You're not into a project

[nspring]

When running "rubocop-autocorrect-current-file" on a standalone .rb file, I get the error "You're not into a project". My elisp literacy is not so good, but it seems that the code wants to allow running outside a project, but triggers an exception when no project root can be found:

    (let ((default-directory (or (rubocop-project-root 'no-error) default-directory)))

Within a rails project, I have no trouble.
