以brew安装go为例。

<pre class="prettyprint"><code class=" hljs bash"><span class="hljs-keyword">export</span> PATH=<span class="hljs-variable">$PATH</span>:/usr/local/opt/go/libexec/bin <span class="hljs-keyword">export</span> GOROOT=/usr/local/opt/go/libexec <span class="hljs-keyword">export</span> GOPATH=<span class="hljs-variable">$HOME</span>/.go <span class="hljs-keyword">export</span> PATH=<span class="hljs-variable">$PATH</span>:<span class="hljs-variable">$GOROOT</span>/bin:<span class="hljs-variable">$GOPATH</span>/bin</code></pre>

前以上加入.zshrc，source ~/.zshrc使之生效
注：export PATH=$PATH:/usr/local/opt/go/libexec/bin不设置也是可以的，因为/usr/local/bin中有对应的链接。
