Popover requires tooltip.js

Error message

Popover requires tooltip.js

What it means

Popover is defined in a separate file from tooltip and deliberately extends $.fn.tooltip.Constructor.DEFAULTS (see the $.extend right after the guard). At file-eval time it checks whether $.fn.tooltip exists; if tooltip.js was not loaded first, popover.js throws immediately so it fails loudly instead of producing a broken plugin later.

Solutions

1. Load bootstrap-tooltip.js before bootstrap-popover.js (or just load the full bootstrap.js bundle, which already orders them correctly).
2. If using a custom build tool, add tooltip as a dependency of popover.
3. Verify in the Network tab that tooltip.js returned 200.

Example fix

// before
<script src="bootstrap-popover.js"></script> <!-- tooltip.js missing -->

// after
<script src="bootstrap-tooltip.js"></script>
<script src="bootstrap-popover.js"></script>

if (typeof window.jQuery === 'undefined' || !$.fn.tooltip) {
  console.error('Load bootstrap-tooltip.js before bootstrap-popover.js (or use the full bootstrap.js).');
}

function popoverAvailable() {
  return typeof window.jQuery === 'function' && typeof $.fn.tooltip === 'function' && typeof $.fn.popover === 'function';
}

When it happens

Trigger: Including bootstrap-popover.js (or a custom build) without bootstrap-tooltip.js; concatenating bootstrap files in the wrong order; tooltip.js failing to load (404) while popover.js loads.

Common situations: Using the 'bootstrap.js' bundle usually avoids this — it happens with individually downloaded components, custom Bootstrap builds where tooltip was unchecked, or template pages that include popover but not tooltip.
