The following tutorial column will introduce to you why it is no longer recommended to use GOPATH and how to use Go Modules. I hope it will be helpful to friends in need! Reason: With Go Modules

History:

An environment variable used to tell GO when compiling the project Where to read source files

Restriction rules:

Requires the project to be written under GOPATH

• Needs to create a directory based on the actual URL path of the project. For example, github.com/foo/bar => $GOPATH/src/github.com/foo/bar
  • There is no built-in version tracking for extension packages
With Go Modules

One line of command to migrate old projects

Only affects the development environment, not the production environment

• Compatible with GOPATH, you can still use GOPATH
• to Go Modules

version requirements>=1.11## according to your personal preferences.

• #go mod init

  Command initialization, such as:

mkdir myProject/
cd myProject
go mod init github.com/myGithubName/myProject

GOPATH project migration, such as:

mv ~/go/src/github.com/myGithubName/myProject ~/anywhere_else/
cd ~/anywhere_else/myProject
go mod init github.com/myGithubName/myProject

In addition, if you use Goland IDE, open Settings and go to Go -> Go Modules (vgo), check Enable Go Modules (vgo) Integration, otherwise the extension package will not be recognized.
