• Perl 6 - CPAN

    Perl 学习交流QQ群，欢迎加入：909619846

    一、关于 CPAN

    CPAN（Comprehensive Perl Archive Network : 全面的Perl存档网络）

    CPAN 安装工具

    CPAN 安装工具有以下几种：

    • CPAN.pm ( cpan)是原始客户端。
      它随Perl一起提供，因此您已经拥有了它.它具有最多的功能.尽管实际上每个人都接受默认安装，但它具有许多配置选项以自定义其工作方式.它可以轻松地与 local :: lib 集成.
    • cpanminus (cpanm) 尝试进行零配置自动为大多数用户执行正确操作的客户端。
      它还可以在资源有限的系统(例如 VPS )上很好地运行.
      它不随Perl一起提供，但易于安装.它可以与 local :: lib 轻松集成.
      它的最大局限性是缺乏配置.如果您想做一些不寻常的事情，它可能不支持.
    • CPANPLUS (cpanp)是一种尝试使Perl程序可以使用的CPAN API使用，而不是您在命令行中使用的应用。
      cpanp shell更像是一种概念证明，我不知道使用它的任何真正优势.

    其中 CPANM 是目前最常用的一种

    二、metacpan

    https://metacpan.org

    使用示例

    这里我们搜索 restful，第一个得到 Mojolicious::Plugin::RESTful - A Mojolicious Plugin for RESTful HTTP Actions
    https://metacpan.org/pod/Mojolicious::Plugin::RESTful

    点击左边 Tools – Install Instructions
    在这里插入图片描述

    我们可以得到两种安装方式： cpanm 和 cpan，下面具体介绍下这两个安装工具的使用

    三、使用 CPAN

    Mac 预装了 cpan，终端输入 cpan，第一次会提示你一些配置信息

    第一次使用

    $ cpan
Loading internal logger. Log::Log4perl recommended for better logging CPAN.pm requires configuration, but most of it can be done automatically.

If you answer 'no' below, you will enter an interactive dialog for each
configuration option instead.

Would you like to configure as much as possible automatically? [yes] yes

Use of uninitialized value $what in concatenation (.) or string at /System/Library/Perl/5.30/App/Cpan.pm line 679, <STDIN> line 1.
 <install_help>

Warning: You do not have write permission for Perl library directories.

To install modules, you need to configure a local Perl library directory or escalate your privileges.  
CPAN can help you by bootstrapping the local::lib module or by configuring itself to use 'sudo' (if available).  
You may also resolve this problem manually if you need to customize your setup.

What approach do you want?  (Choose 'local::lib', 'sudo' or 'manual')
 [local::lib] 


Autoconfiguration complete.

local::lib is installed. You must now add the following environment variables
to your shell configuration files (or registry, if you are on Windows) and
then restart your command line shell and CPAN before installing modules:

PATH="/Users/xx/perl5/bin${PATH:+:${PATH}}"; export PATH;
PERL5LIB="/Users/xx/perl5/lib/perl5${PERL5LIB:+:${PERL5LIB}}"; export PERL5LIB;
PERL_LOCAL_LIB_ROOT="/Users/xx/perl5${PERL_LOCAL_LIB_ROOT:+:${PERL_LOCAL_LIB_ROOT}}"; export PERL_LOCAL_LIB_ROOT;
PERL_MB_OPT="--install_base \"/Users/xx/perl5\""; export PERL_MB_OPT;
PERL_MM_OPT="INSTALL_BASE=/Users/xx/perl5"; export PERL_MM_OPT;

commit: wrote '/Users/xx/.cpan/CPAN/MyConfig.pm'

You can re-run configuration any time with 'o conf init' in the CPAN shell
Terminal does not support AddHistory.

To fix enter>  install Term::ReadLine::Perl


cpan shell -- CPAN exploration and modules installation (v2.22)
Enter 'h' for help.

    使用 cpan 安装第三方库

    安装包位于目录： ~/.cpan/build
    相关配置文件为：~/.cpan/FTPstats.yml

    方式一：进入交互模式，安装

    $ cpan 
# $ perl -MCPAN -e shell  效果同上
...
cpan[1]> install Switch   
cpan[2]> exit # 退出交互模式

    方式二：直接使用 cpan install 安装

    $ cpan install Switch

$ cpan install XML::LibXML

    • 1
    • 2
    • 3

    检查模块是否已安装

    perl -e 'use XML::LibXML'

    不报错即代表安装成功

    查看模块信息

     $ cpan -i Switch

    四、使用 CPANM

    mac 上使用 brew 安装 CPANM

    $ brew install cpanminus

    • 1

    安装成功校验

    查看版本信息

    $ cpanm  -V
cpanm (App::cpanminus) version 1.9018 (/usr/local/bin/cpanm)

  cpanm --interactive Task::Kensho                          # Configure interactively
  cpanm .                                                   # install from local directory
  cpanm --installdeps .                                     # install all the deps for the current directory
  cpanm -L extlib Plack                                     # install Plack and all non-core deps into extlib
  cpanm --mirror http://cpan.cpantesters.org/ DBI           # use the fast-syncing mirror
  cpanm -M https://cpan.metacpan.org App::perlbrew          # use only this secure mirror and its index

You can also specify the default options in PERL_CPANM_OPT environment variable in the shell rc:

  export PERL_CPANM_OPT="--prompt --reinstall -l ~/perl --mirror http://cpan.cpantesters.org"

Type `man cpanm` or `perldoc cpanm` for the more detailed explanation of the options.
