title: no "go to definition" and no function definition pop-up for golang code
body: <p>I am using visual studio code to code in golang.</p>
  <p>For this particular code example: <a href="https://golang.org/pkg/net/rpc/" rel="nofollow noreferrer">https://golang.org/pkg/net/rpc/</a>, I can't see any function definition pop-up, nor can I use &quot;go to definition&quot; in vscode by pressing F12. I can see the definition pop-up in other projects on my computer.</p>
  <p>I have set my gopath in .bashrc in ubuntu 16.04 using the env.sh</p>
  <p>All the plugin and visual studio code versions are the latest. What should I do to use the function definition prompt?</p>
  <p>update: the problem is now solved by setting:</p>
  <pre><code>export GOPATH=`pwd` 
  </code></pre>
  <p>instead of:</p>
  <pre><code>export GOPATH=${GOPATH}:`pwd`
  </code></pre>
  <p>Thank you all!Though I still have no idea to have multiple gopath working.</p>
