NAME

Book::Chinese::MasterPerlToday::BeACPANTester - Be a CPAN Tester

DESCRIPTION

本章主要描述如何配置 CPAN 和成为一个 CPAN 测试者。

配置 CPAN

当你安装 Perl 完毕之后,在命令行状态下输入

    $ cpan

会出现类似如下的东西

    E:\Fayland\chinese-perl-book>cpan
    
    cpan shell -- CPAN exploration and modules installation (v1.94)
    ReadLine support enabled
    
    
    cpan>

这将表明您已经成功安装了 CPAN 模块。

  • 配置 CPAN

    在 cpan> 模式下输入

        cpan> o conf init

    将重新配置 CPAN 设置

        cpan> o conf urllist
        urllist
            0 [http://cpan.strawberryperl.com/]
            1 [http://www.cpan.org/]
    
        cpan> o conf urllist unshift http://cpan.perl.org/
        cpan> o conf urllist
        urllist
            0 [http://cpan.perl.org/]
            1 [http://cpan.strawberryperl.com/]
            2 [http://www.cpan.org/]

    可以快速控制模块远程网址。

  • 安装模块

        cpan> install Moose

    将开始安装或者升级模块。

  • 重载索引

        cpan> reload index

    cpan 默认缓存 index, 这样每次 install 模块的时候可以直接从索引文件构造出远程地址。有时候如果你发现你安装的模块不是最新版本时,可以使用 reload index 来强制更新索引。

  • 搜寻模块

        cpan> m /Catalyst.*?Trait/
        Module    Catalyst::TraitFor::Log::Audio (RJURNEY/Catalyst-TraitFor-Log-Audio-0.02.tar.gz)
        Module  = Catalyst::TraitFor::Model::DBIC::Schema::Caching (MSTROUT/Catalyst-Model-DBIC-Schema-0.26.tar.gz)
        Module  < Catalyst::TraitFor::Model::DBIC::Schema::QueryLog (FAYLAND/Catalyst-TraitFor-Model-DBIC-Schema-QueryLog-0.02.tar.gz)
        Module  = Catalyst::TraitFor::Model::DBIC::Schema::Replicated (MSTROUT/Catalyst-Model-DBIC-Schema-0.26.tar.gz)
        Module    Catalyst::TraitFor::Request::ProxyBase (VEEP/Catalyst-TraitFor-Request-ProxyBase-0.000003.tar.gz)
        Module  < CatalystX::Component::Traits (BOBTFISH/CatalystX-Component-Traits-0.08.tar.gz)
        6 items found

    更多搜索选项请使用帮助

        cpan> h
  • 安装老版本或测试版本模块

    有时候安装某个模块完毕之后可能发现出错,想安装回原来的模块。或者您的脚本只能运行在老版本的某个模块之上。或者你想测试某个新版本的模块。请尝试如下步骤

    首先打开该模块老版本的 CPAN 页面如 http://search.cpan.org/~mramberg/Catalyst-Runtime-5.7015/,然后查看 Download 的链接如 http://search.cpan.org/CPAN/authors/id/M/MR/MRAMBERG/Catalyst-Runtime-5.7015.tar.gz

        cpan> install MRAMBERG/Catalyst-Runtime-5.7015.tar.gz

    或者直接命令行下

        $> cpan MRAMBERG/Catalyst-Runtime-5.7015.tar.gz

    都会安装该版本模块而非最新的模块。

  • 安装某个本地或远程地址的包

    有时候某个包不在 CPAN 上,但是你想通过 cpan 简化安装的话,请安装 pip。安装之后:

        $> pip http://fayland.org/CPAN/Book-Chinese-MasterPerlToday-0.01.tar.gz
        # 或者
        $> pip Local-Package.tar.gz
  • 测试无法通过,但是我想强制安装

        cpan> force install Catalyst

    或者在命令行:

        $> perl -MCPAN -e 'force("install", "Foorum");'
  • 我想手工运行 perl Makefile.PL

        cpan> look DBIx::Class

在安装过程中您将可能遇到以下问题:

CPAN 测试者

成为一个 CPAN 测试者是对 Perl 社区最快速的贡献办法之一。

    cpan> install CPAN::Reporter
    cpan> reload cpan
    cpan> o conf init test_report

这就是成为一个 CPAN 测试者您所需要的所有动作。

minicpan

    cpan> install CPAN::Mini

CPAN::Mini 主要用于创建一个本地最小的 CPAN 镜像。它可以加速你的 CPAN 模块安装,或者可以让你在离线情况下安装 CPAN 模块。
