[Update: as of Go 1.8, <code>GOPATH</code> defaults to <code>$HOME/go</code>, but you may still find this useful if you want to understand the <code>GOPATH</code> layout, customize it, etc.]

The official Go site <a href="http://golang.org/doc/code.html" rel="noreferrer">discusses GOPATH and how to lay out a workspace directory</a>.

<code>export GOPATH="$HOME/your-workspace-dir/"</code> -- run it in your shell, then add it to <code>~/.bashrc</code> or equivalent so it will be set for you in the future. Go will install packages under <code>src/</code>, <code>bin/</code>, and <code>pkg/</code>, subdirectories there. You'll want to put your own packages somewhere under <code>$GOPATH/src</code>, like <code>$GOPATH/src/github.com/myusername/</code> if you want to publish to GitHub. You'll also probably want <code>export PATH=$PATH:$GOPATH/bin</code> in your <code>.bashrc</code> so you can run compiled programs under <code>$GOPATH</code>. 

Optionally, <a href="https://twitter.com/rob_pike/status/467367507305574400" rel="noreferrer">via Rob Pike</a>, you can also set <code>CDPATH</code> so it's faster to <code>cd</code> to package dirs in bash: <code>export CDPATH=.:$GOPATH/src/github.com:$GOPATH/src/golang.org/x</code> means you can just type <code>cd net/html</code> instead of <code>cd $GOPATH/src/golang.org/x/net/html</code>. 

Keith Rarick <a href="https://twitter.com/krarick/status/467035722436718593" rel="noreferrer">notes</a> you can set <code>GOPATH=$HOME</code> to put Go's <code>src/</code>, <code>pkg/</code> and <code>bin/</code> directories right under your homedir. That can be nice (for instance, you might already have <code>$HOME/bin</code> in your path) but of course some folks use multiple workspaces, etc.

blocks|key|4687432|text|做export+GOPATH="/whatever/you/like/your/GOPATH/to/be"就行了。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4687433|entityMap^0|1|1G|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

Just do <code>export GOPATH="/whatever/you/like/your/GOPATH/to/be"</code>.

blocks|key|4687444|text|如果您在设置$GOPATH后遇到此问题，可能是因为您正在使用不受支持的shell运行它。我使用的是fish，但它不起作用，用bash启动它工作得很好。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4687445|entityMap^0|6|7|1D|4|1Q|4|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|O|8|@]|D|@]|E|$]]]|G|$]]

If you run into this problem after having <code>$GOPATH</code> set up, it may be because you're running it with an unsupported shell. I was using <code>fish</code> and it did not work, launching it with <code>bash</code> worked fine.

I had to run an application as root (to open a webserver on port 80), this produced the error for me, because the sudo user has a different environment than the normal user, hence GOPATH was not set.

If someone else is having this problem, add <code>-E</code> to the command, this will preserve the user environment.

<code>sudo -E go run main.go</code>

blocks|key|4687489|text|对于MAC来说，这对我来说很有效。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4687490|sudo+nano+/etc/bashrc|code-block|syntax|javascript|4687491|并在文件末尾添加以下内容|4687492|export+PATH=$PATH:/usr/local/opt/go/libexec/bin

For MAC this worked well for me. 

<pre><code>sudo nano /etc/bashrc
</code></pre>

and add the below at the end of the file

<pre><code>export PATH=$PATH:/usr/local/opt/go/libexec/bin
export GOPATH=/usr/local/opt/go/bin
</code></pre>

This should fix the problem. Try opening a new terminal and echo $GOPATH you should see the correct value.

Your <code>$GOROOT</code> should not be set up.

I am using vim to edit my .bashrc file but you code use a gui editor such as <code>gedit</code>.
Steps:
Kindly subsitute <code>/path/to/golang/projects</code> below with your actual path location where you will store your golang projects.
Open .bashrc file in vim that is <code>vim ~/.bashrc</code>. Then add below lines at the end of the file.
<pre><code># Setup Golang Development Environment ::
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
 
# Third party go libraries will live under &quot;~/golib&quot; directory
export GOPATH=&quot;$HOME/golib&quot;
export PATH=&quot;$PATH:$GOPATH/bin&quot;
 
# Where your golang project code lives
export GOPATH=$GOPATH:/path/to/golang/projects
</code></pre>
Save the file and type <code>source ~/.bashrc</code> to refresh your terminal session.
Now try getting a package e.g. <code>go get github.com/pilu/fresh</code> and check your <code>~/golib/bin</code> directory it should have <code>fresh</code> package in it.
Navigate to your <code>/path/to/golang/projects</code> and create three folders in there i.e. <code>bin</code>,<code>src</code> and <code>pkg</code>
Now place your project folder inside <code>/path/to/golang/projects/src</code> e.g. <code>/path/to/golang/projects/src/myfancygolangproject</code>and you should be good to go. Put all your golang codebase in there mate.
