perl读取远程文件lwp安装

use LWP::UserAgent;
 $ua = LWP::UserAgent->new;
 $ua->agent("$0/0.1 " . $ua->agent);
 # $ua->agent("Mozilla/8.0") # pretend we are very capable browser
 
 $req = HTTP::Request->new(
    GET => 'http://www.baidu.com');
 $req->header('Accept' => 'text/html');
 
 # send request
 $res = $ua->request($req);
 print $res->decoded_content;

缺少网络连接库 LWP的时候报错
