perl - Net::SSLeay 不会安装

Question

cpan Net::SSLeay

Running install for module 'Net::SSLeay'
Running make for M/MI/MIKEM/Net-SSLeay-1.55.tar.gz
  Has already been unwrapped into directory /root/.cpan/build/Net-SSLeay-1.55-v9rgJp
Could not make: Unknown error
Running make test
  Can't test without successful make
Running make install
  Make had returned bad status, install seems impossible

我已经安装了这篇文章的所有库:
install perl module Net::SSLeay through cpan

我还尝试手动安装它，在 make 命令期间我有这个日志:

一些 CPAN 模块需要 C 头文件才能成功编译。它们以 -dev 结尾.这些通常不与操作系统打包在一起。对于 Net::SSLeay您需要安装 libssl-dev .

对于 Debian 发行版:sudo apt-get install libssl-dev
