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。 我发现了一些导入包的源代码，如下所示：

import (
    "os"

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

但是，在每次构建项目时都会抛出错误：

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。 目前我正在尝试将这个项目构建到我的系统中。

编辑：

运行此命令go install或go get ：

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 .

如果您还没有设置任何 go 路径，这个问题很常见。 这是必要的。

我从您的命令行快照中假设您是 UNIX 用户。 Google 的官方文档建议您手动设置 go 路径。 $GOROOT 是可选的，但如果您尝试获取第三方库，则必须设置 $GOPATH。

编辑您的 ~/.bash_profile 以添加以下行：

export GOPATH=$HOME/work

然后注销并登录或使用source ~/.bash_profile您可以从这里阅读更多信息。 假设您的 Golang 包目录位于您的home目录内的work文件夹中。 工作文件夹的目录结构必须如下所示，

• 工作
  • 源文件
  • 包
  • 垃圾桶
