Where does go get $GOPATH from?

<p>I&#39;m trying to install some software and get the following error:</p> <pre><code>maruwan@ubuntu:~$ go get github.com/gorilla/rpc/v2/json2 package github.com/gorilla/rpc/v2/json2: cannot download, $GOPATH not set. For more details see: go help gopath maruwan@ubuntu:~$ echo $GOPATH /home/maruwan/go maruwan@ubuntu:~$ </code></pre> <p>Both my .profile and .bashrc contain these lines:</p> <pre><code>GOPATH=&#34;$HOME/go&#34; # contains bin, src &amp; pkg GOROOT=&#34;$HOME/Stuff/go&#34; # contains go source </code></pre> <p>Can anyone help me debug this?</p> <hr/>**评论：**<br/><br/>maruwan: <pre><p>I figured it out: I neded <code>export GOPATH=...</code></p> <p>I added the <code>export</code> and now it works.</p></pre>jerf: <pre><p>Yes. In one of shell&#39;s many annoyances, there are local variables and exported variables, and virtually no indication which you have when you look.</p></pre>Femaref: <pre><p><code>env</code> access global, <code>set</code> shell variables.</p></pre>
