watch. doesn't work but watch specified file works. Why?

Error when using --watch.

adminsMacBook7:sass admin$ sass --watch. OptionParser::InvalidOption: invalid option: --watch. Use --trace for backtrace.

But this works : adminsMacBook7:sass admin$ sass --watch test.scss:test.css

Sass is watching for changes. Press Ctrl-C to stop. write test.css write test.css.map

Could anyone explain why?

Try

--watch .

in your terminal.

With watch, it might be confusing that with an invalid command. So keep a space between the period and the watch command :-)
