我的HTML如下：
<ul class="list-inline">
<li class="tag" ngb-dropdown auto-close="outsideClick"
*ngFor="let item of ['Elastic Search','Database Theory','CVS'];
let $index=index;"
[ngClass]="{'default-tag': $index==0,'matched-tag': $index==1,'unmatched-tag': $index==2 }">
<a href ngb-dropdown-toggle id="desiredSkill{{$index}}">
<i class="bi_interface-tick following"></i> {{item}} <i class="bi_interface-more tag-menu-icon"></i>
</a>
<ul class="dropdown-menu tag-menu" ngb-dropdown-menu [aria-labelledby]="desiredSkill{{$index}}">
<li><a href>Follow Skill</a></li>
<li><a href>Related Jobs</a></li>
</ul>
</li>
</ul>
但是当我运行我的应用程序时,我得到以下错误：
main.browser.ts:25Error: Template parse errors:

似乎它应该是：
[attr.aria-labelledby]="'desiredSkill' + $index"
要么
attr.aria-labelledby="desiredSkill{{$index}}"
