title: Error "command not found" after installing go-eval
body: <p>I'm trying to run <code>Go</code> in an interactive mode.   </p>
  
  <p>I want to use <a href="https://github.com/sbinet/go-eval/" rel="noreferrer"><code>go-eval</code></a> for that, I followed their <code>README</code> instructions:</p>
  
  <ul>
  <li>I ran <code>go get github.com/sbinet/go-eval/</code> successfully</li>
  <li>I ran <code>go-eval</code> which resulted in <code>-bash: go-eval: command not found</code></li>
  </ul>
  
  <p>Some more information:</p>
  
  <ul>
  <li><p><code>echo $PATH</code> returns: <code>/usr/local/go/bin:...</code></p></li>
  <li><p><code>echo $GOPATH</code> returns: <code>$HOME/golang</code></p></li>
  <li><p>running <code>whereis go-eval</code> returns no output</p></li>
  <li><p>running <code>go install go-eval</code> returns:</p>
  
  <p><code>can't load package: package go-eval: cannot find package "go-eval" in any of:
    /usr/local/go/src/go-eval (from $GOROOT)
    $HOME/golang/src/go-eval (from $GOPATH)</code></p></li>
  </ul>
