Hi, Philip.

The error was covered by my error message. After going one level deep, the
real error message is `Package lacks a file header `.
It occurred with the following code, not `package-install-file` (sorry for
the confusion).

``elisp
(with-temp-buffer
  (dired path)
  (ignore-errors (package-dir-info)))  ; error occurred this line
```

The test package I'm trying to install is located at
https://github.com/emacs-eask/cli/tree/master/test/jest/install/foo-mode.

Thanks!
