How can I match an .npmrc file with gulp.src?

Question

I've been trying to use a glob in gulp.src to match all files, including dotfiles, and specifically .npmrc files. I've tried the following patterns;

gulp.src('/path/to/my/files/**/{*,.*}')

gulp.src('/path/to/my/files/**/*', {dot: true})

gulp.src('/path/to/my/files/.npmrc')

None of those patterns worked. More details can be found on GitHub.

Does anyone know why .npmrc files aren't being matched by these patterns? Does anyone know how to match them?
