我在雪豹中使用macports。我想安装某些 perl 模块以便能够运行脚本。确切地说是 DateTime 模块。我该怎么做呢？我尝试使用以下命令。

perl -MCPAN -e shell
cpan > install DateTime

但它仍然说找不到 DateTime.pm。我做错了什么？

编辑：我认为我没有正确配置 CPAN。我得到了错误

  Adding it now as such.

我需要先做点别的吗？

最简单的解决方案，因为您使用的是 macports 中的 perl，所以也可以从 macports 安装 DateTime：

sudo port install p5-datetime

DateTime 使用 META.json - 尚不支持。所以先安装 Module::Build 。升级 CPAN 也是一个好主意。

你最好检查一下你的防火墙配置。CPAN 对服务器的访问可能会被阻止。无论如何，您可以下载并手动安装模块：http ://search.cpan.org/dist/DateTime/
