方法一：使用淘宝镜像

直接运行下面的命令即可：

SASS_BINARY_SITE=https://npm.taobao.org/mirrors/node-sass/ npm install node-sass
我们可能更希望能直接使用 npm install 安装所有依赖，所以我的做法是在项目内添加一个 .npmrc 文件：

sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
phantomjs_cdnurl=https://npm.taobao.org/mirrors/phantomjs/

```ruby
# remove attr and replace node
doc = Nokogiri::HTML::DocumentFragment.parse(self.description)
imgs = doc.search("img")
imgs.each do |img|
  style = img.attr("style")
  puts style.inspect
  img.replace("<amp-img height='100' width='610' layout='responsive' src='#{img.attr("src")}' ></amp-img>")
end
doc.css('*').remove_attr('style')

# Query with preload and join

```elixir
q = from l in List,
          join: ul in UserList,
          where: ul.user_id == ^current_user.id and l.id == ul.list_id,
          order_by: [desc: l.done_at, asc: l.id]
    lists = q |> preload(:user) |> Repo.all
    
```
