错误原因:

错误是由 hexo-related-popular-posts 引发,在该库源码中使用 moment 初始化 list.date 导致了错误。 list.date 通过打印值可以看到是一个 moment 对象,但这个 moment 对象并不规范或者说可能在某处修改了这个 moment 对象的值。

moment 内部初始化有一段逻辑是:

1
this._d = new Date(config._d != null ? config._d.getTime() : NaN);

这个 config 就是 moment(list.date) 传入的 list.date 的值。config._d 是一个时间类型的字符串,并不是 Date 类型,因此没有 getTime 的方法。

解决方案:

  • 方法1:

    • theme/next/_config.yml 中的 related_posts.params.isDate 设为 false,推荐列表中不展示时间
  • 方法2:修改源码

    • 打开文件\node_modules\hexo-related-popular-posts\lib\list-json.js

    • 修改代码

      1
      2
      3
      if (inOptions.isDate && list.date != '') {
      ret.date = moment(list.date).format(config.date_format || 'YYYY-MM-DD')
      }

      } catch(ex) {
      ret.date = moment(list.date._d).format(config.date_format || 'YYYY-MM-DD')
      }
      }
