1. Install tesseract via brew on macOS 10.13.6
2. go mod init a new module and run the example provided in README.md

go.mod

module <root>/test

go 1.17

require github.com/otiai10/gosseract/v2 v2.3.1

require github.com/otiai10/mint v1.3.3 // indirect

main.go

package main

	"fmt"

	"github.com/otiai10/gosseract/v2"
)

func main() {
	client := gosseract.NewClient()
	defer client.Close()
	client.SetImage("/Users/<user>/Desktop/test.jpg")
	text, _ := client.Text()
	fmt.Println(text)
	// Hello, World!
