puppet 重複引用類報錯

在 node default ｛｝ 中引用了一個類，而後又在node.pp 中又引用了一次，結果報錯：

 Info: Retrieving plugin Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not parse for environment production: No file(s) found for import of 'cron' at /etc/puppet/manifests/modules.pp:2 on node test.com Warning: Not using cache on failed catalog Error: Could not retrieve catalog; skipping run
