如何获得Go的远程软件包？

Question

I have problem with importing gin package into my Go project.

Code:

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
}

I'm using go get command to install gin package, but it doesn't work.

I have set proxy settings in git,so can this be a problem?

Answer 1

Try with:

  go get gopkg.in/gin-gonic/gin.v1

That will import a fixed version of that framework.

See for instance "Build RESTful API service in golang using gin-gonic framework"

But if you have proxy issue, that import should fail too.
As seen in "Building Go Web Applications and Microservices Using Gin", go get -u github.com/gin-gonic/gin should work too.

Try removing proxy directive in your .gitconfig.

Try instead setting HTTP_PROXY/HTTPS_PROXY (make sure to use http url in both cases for the variables, as I illustrate in "this answer")
