GO：Hello World中导入错误

Question

My test program test.go:

package main

import "fmt"
func main() {
  fmt.Printf("Hello
")
}

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!

Answer 1

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.

• Getting Started: Install the Go tools
• Related: what should be the values of GOPATH and GOROOT?
