我安装了i18n gem和插件来本地化日期，但是当我为网站服务时，我收到以下错误：
Malahovas-MacBook-Pro:test Svetlana$ rake

Liquid Exception: Object must be a Date, DateTime or Time object. "2015-12-01" given. in _includes/footer.html, included in _layouts/post.html
jekyll 2.5.3 | Error: Object must be a Date, DateTime or Time object. "2015-12-01" given.
在footer.html中，我有以下代码：
<time datetime="{{ page.date | date: "%Y-%m-%d" }}">
{{ page.date | localize: "%d %B %Y" }}
</time>
以下是插件i18n_filter.rb的代码：
require 'i18n'
LOCALE = :ru # set your locale
# Create folder "_locales" and put some locale file from
# https://github.com/svenfuchs/rails-i18n/tree/master/rails/locale
module Jekyll
module I18nFilter
# Example:
# {{ post.date | localize: "%d.%m.%Y" }}
# {{ post.date | localize: ":short" }}
def localize(input, format=nil)
load_translations
format = (format =~ /^:(\w+)/) ? $1.to_sym : format
I18n.l input, :format => format
end
def load_translations
unless I18n::backend.instance_variable_get(:@translations)
I18n.backend.load_translations Dir[File.join(File.dirname(__FILE__), '../_locales/*.yml')]
I18n.locale = LOCALE
end
end
end
end
这是一个收藏文件。使用--trace运行构建后，我得到：

你知道如何解决这个问题吗？
答案 0 :(得分：1)
I18n.localize或I18n.l需要Date，DateTime或Time参数。 page.date实际上应该是DateTime或Time类型，但我假设过滤器未加载，因此被Jekyll忽略（我在底部添加了Liquid-filter加载）。这是一个可能的解决方案：
尝试在调用I18n.localize之前解析输入字符串：
假设项目目录中的区域设置文件ru.yml位于名为./locales/的文件夹中。 i18n.rb位于./_plugins/i18n.rb
require 'date'
require 'i18n'
path = File.expand_path("../../locales/ru.yml", __FILE__)
I18n.load_path = Dir[path]
I18n.locale = :ru
module Jekyll
module I18nFilter
# Example:
# {{ post.date | localize: "%d.%m.%Y" }}
# {{ post.date | localize: ":short" }}
def localize(input, format=nil)
format = (format =~ /^:(\w+)/) ? $1.to_sym : format
if input.is_a?(String)
input = DateTime.parse(input)
end
I18n.l input, :format => format
end
def translate(key)
I18n.t key
end
end
end
# Add as a filter
Liquid::Template.register_filter(Jekyll::I18nFilter)
ru.yml可以是任何有效的yaml文件，包含语言环境，例如：
ru:
hello: приве́т
如果DateTime是格式错误的字符串，则转换为input可能会导致错误，例如空的＆＃34;＆＃34;或遗漏约会所需的东西。最小值类似于：＆＃34; 2015-01-13＆＃34;。
作为Jekyll的替代方案：查看Nanoc，它似乎更新，更容易扩展。它在Github上使用，我们将它用于localization platform PhraseApp
