英文:
Go: error on import in hello world
问题
我的测试程序test.go：
package main
import "fmt"
func main() {
fmt.Printf("Hello\n")
}
运行go run test.go会出现错误：
# io
pack: 无法打开 $WORK/io/_obj/_go_.6
# strconv
pack: 无法打开 $WORK/strconv/_obj/_go_.6
环境：
go version devel +715674f61ae8 Tue Jan 29 13:34:18 2013 -0800 linux/amd64
GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOGCCFLAGS="-g -O2 -fPIC -m64 -pthread"
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/usr/local/google/home/igord/incub/web"
GOROOT="/opt/go"
GOTOOLDIR="/opt/go/pkg/tool/linux_amd64"
CGO_ENABLED="1"
但是我从go网站上下载了这个版本（特色）RELEASE 1.0.3！
英文:
My test program test.go:
package main
import "fmt"
func main() {
fmt.Printf("Hello\n")
}
Running this go run test.go finishes with errors:
# io
pack: cannot open $WORK/io/_obj/_go_.6
# strconv
pack: cannot open $WORK/strconv/_obj/_go_.6
Environment:
go version devel +715674f61ae8 Tue Jan 29 13:34:18 2013 -0800 linux/amd64
GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOGCCFLAGS="-g -O2 -fPIC -m64 -pthread"
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/usr/local/google/home/igord/incub/web"
GOROOT="/opt/go"
GOTOOLDIR="/opt/go/pkg/tool/linux_amd64"
CGO_ENABLED="1"
But I downloaded this version from (featured) RELEASE 1.0.3 on the go site!

由评论中的各种解决方法，但为了记录：安装Go的二进制发行版到非默认位置需要正确设置$GOROOT和$GOPATH。

Resolved by various in comments, but for the record: installing a binary distribution of Go to a location other than the default requires setting $GOROOT and $GOPATH correctly.
