CPAN模塊的遞歸依賴，如何？

Question

如何在perl中安裝所有依賴模塊Nmap :: Scanner？我做過，cpan Nmap :: Scanner。但是，需要模塊的其他依賴關係。

此代碼。

#!/bash/perl 

    use Nmap::Scanner; 
    my $scan = Nmap::Scanner->new(); 

    $scan->add_target('localhost'); 
    $scan->add_target('host.i.administer'); 
    $scan->add_scan_port('1-1024'); 
    $scan->add_scan_port('31337'); 
    $scan->tcp_syn_scan(); 
    $scan->noping(); 

    my $results = $scan->scan(); 

    my $hosts = $results->gethostlist(); 

    while (my $host = $hosts->get_next()) { 

     print "On " . $host->hostname() . ": \n"; 

     my $ports = $host->get_port_list(); 

     while (my $port = $ports->get_next()) { 
      print join(' ', 
       'Port', 
       $port->service() . '/' . $port->portid(), 
       'is in state', 
       $port->state(), 
       "\n" 
     ); 
     } 

    } 

我做了，但是在perl中運行腳本時，在控制檯中顯示了這一點。

cpan自動解決相關性。要安裝執行以下命令：

cpan Nmap::Scanner 

CPAN模塊的替代安裝程序是cpanminus。使用cpanm：

cpanm Nmap::Scanner
