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)

Setting -> Plugins... -> Go -> GOPATH
##Uncheck
(After checking, the current Project as GOPATH)Golang will automatically search for the project code in the
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

of the project. Configuration starting from 1.4

Mastering the strings package in Go language can improve text processing capabilities and development efficiency. 1) Use the Contains function to check substrings, 2) Use the Index function to find the substring position, 3) Join function efficiently splice string slices, 4) Replace function to replace substrings. Be careful to avoid common errors, such as not checking for empty strings and large string operation performance issues.
