Go Path Issues Installing Sensu Go from Source

Sensu Go
1

Installing Sensu Go with the MIT license from source (https://github.com/sensu/sensu-go) has proved challenging. Following the directions presented in the readme.md does not let me install the service and instead I get a tremendous amount of go pathing issues.

warning: GOPATH set to GOROOT (/home/ubuntu/go) has no effect
go run: no go files listed

As seen above my Go path is set to “/home/ubuntu/go”, but it doesn’t seem to recognize “sensu-go/cmd/sensu-backend/main.go” is a Go file.

When I try to build directly (not using the “run” command) I get the following pathing issues:

There seems to be an ongoing issue with this regarding Go and Sensu-Go:

Using GOROOT and putting the source under your GOPATH is no longer required with newer versions of Go.

Here are the steps I used and was able to compile from source (Using Go 1.13.1 installed in /usr/local/go on Fedora 30) :

$ which go
/usr/local/go/bin/go
$  go version
go version go1.13.1 linux/amd64
$ env | grep GO
GOPATH=/home/todd/go
$ go build ./cmd/sensu-agent

Thank you Todd, I still have no luck following the steps above:

It seems like the main.go has the wrong path to the build files or something of that nature.

Ah, your version of Go is way outdated and doesn’t support the new modules paradigm. You will need a newer version of Go. I suggest the latest iteration of 1.13.

Perfect! That worked for me, thank you Todd!
