go install: no install location for directory outside GOPATH

I installed the Go, then added path requirements to my .bash_profile:

• export PATH=$PATH:/usr/local/go/bin
• export GOPATH=$HOME/go

I then setup the correct folders:

I also created a projected called tire.
The contents for main.go are simply:

package main

import "fmt"

func main() {
  fmt.Println("Hello, world!")
}

I always get the following error when I try to run go install:

go install: no install location for directory /Users/Daryl/go/src/tire outside GOPATH

Here's what I get when I run go env:

GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/Users/daryl/go"
GORACE=""
GOROOT="/usr/local/go"
GOTOOLDIR="/usr/local/go/pkg/tool/darwin_amd64"
TERM="dumb"
CC="clang"
GOGCCFLAGS="-g -O2 -fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fno-common"
CXX="clang++"
CGO_ENABLED="1"

Any help would be appreciated.

When you run go install Go looks for $GOBIN env variable path. Either you need to set your $GOBIN to $GOPATH/bin

$ export GOBIN=$GOPATH/bin

and/or add $GOBIN to your OS search path

$ export PATH=$PATH:$GOBIN

To use the command without getting the error.

The problem was as James Henstridge commented, for some reason there was an issue with my user directory name case. Even though the directory is lowercase, I had to make it capitalized.

This worked:

GOPATH=/Users/Daryl/go

This didn't:

GOPATH=$HOME/go

However, since moving to a rMBP from my iMac, I had no problems whatsoever setting up Go, so, to this day, I'm not sure what was going on, but in that instance the capitalization fixed it.

I had the same problem in Windows 10,

So I set a system variable named GOBIN
with absolute value F:\go\bin.

Then ran go install main.go and everything worked perfectly fine!
