Could not find compatible versions

Because every version of google-cloud-spanner depends on
google-cloud-spanner-admin-instance-v1 ~> 1.6
  and Gemfile depends on google-cloud-spanner >= 0,
  google-cloud-spanner-admin-instance-v1 ~> 1.6 is required.
So, because Gemfile depends on google-cloud-spanner-admin-instance-v1 ~> 2.0,
  version solving has failed.
