1. 查看全部配置

cpan[1]> o conf
    commit             [Commit changes to disk]
    defaults           [Reload defaults from disk]
    help               [Short help about 'o conf' usage]
    init               [Interactive setting of all options]
    ...
    commandnumber_in_prompt [1]
    commands_quote     undef
    connect_to_internet_ok [1]
    cpan_home          [~/.cpan]
    curl               [/anaconda3/bin/curl]
    dontload_hash      undef
    dontload_list      undef
    lynx               [/usr/bin/lynx]
    make               [/anaconda3/envs/R-3.6.1/bin/make]
    make_arg           []
    make_install_arg   []
    make_install_make_command [/anaconda3/envs/R-3.6.1/bin/make]
    makepl_arg         [INSTALLDIRS=site]
    ...
    trust_test_report_history [0]
    unzip              [/usr/bin/unzip]
    urllist           
    use_sqlite         [0]

2. 查看指定配置

如，查看 make 的路径

cpan[2]> o conf make

查看源

cpan[3]> o conf urllist

3. 修改指定配置

cpan[4]> o conf make new_make_path

4. 增加源

添加一个

cpan[5]> o conf urllist push http://mirrors.aliyun.com/CPAN/

一次增加多个源

cpan[6]>  o conf urllist ftp://mirrors.sohu.com/CPAN/ http://mirrors.163.com/cpan/

5. 删除源

移除一个源

cpan[7]> o conf urllist pop http://mirrors.163.com/cpan/ ftp://mirrors.sohu.com/CPAN/

6. 提交修改

cpan[8]> o conf commit

7. 重新初始化

如果对当前的 cpan 配置不满意，可以重新初始化配置

cpan[9]> o conf init
