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 #第一次选择 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] manual #第二次选择 Autoconfigured everything but 'urllist'. Now you need to choose your CPAN mirror sites. You can let me pick mirrors for you, you can select them from a list or you can enter them by hand. Would you like me to automatically choose some CPAN mirror sites for you? (This means connecting to the Internet) [yes] yes #第三次选择 Trying to fetch a mirror list from the Internet Fetching with HTTP::Tiny: http://www.perl.org/CPAN/MIRRORED.BY Looking for CPAN mirrors near you (please be patient) .. done! New urllist http://www.cpan.org/ Autoconfiguration complete. commit: wrote '/root/.cpan/CPAN/MyConfig.pm' You can re-run configuration any time with 'o conf init' in the CPAN shell Terminal does not support AddHistory. cpan shell -- CPAN exploration and modules installation (v1.9800) Enter 'h' for help.
