title: Pages with `getServerSideProps` can not be exported
body: <p>I think i am making some kind of confusion here.</p>
  
  <p>According to the <a href="https://nextjs.org/docs/basic-features/pages#server-side-rendering" rel="noreferrer">documentation</a>, if i want Server Side Rendering (SSR) for the page i export the async function:</p>
  
  <pre><code>getServerSideProps
  </code></pre>
  
  <p>But if i do that i can't build the project for running either locally or now Zeit now.
  If i try build or deploy i get:</p>
  
  <blockquote>
    <p>Error for page /_error: pages with <code>getServerSideProps</code> can not be exported. See more info here: <a href="https://err.sh/next.js/gssp-export" rel="noreferrer">https://err.sh/next.js/gssp-export</a> </p>
  </blockquote>
  
  <p>The link provided by the error says i can't export. But I used the example from the documentation below:</p>
  
  <pre><code>import React from "react"
  
  export async function getServerSideProps() {
          return { props: {  } }
  }
  
  function Page({ data }) {
      // Render data...
  }
  
  export default Page
  </code></pre>
  
  <p>Do i have to change some configuration somewhere?</p>
  
  <p>How to prevent from building this static page? </p>
