Can't seem to get started with Go and Echo

Trying to build a simple crud api with Golang and Echo and I can't get past the first tep in the Echo docs.

I run go get -u github.com/labstack/echo/...

then I create server.go:

package main

import (
    "net/http"

    "github.com/labstack/echo/v4"
)

func main() {
    e := echo.New()
    e.GET("/", func(c echo.Context) error {
        return c.String(http.StatusOK, "Hello, World!")
    })
    e.Logger.Fatal(e.Start(":1323"))
}

but when I try to run: go run server.go

I get this error:

server.go:6:2: cannot find package "github.com/labstack/echo/v4" in any of:
    /usr/local/Cellar/go/1.14.4/libexec/src/github.com/labstack/echo/v4 (from $GOROOT)
    /Users/dariusgoore/go/src/github.com/labstack/echo/v4 (from $GOPATH)

I get the same issue when I run go get before go mod init. Using the following commands, I can run the server successfully:

go mod init example.com/try-echo
go get
go run server.go

I just created a new project with the same main.go and it ran without any issue. I have listed the steps I followed.

package main

import (
    "net/http"

    "github.com/labstack/echo/v4"
)

func main() {
    e := echo.New()
    e.GET("/", func(c echo.Context) error {
        return c.String(http.StatusOK, "Hello, World!")
    })
    e.Logger.Fatal(e.Start(":1323"))
}

and used go.mod for dependencies downloads

go mod init

go get

go run main.go

and it ran without any error

I hope this helps. If it doesn't you can run go env and share the result of the command, which will help to debug further.

You need to enable GO111MODULE. To enable the module you need to run this command.

export GO111MODULE=on

After enabling it when you will run go run server.go then it will install the packages again after that the program will run as expected.
