Jekyll错误“液体异常:未定义的方法‘编码’为nil:NilClass in _layout/post.html”
Jekyll错误“液体异常:未定义的方法‘编码’为nil:NilClass in _layout/post.html”
提问于 2015-07-22 18:26:25
在尝试运行jekyll build或jekyll serve时获取以下错误
Liquid Exception: undefined method 'encoding' for nil:NilClass in _layouts/post.html
jekyll 2.5.3 | Error: undefined method 'encoding' for nil:NilClass它看起来是RVM/ruby文件的问题吗？(请参阅下面的--跟踪日志)，但我并没有真正按代码操作(尤其是在任何ruby文件中)，也没有在最后几次提交中编辑‘/_layout/post.html’，这只是弹出的。
虽然主分支在此错误发生之前已经进行了最后一次提交，但以下是Github：https://github.com/ryanstraits/ryanstraits.github.io上的存储库。
不是一个严肃的编码器，所以我有点困惑。任何帮助都会很好。
下面是我运行jekyll build --trace时得到的信息

对我来说问题是：
{{ cgi_escape_title = page.title | cgi_escape }}在我的_layouts/default.html中，对于没有page.title的页面。
一个解决方案是这样做：
{{ page.title | default: "" | cgi_escape }}它将nul标题转换为""，或者如果您感到更详细：
{% if page.title %}
{% assign cgi_escape_title = page.title | cgi_escape %}
{% else %}
{% assign cgi_escape_title = '' %}
{% endif %}
{{ cgi_escape_title }}在Jekyll 3.0.3上测试。

发现了这个问题:我的很多帖子都是使用"Wordpress to Jekyll“转换器导入的，看起来它在前面的几个帖子中留下了"title:”字段中的空白。只是希望这个错误能更具体一点。
我想今天的教训是:伙计们，不要让你的前额空白！
