1)配置文件： /usr/lib/perl5/5.8.8/CPAN/Config.pm
如果第一次運行cpan命令
cpan提示進行交互的進行配置
當然我們根據自己的需要也可以手動的編輯此文件
貼一下自己的配置：
# 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.
$CPAN::Config = {
'build_cache' => q[10],
'build_dir' => q[/root/.cpan/build],
'cache_metadata' => q[1],
'cpan_home' => q[/root/.cpan],
'dontload_hash' => { },
'ftp' => q[/usr/kerberos/bin/ftp],
'ftp_proxy' => q[],
'getcwd' => q[cwd],
'gpg' => q[/usr/bin/gpg],
'gzip' => q[/usr/bin/gzip],
'histfile' => q[/root/.cpan/histfile],
'histsize' => q[100],
'http_proxy' => q[],
'inactivity_timeout' => q[0],
'index_expire' => q[1],
'inhibit_startup_message' => q[0],
'keep_source_where' => q[/root/.cpan/sources],
'links' => q[/usr/bin/links],
'make' => q[/usr/bin/make],
'make_arg' => q[],
'make_install_arg' => q[],
'makepl_arg' => q[],
'ncftp' => q[],
'ncftpget' => q[],
'no_proxy' => q[],
'pager' => q[/usr/bin/less],
'prerequisites_policy' => q[ask],
'scan_cache' => q[atstart],
'shell' => q[/bin/bash],
'tar' => q[/bin/tar],
'term_is_latin' => q[1],
'unzip' => q[/usr/bin/unzip],
'urllist' => [q[http://cpan.modperl.cn/]],
'wget' => q[/usr/bin/wget],
};
1;
__END__
2)如果需要重新配置CPAN,輸入：
#cpan
進入cpan後，輸入：
#CPAN>o conf init
重新配置後Config.pm如下：
$CPAN::Config = {
'applypatch' => q[],
'auto_commit' => q[0],
'build_cache' => q[10],
'build_dir' => q[/root/.cpan/build],
'build_dir_reuse' => q[1],
'build_requires_install_policy' => q[ask/yes],
'bzip2' => q[/usr/bin/bzip2],
'cache_metadata' => q[1],
'check_sigs' => q[0],
'colorize_output' => q[0],
'commandnumber_in_prompt' => q[1],
'cpan_home' => q[/root/.cpan],
'curl' => q[/usr/bin/curl],
'dontload_hash' => { },
'ftp' => q[/usr/kerberos/bin/ftp],
'ftp_passive' => q[1],
'ftp_proxy' => q[],
'getcwd' => q[cwd],
'gpg' => q[/usr/bin/gpg],
'gzip' => q[/usr/bin/gzip],
'histfile' => q[/root/.cpan/histfile],
'histsize' => q[100],
'http_proxy' => q[],
'inactivity_timeout' => q[0],
'index_expire' => q[1],
'inhibit_startup_message' => q[0],
'keep_source_where' => q[/root/.cpan/sources],
'load_module_verbosity' => q[v],
'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[],
'ncftp' => q[],
'ncftpget' => q[],
'no_proxy' => q[],
'pager' => q[/usr/bin/less],
'patch' => q[/usr/bin/patch],
'prefer_installer' => q[MB],
'prefs_dir' => q[/root/.cpan/prefs],
'prerequisites_policy' => q[ask],
'scan_cache' => q[atstart],
'shell' => q[/bin/bash],
'show_unparsable_versions' => q[0],
'show_upload_date' => q[0],
'show_zero_versions' => q[0],
'tar' => q[/bin/tar],
'tar_verbosity' => q[v],
'term_is_latin' => q[1],
'term_ornaments' => q[1],
'test_report' => q[0],
'unzip' => q[/usr/bin/unzip],
'urllist' => [q[http://cpan.modperl.cn/]],
'use_sqlite' => q[0],
'wget' => q[/usr/bin/wget],
'yaml_load_code' => q[0],
'yaml_module' => q[YAML],
};
1;
__END__
3)安裝perl組件出錯：
/usr/bin/make — NOT OK
Running make test
Can’t test without successful make
Running make install
make had returned bad status, install seems impossible
一.可以嘗試
#cpan
cpan>o conf make /usr/bin/make
cpan>o conf commit
cpan>exit
然後用perl命令再安裝一下該組件，看能否成功。
二.原因也可能是默認緩存/root/.cpan中的數據損壞rm -rf ~/.cpan刪除後在perl -MCPAN -e shell中執行reload index然後執行install Bundle::CPAN最後執行reload CPAN即可正常通過命令行install MODULES
