'go install' will not find package "fmt"
问题
我通过将go 1.7.4解压到~/go并相应地设置GOROOT来安装了它。我还创建了~/work/src/github.com/user/hello并相应地设置了GOPATH。
当我尝试从https://golang.org/doc/install#testing中的hello world示例时，我遇到了以下错误：
$ go install github.com/user/hello
../work/src/github.com/user/hello/hello.go:3:8: 找不到包"fmt"，它位于以下任何位置中：
/home/user/go/src/pkg/fmt（来自$GOROOT）
/home/user/work/src/fmt（来自$GOPATH）
package github.com/user/hello
导入runtime时出错：找不到包"runtime"，它位于以下任何位置中：
/home/user/go/src/pkg/runtime（来自$GOROOT）
/home/user/work/src/runtime（来自$GOPATH）
在检查~/go后，我发现fmt在~/go/src/fmt而不是~/go/src/pkg/fmt中。
感觉我漏掉了一些关键的东西。感谢您的帮助。
英文:
I installed go 1.7.4 by untarring it into ~/go and setting GOROOT accordingly. I also created ~/work/src/github.com/user/hello and set GOPATH accordingly.
When trying the hello world example from https://golang.org/doc/install#testing I get the following error:
$ go install github.com/user/hello
../work/src/github.com/user/hello/hello.go:3:8: cannot find package "fmt" in any of:
/home/user/go/src/pkg/fmt (from $GOROOT)
/home/user/work/src/fmt (from $GOPATH)
package github.com/user/hello
imports runtime: cannot find package "runtime" in any of:
/home/user/go/src/pkg/runtime (from $GOROOT)
/home/user/work/src/runtime (from $GOPATH)
Checking ~/go, I find fmt in ~/go/src/fmt and not ~/go/src/pkg/fmt
It feels like I am missing something crucial. Thankful for assistance.

如果您之前通过软件包管理器安装了Go，可能会有旧版本。检查go version并在需要时删除旧版本。
英文:
If you installed Go from a package manager before, you might have an old version. Check go version and remove the old version if needed.

对于已安装了 go 1.10.3 的 MacPorts 用户来说，它似乎没有正确安装。运行时标准包丢失了。我甚至尝试卸载并重新安装了一个干净的副本。所以我只是将其移除，并从 Google 获取了官方的 Darwin 二进制包：
英文:
For MacPorts users with e.g. go 1.10.3 installed, it didn't seem to be correctly installed for me. The runtime standard packages were missing. I even tried uninstalling and reinstalling a clean copy. So I just removed it and got the official darwin binary package from google:
