Cannot install terracost with go 1.18

[trinitronx]

Steps to Reproduce:

• Using go version: go version go1.18.1 darwin/arm64

  • Run: go install github.com/cycloidio/terracost@latest:

  • Install fails with error message:

    go: github.com/cycloidio/terracost@latest (in github.com/cycloidio/[email protected]):
    	The go.mod file for the module providing named packages contains one or
    	more replace directives. It must not contain directives that would cause
    	it to be interpreted differently than if it were the main module.
    

go.mod file contains:

replace github.com/hashicorp/terraform => github.com/hashicorp/terraform v0.15.3

Expected result:

Installation of terracost should work on Go >= 1.16

GO111MODULE=off Workaround fails on missing hashicorp/terraform/configs:

• Force using GOPATH install behavior with:

  • export GO111MODULE=off; go get github.com/cycloidio/terracost

  • Returns error message:

    cannot find package "github.com/hashicorp/terraform/configs" in any of:
      /opt/homebrew/Cellar/go/1.18.1/libexec/src/github.com/hashicorp/terraform/configs (from $GOROOT)
      /Users/exampleuser/src/pub/go/src/github.com/hashicorp/terraform/configs (from $GOPATH)
    

• Similar issues when trying to forcibly install terraform + dependencies to GOPATH via go get:

  • export GO111MODULE=off; go get

  • Returns more errors:

    export GO111MODULE=off;  go get github.com/hashicorp/terraform

Could you confirm https://github.com/cycloidio/terracost/pull/75/ is fixing your problem?

I am not super-familiar with golang, so not sure if I am doing something wrong, but I seem to have the same problem:

$ go get github.com/cycloidio/terracost@ff0b0053
go: go.mod file not found in current directory or any parent directory.
        'go get' is no longer supported outside a module.
        To build and install a command, use 'go install' with a version,
        like 'go install example.com/cmd@latest'
        For more information, see https://golang.org/doc/go-get-install-deprecation
        or run 'go help get' or 'go help install'.
