How can I get remote package for Go?

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?

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")

@ЮрийШиповалов Did you set the environment variable `HTTP_PROXY/HTTPS_PROXY`? Did you use an http URL for the proxy? – VonC Aug 16 '17 at 08:53

@ЮрийШиповалов So the go get has worked? (sice you do have a github.com\gin-gonic\gin). Can you try glide or govendor (https://github.com/gin-gonic/gin/issues/757#issuecomment-265369437) in order to make sure gin has all its dependencies? – VonC Aug 16 '17 at 10:59

Fixed version is not that important! The: $ go get github.com/gin-gonic/gin Should work correctly!! Fixed version is for when you want n specific version!
