title: Error Please install pg package manually with AWS Lambda serverless framework
body: <p>recently i had a big headache deploying my serveless application.</p>
  <p>I have a lambda function that connect to a Postgresql database. To deploy my application i use serverless framework.</p>
  <p>So, after doing my code when testing my code i got the follow error:</p>
  <p><strong>Please install pg package manually</strong></p>
  <p>But, i have installed pg on my package.json.</p>
  <p>All the same the error still happened.</p>
  <p>So, why do i have this error if the pg is installed correctly?</p>
