構建時在golang中找不到包“github.com/user../../”

Question

我正在嘗試從 github 源代碼構建一個項目。 我發現了一些導入包的源代碼，如下所示：

import (
    "os"

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

但是，在每次構建項目時都會拋出錯誤：

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)

如何構建這個項目。 目前我正在嘗試將這個項目構建到我的系統中。

編輯：

運行此命令go install或go get ：

這個問題已經有幾年了。 我遇到了同樣的問題。 我的解決方案是我需要運行go mod init [name_of_main_go_file] ，它會創建 go.mod 文件。 然后你可以運行go run .

如果您還沒有設置任何 go 路徑，這個問題很常見。 這是必要的。

我從您的命令行快照中假設您是 UNIX 用戶。 Google 的官方文檔建議您手動設置 go 路徑。 $GOROOT 是可選的，但如果您嘗試獲取第三方庫，則必須設置 $GOPATH。

編輯您的 ~/.bash_profile 以添加以下行：

export GOPATH=$HOME/work

然后注銷並登錄或使用source ~/.bash_profile您可以從這里閱讀更多信息。 假設您的 Golang 包目錄位於您的home目錄內的work文件夾中。 工作文件夾的目錄結構必須如下所示，

• 工作
  • 源文件
  • 包
  • 垃圾桶
