I want to use this package: github.com/go-sql-driver/mysql

I tried with:

go get -u github.com/go-sql-driver/mysql

It went right, but when I'm importing the package and running the code its gives me an error:

main.go:12:2: no required module provides package github.com/go-sql-driver/mysql: go.mod file not found in current directory or any parent directory; see 'go help modules'

In project root directory run

go mod init example.com/your-project-name

It will create go.mod file

module example.com/your-project-name

go 1.15

Then run

go get -u github.com/go-sql-driver/mysql

EDIT: As rustyx said in the comment, this is a deprecated approach and you might want to consider newer ones

You can do without the go.mod if your GOROOT and GOPATH environment variables are setted correctly
To do so, you can refer to What should be the values of GOPATH and GOROOT?

Also, you need to ensure that your IDE/text editor also recognize those two variables.
Note: In the case of an IDE (such as Goland), you might need to set it up manually. In the case of a text editor (ex: vscode), you can simply reload your project and it should do the trick.

Once this is done, you can validate that the content of your $GOPATH/github.com/go-sql-driver/mysql/ is present. If not, you can rerun your go get -u github.com/go-sql-driver/mysql command, reload your editor, and you should be alright
