英文:
Go install: “Can't load package” (even though GOPATH is set)
问题
我刚刚开始学习Go编程语言，并使用网站上的Windows安装程序安装了Go。我通过使用go run hello.go进行了安装测试，一切正常。但是当我尝试构建我的第一个程序时出现了问题：
$ echo $GOROOT
C:\Go\
$ echo $GOPATH
/cygdrive/c/Users/Paul/Documents/Home/go
mkdir -p $GOPATH/src/hello
在该目录下，我有一个简单的hello.go程序：
package main
import "fmt"
func main() {
fmt.Printf("Hello, world.\n")
}
当我尝试构建和安装时出现问题：
$ go install hello
无法加载包：找不到任何位置的包“hello”：
C:\Go\src\hello（来自$GOROOT）
\cygdrive\c\Users\Paul\Documents\Home\go\src\hello（来自$GOPATH）
英文:
I'm just getting started with the Go programming language and installed Go using the Windows installer from the website. I tested installation by using go run hello.go and that works. The problem comes when I try to build my first program:
$ echo $GOROOT
C:\Go\
$ echo $GOPATH
/cygdrive/c/Users/Paul/Documents/Home/go
mkdir -p $GOPATH/src/hello
Inside that directory I have a simple hello.go program:
package main
import "fmt"
func main() {
fmt.Printf("Hello, world.\n")
}
The problem comes when I try to build and install:
$ go install hello
can't load package: package hello: cannot find package "hello" in any of:
C:\Go\src\hello (from $GOROOT)
\cygdrive\c\Users\Paul\Documents\Home\go\src\hello (from $GOPATH)

得分: 3
GOPATH 环境变量必须包含有效的路径。
\cygdrive\c\Users\Paul\Documents\Home\go\src\hello 不是 Windows 上的有效路径。
尝试将 GOPATH 设置为 c:\Users\Paul\Documents\Home\go。
英文:
GOPATH environment variable must contain valid path.
\cygdrive\c\Users\Paul\Documents\Home\go\src\hello is not a valid path on Windows.
Try setting GOPATH=c:\Users\Paul\Documents\Home\go instead.
