perl安装模块

1.cpan

   perl -MCPAN -e shell

   o conf init 可以初始化CPAN

   vi /usr/lib/perl5/5.8.8/CPAN/Config.pm 更改CPAN配置主要是镜像的配置

   163镜像  urllist' => [q[http://mirrors.163.com/cpan/]]

  install Net::Netmask

  就自动安装了

  m  /正则/  可以查看搜索模块

  2.perldoc perllocal查看安装了的模块 但是自带的模块不显示

     perldoc 模块  可以看到模块的使用方式

     查看函数使用方法
    perldoc -f map
    查看模块源代码
    perldoc -m CGI

3.perl的模块搜索路径

   #!/usr/bin/perl
#$\="\n";
$,="\n";
print @INC;
print "\n";

/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi
/usr/lib/perl5/site_perl/5.8.8
/usr/lib/perl5/site_perl
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi
/usr/lib/perl5/vendor_perl/5.8.8
/usr/lib/perl5/vendor_perl
/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi
/usr/lib/perl5/5.8.8
.

所以如果写好的模块放在当前目录下就能用

FILE/Find.pm

可以用 use FILE::Find来调用

Config.pm:




# This is CPAN.pm's systemwide configuration file. This file provides
# defaults for users, and the values can be changed in a per-user
# configuration file. The user-config file is being looked for as
# ~/.cpan/CPAN/MyConfig.pm.
