ruby - 杰基尔服务错误 : no implicit conversion of nil into String

Question

我用这个错误搜索了 jekyll。jekyll 处理页面时似乎出现了 ruby​​ 错误，但我根本不了解 ruby​​。

杰基尔版本 1.3.1

我什至重新安装了 ruby​​ 和 jekyll，但结果没有改变。

更新:
在我将 jekyll 从 1.31 降级到 1.20 后，这个错误消失了
注意:我的网站是用 jekyll 1.20 创建的，所以它不能用 1.3.1 构建？这是核心问题吗？

更新测试样本
test repo
从 1.20 到 1.30 完美运行，从 1.3.1 到 1.4.3 损坏。

Answer 1

您的 ArchivePage#initialize 没有设置所需的属性。

来自 Jekyll page.rb :

def initialize(site, base, dir, name)
  @site = site
  @base = base
  @dir  = dir
  @name = name

  self.process(name)
  self.read_yaml(File.join(base, dir), name)
end

@dir 和@month 用于在准备站点生成时确定页面的相对路径。在 ArchivePage#initialize 中设置这两个属性，它将再次起作用。 (使用 1.3.1 测试)
