Question

我试图在jekyll网站上安装lunr.js，我收到此错误：

我试图按照https://github.com/slashdotdash/jekyll-lunr-js-search上的说明操作，但我对Jekyll来说有些新鲜，所以我可能不会理解一切。有两种方法可以安装它：使用rubygem或直接下载预先构建的插件文件。我选择了后者。以下是我采取的步骤：

将回购克隆克隆到我的本地机器。
将jekyll_lunr_js_search.rb和jekyll_lunr_js_search文件夹移至我的_plugins目录。
下载缩小的search.min.js文件（其中包含许多其他js）并将其添加到我的javascript目录中。
将jquery.lunr.search.js添加到我的javascript目录。
在我的default.html文件中添加了以下引用：

<script src="{{ "/javascripts/search.min.js" | prepend:site.baseurl }}">
    </script>
    <script src="{{ "/javascripts/jquery.lunr.search.js" | prepend:site.baseurl}}"></script>

此脚本也添加到我的default.html（通过包含）：

 <script type="text/javascript">
    $(function() {
    $('#search-query').lunrSearch({
         indexUrl: '/js/index.json',   // Url for the .json file containing search index data
          results : '#search-results',  // selector for containing search results element
          entries : '.entries',         // selector for search entries containing element (contained within results above)
          template: '#search-results-template'  // selector for Mustache.js template
        });
      });
    </script>

将此搜索表单添加到页面：

 <div id="search">
      <form action="/search" method="get">
        <input type="text" id="search-query" name="q" placeholder="Search" autocomplete="off">
      </form>
        </div>

，这会在同一页面上的表单下方生成容器：

 <section id="search-results" style="display: none;">
      <p>Search results</p>
      <div class="entries">
      </div>
    </section>

和它下面的胡子模板：

 {% raw %}
    <script id="search-results-template" type="text/mustache">
      {{#entries}}
        <article>
          <h3>
            {{#date}}<small><time datetime="{{pubdate}}" pubdate>{{displaydate}}</time></small>{{/date}}
            <a href="{{url}}">{{title}}</a>
          </h3>
        </article>
      {{/entries}}
    </script>
    {% endraw %}

现在，当我构建我的jekyll网站时，我收到了之前列出的错误。（没有插件，我不会得到这个错误。）有什么想法吗？我真的需要在我的网站上使用搜索功能，而这个功能似乎是最好的。

Answer 1

首先尝试安装libv8 Ruby gem。

gem install libv8 -v '3.16.14.7'

或

gem install libv8 -v '3.16.14.7' -- --with-system-v8

然后安装最新版本的jekyll_lunr_js_search gem。

gem install jekyll-lunr-js-search

最后，在Jekyll网站的_config.yml配置文件中包含对插件gem的引用。

gems: ['jekyll-lunr-js-search']

为什么我在Jekyll上安装lunr.js搜索时出错？
