Cannot install Battlesnake CLI for Go 1.11 (cannot find package hashicorp/hcl/hcl/printer)

[jeffchase]

~/battlesnake$ go version
go version go1.11.6 linux/amd64
~/battlesnake$ go get github.com/BattlesnakeOfficial/rules/cli/battlesnake
package github.com/hashicorp/hcl/hcl/printer: cannot find package "github.com/hashicorp/hcl/hcl/printer" in any of:
        /usr/lib/go-1.11/src/github.com/hashicorp/hcl/hcl/printer (from $GOROOT)
        /home/jnchase/go/src/github.com/hashicorp/hcl/hcl/printer (from $GOPATH)

See hashicorp/hcl#449

Does this project need an update? (I know nothing about Go)

Ah, you'll want to update your Go install to one that supports Go Modules (1.11 does not by default).

Using Go 1.11:

~ docker run -it --rm golang:1.11
root@76e45262ccf8:/go# go get github.com/BattlesnakeOfficial/rules/cli/battlesnake
package github.com/hashicorp/hcl/hcl/printer: cannot find package "github.com/hashicorp/hcl/hcl/printer" in any of:
	/usr/local/go/src/github.com/hashicorp/hcl/hcl/printer (from $GOROOT)
	/go/src/github.com/hashicorp/hcl/hcl/printer (from $GOPATH)

Using Go 1.16 (latest):

~ docker run -it --rm golang:1.16
root@af51dbc9327f:/go# go get github.com/BattlesnakeOfficial/rules/cli/battlesnake

Thanks for the quick reply!

I was able to get it to work with go 1.14 (latest version in debian backports) by setting GO111MODULE=on:

Looks like there's a way to make it work with 1.11 as well by first adding a go.mod file but I've learned enough for now.

Thanks!
