Question

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。我收到了错误

我是否需要先做其他事情？

Answer 1

最简单的解决方案，因为你从macports使用perl，也可以从macports安装DateTime：

sudo port install p5-datetime

Answer 2

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

Answer 3

您最好检查防火墙配置。 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/

为什么MacPorts的CPAN客户端无法找到Module :: Build？
