Where is a good location for $GOPATH?
问题
我正在使用Go语言开发一个项目，需要使用一些外部库，比如MySQL驱动程序、图像处理库等等。目前，我将$GOPATH设置为/usr/lib/go/src，这会将下载的包放在/usr/lib/go/src/src目录下，显然这不正确。如果我将$GOPATH设置为/usr/lib/go，就会出现一个错误，提示不能将$GOPATH设置为与$GOROOT相同的目录。那么，我应该在我的build.sh中设置GOPATH=/path/to/my/project/lib，并在提交到git仓库时将lib/添加到.gitignore文件中吗？
我意识到这可能是一个愚蠢的问题。目前它运行得很好，我只是想知道这是否是一种不好的做法。
英文:
I'm working on a project in Go, which requires several external libraries, like a MySQL driver, an image manipulation library, etc. Right now, I have $GOPATH set to /usr/lib/go/src, which puts any downloaded packages in /usr/lib/go/src/src, which obviously doesn't seem right. If I set $GOPATH to /usr/lib/go, I get an error saying that $GOPATH can't be set to the same directory as $GOROOT. So should I put GOPATH=/path/to/my/project/lib in my build.sh, and when I commit to my git repo, put lib/ in my .gitignore?
I realize this is probably a silly question. It works fine as it is now, I'm just wondering if this is bad practice.

$GOPATH可以是您选择的任何位置（有一些例外），只要编译器知道在哪里找到它。如果您更改它，请确保使用以下命令更新路径：
export GOPATH=/path/to/gopath
我个人偏好将$GOPATH与我的代码分开，除非我正在编写一个通过go get <repo path>导入的包，这种情况下我会将代码写在：
$GOPATH/src/<repo path>
这是使用go get <repo path>时包存储的标准位置。
英文:
$GOPATH can really be any location you choose (with a few exceptions), so long as the compiler knows where to find it. If you change it just make sure you update the path with
export GOPATH=/path/to/gopath
My personal preference is to keep the $GOPATH separate from my code unless I'm writing a package which is meant to be imported via go get <repo path>, in which case I'll write the code in
$GOPATH/src/<repo path>
which is the standard location that the package gets stored when you use go get <repo path>
