构建时在golang中找不到包“github.com/user../../”

Question

I am trying to build a project from github source code. I have found some source code importing a package something like below:

import (
    "os"

    "github.com/bivas/rivi/commands"
    "github.com/mitchellh/cli"
)

However, while building a project every time it throws an error:

user-MacBook-Pro:rivi user$ go build rivi.go
rivi.go:6:2: cannot find package "github.com/bivas/rivi/commands" in any of:
        /usr/local/Cellar/go/1.7.5/libexec/src/github.com/bivas/rivi/commands (from $GOROOT)
        ($GOPATH not set)
rivi.go:8:2: cannot find package "github.com/mitchellh/cli" in any of:
        /usr/local/Cellar/go/1.7.5/libexec/src/github.com/mitchellh/cli (from $GOROOT)
        ($GOPATH not set)

how to build this project. Currently I am trying to build this one project into my system.

EDITED:

After running this command go install or go get :

Answer 1

This question is a few years old now. I was experiencing the same problem. The solution for me was that I needed to run go mod init [name_of_main_go_file] , which creates the go.mod file. Then you can run go run .

This problem common if you haven't setup any go path yet. It is necessary.

I am assuming from the command line snap of yours, that you are a UNIX user. Googles official doc recommend that you setup your go path manually . $GOROOT is optional but $GOPATH has to be set if you are trying to get third party libraries.

Edit your ~/.bash_profile to add the following line:

export GOPATH=$HOME/work

Then logout and login or use source ~/.bash_profile You can read more from here . Assuming your Golang package directory is in work folder inside your home directory. The directory structure of work folder has to look like this,

• work
  • src
  • pkg
  • bin
