英文:
Why can't "go get" find $GOPATH when "go env" shows it's set correctly?
问题
我正在尝试在我的Macbook Pro上安装go版本go1.6.4 darwin/amd64。
尽管已经设置了$GOPATH，但我似乎无法使用'go get'下载远程包。

你的$GOPATH设置在你的用户$PATH中，但是你正在使用sudo来调用go get，而sudo有自己独立的$PATH。
为了说明这一点，尝试运行sudo go env，你会看到它们之间的差异。
不过，你可能本来就不应该使用sudo go get。
英文:
Your $GOPATH is set in your user $PATH, but you are envoking go get using sudo which has its own $PATH different from yours.
To illustrate, try sudo go env and you will see the difference.
You probably shouldn't be using sudo go get anyway though.
