title: Can't import a local sub directory
body: <p>I have the main file &quot;main.go&quot; in the root of my project and there's also a subdirectory named &quot;models&quot; wherein there're multiple *.go files as well.
  In the main.go there's this:</p>
  <pre><code>import &quot;./models&quot;
  </code></pre>
  <p>When I build the project</p>
  <pre><code>go build
  </code></pre>
  <p>this error appears:</p>
  <pre><code>main.go:16:2: package models is not in GOROOT (/usr/lib/go/src/models)
  </code></pre>
  <p>How to fix this?</p>
  <p>Also, what if I created subdirectories inside &quot;models&quot; as well, how and from where would I have to import them? Later on I'll need this.</p>
