How to start a project correctly in Goland

The following tutorial column from golang will introduce to you how to correctly start a project in Goland. I hope it will be helpful to friends in need!

                                                                                                               

Because Error: cannot not find package will appear every time you create a project and build, so this article was born

1. Preparation before creating the project

1.1 Installgolang,goland

1.2 View GOPATH

echo $GOPATH# 如果需要更改GOPATH可以根据以下操作 (Mac)vim ~/.bash_profileexport GOPATH=#你的目标地址
#保存:wq
#刷新
source ~/.bash_profile

1.3 Create pkg,bin## in the $GOAPTH folder #,srcThree folders

mkdir $GOPATH/pkg  # pkg存放编译后的包文件
mkdir $GOPATH/src  # src存放项目源文件,我们的项目目录一般在该文件中
mkdir $GOPATH/bin  # bin存放编译后的可执行文件

You can see that our directory structure is like this

$GOAPTH
    |-bin    |-pkg    |-src       |-(项目名称，之后要创建的)

1.4 Turn on the proxy (because of domestic downloads The package is slow or fails. Configuring the proxy can better help us obtain third-party packages)

Mac

vim ~/.bash_profile #打开 bash_profile

# 将以下代码复制到 bash_profile 中export GO111MODUL=on  # 开启 go moduleexport GOPROXY=https://goproxy.io  # 设置国内代理

#保存:wq

#刷新
source ~/.bash_profile

Windows

set GO111MODUL=on  # 开启 go moduleset GOPROXY=https://goproxy.io  # 设置国内代理，推荐使用该地址

1.5 Check whether the configuration is successful

# 输入命令
go env

1.6 Open Goland (don’t create a project yet)

Configuration settings
• Setting -> Plugins... -> Go -> GOPATH
  ##Uncheck
index entire GOPATH
• (After checking, the current Project as GOPATH)Golang will automatically search for the project code in the
src
• directory of $GOPATHCheck whether the agent is also configured in Goland

2. Create a project

2.1 Create a project based on Goland’s new

2.2 You only need to create it in the $GOPATH/src directory.

If an error occurs, you can create it in the

Terminal
• of the project. Configuration starting from 1.4
