问题
从Go文档的外观来看，它们似乎在暗示你必须将你正在工作的代码放在$GOPATH下，这是正确的吗？
我想在我的~/Documents目录下设置一个测试项目的文件夹，但每次我运行go install example/newmath（就像在测试示例中一样），它都会显示以下内容：
λ MacBook-Air src → go install example/newmath
警告：设置的GOPATH为GOROOT（/usr/local/go）无效
无法加载包：包example/newmath：导入“example/newmath”：找不到包
这是否意味着我需要重置我的$GOPATH/$GOROOT？我迷失了。
英文:
From the looks of the go documentation, they make it seem like you have to put code you're working on under your $GOPATH-- is that correct?
I would like to set up a test project in a dir under my ~/Documents, but everytime i run go install example/newmath (like in the test example) it says the following--
λ MacBook-Air src → go install example/newmath
warning: GOPATH set to GOROOT (/usr/local/go) has no effect
can't load package: package example/newmath: import "example/newmath": cannot find package
Does that mean that i need to reset my $GOPATH/$GOROOT? I'm lost.

在一般情况下，不需要设置GOROOT。然而，GOPATH应该被设置（并且导出）。
我建议从以下命令开始：
export GOPATH=$HOME
然后将一个具有import "whatever"的包放入$GOPATH/src/whatever。
当你熟悉Go构建系统（go {build, install}）的工作方式后，你可以根据自己的需求来调整GOPATH。一个人甚至可以在$GOPATH中有多个项目，但我认为这在开始阶段并不重要，有时甚至永远不需要。
英文:
No need to setup GOROOT in the common situation. GOPATH, OTOH, should be set (and exported).
I would recommend to start with
export GOPATH=$HOME
Then just put a package having import "whatever" into $GOPATH/src/whatever.
You can refine your GOPATH to your needs later, when you get used to how things work with the Go build system (go {build, install}). One can have even multiple items in $GOPATH, but I really don't think it's a concern in the beginning, and sometimes never.
