Running go install results in error
问题
我在Windows上安装了Go。GOPATH设置为：
c:\go-workspace
我在这个目录下有一个名为login.go的文件：
C:\go-workspace\src\github.com\llnw\login
login.go的内容如下：
package main
func main() {
fmt.Printf("login\n")
}
我尝试使用以下命令进行构建：
go build github.com/llnw/login/login
但是我得到了以下错误：
无法加载包：找不到任何位置的包“github.com/llnw/login/login”：
C:\Go\src\github.com\llnw\login\login（来自$GOROOT）
C:\go-workspace\src\github.com\llnw\login\login（来自$GOPATH）
我做错了什么？
英文:
I installed go on Windows. GOPATH is set to this:
c:\go-workspace
I have file called login.go in this directory:
C:\go-workspace\src\github.com\llnw\login
login.go contains this:
package main
func main() {
fmt.Printf("login\n")
}
I tried the following to build:
go build github.com/llnw/login/login
But I get this error:
can't load package: package github.com/llnw/login/login: cannot find package "github.com/llnw/login/login" in any of:
C:\Go\src\github.com\llnw\login\login (from $GOROOT)
C:\go-workspace\src\github.com\llnw\login\login (from $GOPATH)
What am I doing wrong?

从go build -h中：
用法：build [-o 输出] [-i] [构建标志] [包]
Build编译由导入路径指定的包，以及它们的依赖项，但不安装结果。
如果build的参数是一组.go文件，build将把它们视为指定单个包的源文件列表。
在你的例子中，github.com/llnw/login/login既不像一个包，也不像一组.go文件。可能你是在寻找这个：
go build github.com/llnw/login
假设当你执行这个命令时，相对路径github.com/llnw/login存在。
英文:
From go build -h:

In your example, github.com/llnw/login/login looks neither like a package, nor a list of .go files. Probably you're looking for this:
go build github.com/llnw/login
Assuming that when you execute this command, the relative path github.com/llnw/login exists.
