go - 构建时在 golang 中找不到包 "github.com/user../../"

Question

我正在尝试从 github 源代码构建一个项目。我发现一些源代码导入了如下所示的包:

import (
    "os"

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

但是在构建项目时每次都会报错:

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)

如何构建这个项目。目前我正在尝试构建这个 project进入我的系统。

这个问题已经有几年了。我遇到了同样的问题。我的解决方案是我需要运行 go mod init [name_of_main_go_file]，它会创建 go.mod 文件。然后你可以运行 go run .
