供基本 RSA 功能的 Perl 模块 ii libcrypt-openssl-x509-perl 1.4-1 OpenSSL X509 API 的 Perl 扩展
答案3
你在某个地方缺少一个头文件。在输出中你发布的内容上方，你应该看到对缺少的 .h 文件的引用。找出哪个包提供了该特定头文件，你就离成功更近了一步。反复操作...冲洗...重复，最终它会编译的 :)
答案4
是的，这也解决了我在 Debian 机器上遇到的问题。
运行 Aptitude，然后搜索“openssl”并看到 lib-openssl 包，并安装它。
重新运行 CPAN，安装 Crypt::OpenSSL::RSA 并且一切顺利。
