title: unrecognized import path (import path does not begin with hostname)
body: <p>I've installed go as per the custom installation clause of <a href="https://golang.org/doc/install?download=go1.9.2.linux-amd64.tar.gz" rel="noreferrer">the installation instructions</a>, as I have installed to a user directory, in order to accommodate having multiple versions of go. </p>
  
  <p>When I <code>go get .</code> from my go project's src directory, I get the error message type already mentioned above ―</p>
  
  <blockquote>
    <p>unrecognized import path (import path does not begin with hostname)</p>
  </blockquote>
  
  <p>Can you please explain, why does go look for a hostname and how that should possibly be avoided in a typical project?</p>
  
  <p>As an aside, the problem was originally encountered by me in setting up the <a href="https://github.com/habeanf/yap/tree/9bd0606a7be454631bc8700fffe10a06c813963c" rel="noreferrer">following specific project and hash</a>, which the accepted answer still refers to.</p>
