我如何告诉CPAN.pm在哪里获取模块？

以下是CPAN的完整安装命令和输出:

sudo perl -MCPAN -e "install Bundle::CPAN"
CPAN: Storable loaded ok (v2.13)
Going to read /home/delgreco/.cpan/Metadata
  Database was generated on Mon, 08 Dec 2008 03:27:10 GMT
CPAN: LWP::UserAgent loaded ok (v2.033)
CPAN: Time::HiRes loaded ok (v1.55)
CPAN: YAML loaded ok (v0.39)
Warning: YAML version '0.39' is too low, please upgrade!
I'll continue but problems are *very* likely to happen.
Your urllist is empty! The urllist can be edited. E.g. with 'o conf urllist
push ftp://myurl/'

这对我有用,谢谢......

cpan> o conf urllist http://cpan.yahoo.com/

当然,Bundle :: CPAN安装在其他依赖项上继续失败,但至少我现在有一个YAML 0.68.

这看起来很重要:

Your urllist is empty! The urllist can be edited. E.g. with 'o conf urllist push ftp://myurl/'

也许跑sudo cpan,然后o conf init或o conf urllist push http://cpan.yahoo.com/(例如)让你urllist理顺？然后尝试进行安装.
