Question

我注意到有几篇与此相似的帖子，但不明白如何解决这个问题。

我安装了ruby 1.9.3-p392的rbenv，当我运行jekyll时出现以下错误--server：

我很困惑，不知道从哪里开始解决这个问题。我也在使用jekyll版本（0.12.1）。

以下是我的sitemap.xml：

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="/sitemap.xsl"?>
<urlset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd" xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">

<lastmod>{{ site.time | date_to_xmlschema }}</lastmod>
<changefreq>daily</changefreq>

<url>
<loc>http://aceeightofspades.com{{ post.url }}/</loc>
<lastmod>{{ post.date | date_to_xmlschema }}</lastmod>
<changefreq>weekly</changefreq>
<priority>0.8</priority>
</url>
</urlset>

Answer 1

您似乎正在尝试为不存在的顶级<url>对象创建post条目。我认为你想要的是循环你的帖子并为每个帖子创建一个条目。

这样的事情：

{% for post in site.posts %}
<url>
  <loc>http://aceeightofspades.com{{ post.url }}/</loc>
  <lastmod>{{ post.date | date_to_xmlschema }}</lastmod>
  <changefreq>weekly</changefreq>
  <priority>0.8</priority>
</url>
{% endfor %}

这会将您的第二个<url>块与{% for post in site.posts %}和{% endfor %}包裹起来，以便在该块post内不再为空。

为什么jekyll --server返回错误
