import “github.com/gin-gonic/gin“ 爆红

package main
​
import "github.com/gin-gonic/gin"
​
func main() {
    r := gin.Default()
    r.GET("/ping", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "message": "pong",
        })
    })
    r.Run() // listen and serve on 0.0.0.0:8080 (for windows "localhost:8080")
}

如果 import “github.com/gin-gonic/gin” 爆红，解决办法如下：

go mod init gin
go mod edit -require github.com/gin-gonic/gin@latest
go mod vendor

 vscode问题 go: updates to go.mod needed, disabled by -mod=readonly : packages.Load error

解决方法：

如果已经设置了gomod环境，只需要更新mod依赖的modules

go mod tidy
