我的目标是以编程方式自动配置 cpan。
如果您谈论的是具有已知配置的系统,只需创建(或修改)~/.cpan/CPAN/MyConfig.pm
. 例如,以下是我的:
$CPAN::Config = {
'auto_commit' => q[0],
'build_cache' => q[5],
'build_dir' => q[/home/ikegami/.cpan/build],
'build_requires_install_policy' => q[yes],
'cache_metadata' => q[1],
'check_sigs' => q[0],
'commandnumber_in_prompt' => q[1],
'connect_to_internet_ok' => q[1],
'cpan_home' => q[/home/ikegami/.cpan],
'dontload_hash' => { },
'ftp' => q[/usr/bin/ftp],
'ftp_passive' => q[1],
'ftp_proxy' => q[],
'getcwd' => q[cwd],
'gpg' => q[/usr/bin/gpg],
'gzip' => q[/bin/gzip],
'halt_on_failure' => q[0],
'histfile' => q[],
'http_proxy' => q[],
'inactivity_timeout' => q[0],
'index_expire' => q[1],
'inhibit_startup_message' => q[0],
'keep_source_where' => q[/home/ikegami/.cpan/sources],
'load_module_verbosity' => q[none],
'lynx' => q[],
'make' => q[/usr/bin/make],
'make_arg' => q[],
'make_install_arg' => q[],
'make_install_make_command' => q[/usr/bin/make],
'makepl_arg' => q[],
'mbuild_arg' => q[],
'mbuild_install_arg' => q[],
'mbuild_install_build_command' => q[./Build],
'mbuildpl_arg' => q[],
'ncftpget' => q[/usr/bin/ncftpget],
'no_proxy' => q[],
'pager' => q[less],
'perl5lib_verbosity' => q[none],
'prefer_external_tar' => q[1],
'prefer_installer' => q[MB],
'prerequisites_policy' => q[follow],
'scan_cache' => q[atstart],
'shell' => q[/bin/bash],
'show_upload_date' => q[0],
'tar' => q[/bin/tar],
'tar_verbosity' => q[none],
'term_is_latin' => q[1],
'term_ornaments' => q[1],
'trust_test_report_history' => q[0],
'unzip' => q[/usr/bin/unzip],
'urllist' => [q[http://ftp.osuosl.org/pub/CPAN/], q[http://mirrors.hub.co/CPAN/], q[http://cpan.arcticnetwork.ca/]],
'use_sqlite' => q[0],
'version_timeout' => q[15],
'wget' => q[/usr/bin/wget],
'yaml_load_code' => q[0],
};
1;
__END__
或者,您可以强制使用默认值,并修改需要更改的内容。例如,
cpan <<<'o conf init
yes
o conf prerequisites_policy ask
o conf commit
quit
'
o conf init
导致初始化过程开始。yes
接受默认值。o conf prerequisites_policy ask
是更改默认值的示例。o conf commit
保存更改。
