Errors running first Go project on local machine

Question

I've installed the latest version of Go on my local machine, downloaded the source code from https://github.com/rrrkren/topshot-sales, and placed the project code in my GOPATH.

When I run it go run go/main.go in my command prompt, I get these errors

go\main.go:8:2: no required module provides package github.com/onflow/flow-go-sdk/client: go.mod file not found in current directory or any parent directory; see 'go help modules'
go\main.go:6:2: no required module provides package github.com/rrrkren/topshot-sales/topshot: go.mod file not found in current directory or any parent directory; see 'go help modules'
go\main.go:9:2: no required module provides package google.golang.org/grpc: go.mod file not found in current directory or any parent directory; see 'go help modules'

Even though the go.mod file is located in the current directory. I would like to be able to download this project and keep it on my local machine, so I can edit the source code whenever I want. How can I do that?

Answer 1

This is what worked for me.

Step 1. Delete any previous Go version if you are doubtful about having it configured properly.

Step 2. Install new Go version. Download the binary release (Go) from here Go Binary Download

Note: In order to delete and install the new Go version you can use these steps - Go Deletion and Installation, they worked for me. Also the version I am currently using is 1.16.3.

Step 3. After completing step 1 and step 2, run the following command in a terminal:

go env -w GO111MODULE=auto

This should do it.
