What should I do if golang cannot find the package

Problem description

Usego buildCompile* The .go program cannot find the package. The window information is as follows:

$GOPATH>go build stacker.go
stacker.go:18:2: cannot find package “stack” in any of:
D:\Go\src\stack (from $GOROOT)
$GOPATH\src\stack (from $GOPATH)
$GOPATH>go version
go version go1.11.2 windows/amd64

Ideas to solve the problem

It seems that the GOPATH environment variable is not set correctly.

Problem Analysis

go build prompts that the corresponding library file cannot be found in the src stack directory.

The package content of stacker.go is roughly as follows

package main
import (
"fmt"
"stacker/stack"
"strings"
)

So try to modify $GOPATH to the same level directory as src, and then use go build stacker. You can find the corresponding stack package normally by compiling go.

Problem Summary

The go compiler will search for the package in the src directory in the current directory by default. If there is no src directory, the compiler cannot find the corresponding package.
