Tfenv: Cannot find .terraform-version on OSX

Using tfenv 0.6.0. I installed tfenv using brew install tfenv.

I have this in my .terraform-version

terraform {
  required_version  = ">= 0.10.0, <0.12.3"
}

✗ tfenv install
tfenv: tfenv-install: [ERROR] No versions matching '' found in remote

✗ cat /usr/local/Cellar/tfenv/0.6.0/libexec/tfenv-version-file
✗ find_local_version_file() {
  local root="${1}"
  while ! [[ "${root}" =~ ^//[^/]*$ ]]; do
    if [ -e "${root}/.terraform-version" ]; then
      echo "${root}/.terraform-version"
      return 0
    fi
    [ -n "${root}" ] || break
    root="${root%/*}"
  done
  return 1
}
✗ find_local_version_file
✗find_local_version_file .
./.terraform-version

I believe the issue is with the path sent to find_local_version_file.
