If you set a variable like this:

<pre><code>GOPATH=$HOME/go
</code></pre>

It won't be exported to any subprocesses. It's only available to that process. If you want to export it to subprocesses, use <code>export</code>:

<pre><code>export GOPATH
</code></pre>

You can also combine the assignment and export:

<pre><code>export GOPATH=$HOME/go
</code></pre>

blocks|key|702661|text|我的$GOROOT目录是用owner:+root和group:+wheel创建的，它的所有者是我，管理员是组。我会猜我使用sudo时，我不应该这么做(或者某个工具为我做的)。因此，go+get无法将包写入$GOROOT，从而导致$GOPATH+not+set和permission+denied错误。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|702662|通过在我的chown和chgrp上使用$GOROOT+(使用-R获取子文件夹)+'go+get+.‘起作用了。在我的例子中，VS+Code现在能够安装我所追求的Go组件。|702663|entityMap^0|D|B|P|C|2I|6|36|F|3M|H|0|5|5|B|5|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]|$9|S|A|T|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|U|8|@$9|V|A|W|B|C]|$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|Z|8|@]|D|@]|E|$]]]|I|$]]

My $GOROOT directory was created with <code>owner: root</code> and <code>group: wheel</code> instead having me as the owner and admin as the group. I'll guess that I used sudo when I shouldn't have (or some tool did it for me). As such <code>go get</code> could not write the packages to $GOROOT and hence the <code>$GOPATH not set</code> and <code>permission denied</code> errors.

By using <code>chown</code> and <code>chgrp</code> on my $GOROOT (with -R to get subfolders) 'go get...' worked. In my case VS Code was now able to install the Go components I was after.

blocks|key|3323081|text|当您运行go+env时，您应该能够查看您的GOPATH是否已设置。不过，在我的情况下，当我在终端上运行它时，这个命令就会解决这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3323082|export+GOPATH=/usr/local/bin|code-block|syntax|javascript|3323083|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

When you run go env, you should be able to see if your GOPATH has been set.
On my case though, this command solves it when I had it run on my terminal.

<pre><code>export GOPATH=/usr/local/bin
</code></pre>

blocks|key|702720|text|我已经设置了GOPATH，它用命令go+env正确显示。我必须使用chmod向go目录授予正确的权限，并通过go+get+github.com/constabulary/gb/...安装gb。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|702721|entityMap^0|6|6|H|6|X|5|1I|11|2L|2|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]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|G|$]]

i had setup <code>GOPATH</code> and it showed correctly with command <code>go env</code>. i had to give the correct permissions to the go directory using <code>chmod</code> and install <code>gb</code> by <code>go get github.com/constabulary/gb/...</code>.

blocks|key|4158548|text|首先做一个‘去env’，并检查路径GOROOT。因此，设置GOPATH。在我的例子中，它必须将GOPATH设置为/usr/lib/go。早些时候，我尝试过/usr/share/go和/usr/bin/go，但是它没有工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4158549|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

First do a `go env' and check the path GOROOT. Accordingly set the GOPATH.
In my case, it had to set GOPATH to /usr/lib/go. Earlier i tried it with /usr/share/go and /usr/bin/go but it didn't work.

blocks|key|4158559|text|$GOPATH应该是您的当前工作区，项目所在的文件夹。或者只需cd+~/go并尝试运行这些命令。或者只需更新ubuntu上的~/..bashrc或~/..bashrc_profile中的$GOPATH即可。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4158560|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

$GOPATH should be your current workspace , a folder where your project resides.
or just cd ~/go and try to run those commands.
Or you can just update $GOPATH in ~/.bashrc or ~/.bashrc_profile on ubuntu

Setup:

Have a look at my configuration:

<pre><code>$ echo $GOPATH &amp;&amp; ls -r $GOPATH
/home/cyrus/.go
src pkg bin

$ echo $GOROOT &amp;&amp; ls $GOROOT
/usr/local/go
api AUTHORS bin CONTRIBUTORS doc favicon.ico include lib LICENSE misc PATENTS pkg README robots.txt src test VERSION
</code></pre>

You can see that I've set a path for <code>$GOPATH</code>. In addition, I've created subdirectories that I may not need.

Question:

Why does the following command generate this error message?

<pre><code>$ go get code.google.com/p/go-tour/gotour 
package code.google.com/p/go-tour/gotour: cannot download, $GOPATH not set. For more details see: go help gopath
</code></pre>

Error "cannot download, $GOPATH not set."
