Update: 已解决.

将./themes/yilia/layout/_partial/post/category.ejs改为：

<% if (post.categories && post.categories.length){ %>
<div class="article-category tagcloud">
    <i class="icon-book icon"></i>
    <ul class="article-tag-list">
        <% post.categories.forEach(function(tag, i){ %>
        <% if (tag.hasOwnProperty('name')){ %>
        <li class="article-tag-list-item">
            <a href="<%= config.root %><%= tag.path %>/" class="article-tag-list-link color<%= tag.name.length % 5 + 1 %>">
                <%-tag.name%></a>
        </li>
        <% } %>
        <% }) %>
    </ul>
</div>
<% } %>

将./themes/yilia/layout/_partial/post/tag.ejs改为：

<% if (post.tags && post.tags.length){ %>
<div class="article-tag tagcloud">
    <i class="icon-price-tags icon"></i>
    <ul class="article-tag-list">
        <% post.tags.forEach(function(tag, i){ %>
        <% if (tag.hasOwnProperty('name')){ %>
        <li class="article-tag-list-item">
            <a href="javascript:void(0)" class="js-tag article-tag-list-link color<%= tag.name.length % 5 + 1 %>">
                <%-tag.name%></a>
        </li>
        <% } %>
        <% }) %>
    </ul>
</div>
<% } %>
