perl - 安装 Perl 日期时间

Question

在为 Perl 安装 DateTime 时，出现以下错误并且失败；

#   Failed test 'Make sure we can add 50 years worth of years in America/New_York time zone'
#   at t/30future-tz.t line 45.
Use of uninitialized value in numeric ge (>=) at /home/bensley/.cpan/build/DateTime-0.72/blib/lib/DateTime.pm line 138.

#   at t/30future-tz.t line 45.

完整的输出很长，所以我把它贴在这里: http://pastebin.com/raw.php?i=JiJeH4ij

我是 Perl 模块的新手，因此完全迷路了。这里发生了什么？

更新:

$ perl --version

This is perl, v5.8.8 built for i486-linux-gnu-thread-multi

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 8.04.4 LTS
Release:    8.04

这很可能是你的问题。

Package seems to come without Makefile.PL.
  (The test -f "/home/bensley/.cpan/build/DateTime-0.72/Makefile.PL" returned false.)
  Writing one on our own (setting NAME to DateTime)

您的 CPAN 客户端副本已经过时，无法识别"new"(我的意思是 10 岁) Build.PL模块构建和安装机制。相反，CPAN 编写了自己的安装程序并尝试进行安装。这适用于许多 Perl 模块，但它可能错过了 DateTime 所需的一些微妙之处。

升级CPAN客户端，你可以用CPAN客户端做，然后再试一次。
