bootstrap-vue: most Icons isnt showing

问题

I import all icons (as documentation says):

import Vue from 'vue'
import { BootstrapVue, BootstrapVueIcons } from 'bootstrap-vue'

Vue.use(BootstrapVue)
Vue.use(BootstrapVueIcons)

When I copy some code from site - icon is working great.

This example is ok:

<b-icon icon="exclamation-circle-fill" variant="info"></b-icon>

But when Im just changing the icon name, it disappears... It looks like some icons does not exist...

This doesnt work:

<b-icon icon="cart" variant="info"></b-icon>

How to fix it?
