How do I install requirements in Go? "cannot find package"

问题

我是你的中文翻译助手,以下是翻译好的内容:

我是Go的新手,正在尝试使用最少的文档设置一个Go项目:https://github.com/alphagov/metadata-api

我已经克隆了它,但是当我尝试运行go build时,我收到以下警告:

main.go:8:2: 无法在以下任何位置找到包“github.com/Sirupsen/logrus”:
	/usr/local/Cellar/go/1.3.3/libexec/src/pkg/github.com/Sirupsen/logrus(来自$GOROOT)
	/Users/me/go/src/github.com/Sirupsen/logrus(来自$GOPATH)
main.go:14:2: 无法在以下任何位置找到包“github.com/alphagov/metadata-api/content_api”:
	/usr/local/Cellar/go/1.3.3/libexec/src/pkg/github.com/alphagov/metadata-api/content_api(来自$GOROOT)
	/Users/me/go/src/github.com/alphagov/metadata-api/content_api(来自$GOPATH)

我猜这是因为我没有安装Go的依赖包的原因?

我的GOPATH已经设置好了:

metadata-api$ echo $GOPATH
/Users/me/go

而Go可执行文件在以下位置:

metadata-ape$ echo $PATH
....:/Users/me/go/bin

我需要做什么来帮助Go找到这些包?

英文:

I'm new to Go and I'm trying to set up a Go project with minimal documentation: https://github.com/alphagov/metadata-api

I've cloned it, but when I try go build I get the following warnings:

main.go:8:2: cannot find package "github.com/Sirupsen/logrus" in any of:
	/usr/local/Cellar/go/1.3.3/libexec/src/pkg/github.com/Sirupsen/logrus (from $GOROOT)
	/Users/me/go/src/github.com/Sirupsen/logrus (from $GOPATH)
main.go:14:2: cannot find package "github.com/alphagov/metadata-api/content_api" in any of:
	/usr/local/Cellar/go/1.3.3/libexec/src/pkg/github.com/alphagov/metadata-api/content_api (from $GOROOT)
	/Users/me/go/src/github.com/alphagov/metadata-api/content_api (from $GOPATH)

I'm guessing this is because I haven't installed the Go equivalent of requirements?

My GOPATH is set:

metadata-api$ echo $GOPATH
/Users/me/go

And the Go executable is in

metadata-ape$ echo $PATH
....:/Users/me/go/bin

What do I need to do to help Go find these packages?

你应该先安装包:

尝试运行以下命令:

$ go get github.com/Sirupsen/logrus

并检查你的 $GOPATH 目录。

这个项目使用 gom 作为包管理器,

确保你已经安装了 gom

或者尝试运行以下命令:

$ gom install

我认为你的 $GOPATH$PATH 设置不正确,$GOPATH 环境变量指定了你的工作空间的位置,以下是我的路径设置:

export GOROOT=$HOME/bin/go
export GOBIN=$GOROOT/bin
export GOPATH=$HOME/golang
export PATH=$PATH:$GOBIN
英文:

You should install package first:

try

$ go get github.com/Sirupsen/logrus

and check you $GOPATH dir

This project use gom as the package manager,

Make sure you have installed gom

or try this command

$ gom install 

I think your $GOPATH and $PATH settings are incorrect, the $GOPATH environment variable specifies the location of your workspace, these are my path settings:

export GOROOT=$HOME/bin/go
export GOBIN=$GOROOT/bin
export GOPATH=$HOME/golang
export PATH=$PATH:$GOBIN

我遇到了类似的问题,然后使用了以下命令来解决:

export GO111MODULE=on

I had similar issue and

export GO111MODULE=on 

helped.

当你需要让你的代码执行一些可能已经由其他人实现的功能(在Github或其他地方的软件包中),你应该在你的文件夹中初始化一个go mod文件。

以本例为例,我将使用example.com/module。

go mod init example.com/module

添加新的模块要求和摘要:

go mod tidy

运行你的程序:

go run .

更多详情,请参阅https://golang.org/doc/tutorial/getting-started。

英文:

When you need your code to do something that might have been implemented by someone else (in Github or a package somewhere else), You should initialize a go mod file inside of your folder.)

For the purposes of this example, I'll just use example.com/module.

go mod init example.com/module

Add new module requirements and sums:

go mod tidy

Run your program:

go run .

For more details, see https://golang.org/doc/tutorial/getting-started.

我能够通过以下方式解决类似问题:

 export GOPATH=~/go
 go get github.com/profile/repository 
 (例如:github.com/Sirupsen/logrus)
英文:

Was able to fix the similar issue in Go 1.13.7 by typing:

 export GOPATH=~/go
 go get github.com/profile/repository 
 (e.g. github.com/Sirupsen/logrus)

从Go 1.13开始,模块模式将成为所有开发的默认模式。

在使用模块时,不再使用GOPATH来解析导入。然而,它仍然用于存储已下载的源代码(在GOPATH/pkg/mod中)和已编译的命令(在GOPATH/bin中)。

英文:

"...Starting in Go 1.13, module mode will be the default for all development..."

"...When using modules, GOPATH is no longer used for resolving imports. However, it is still used to store downloaded source code (in GOPATH/pkg/mod) and compiled commands (in GOPATH/bin)..."
