</blockquote></div><br></div><div class="gmail_extra">That's a fair point, but if the user first runs `stack setup` (which I'd recommend in any usage of this line), it does become side-effect-free. Regarding #2325: it might make sense to have `stack path` simply fail if no project file is found, but user intent is a bit unclear on that point.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Michael</div></div>
