好的，这可能是愚蠢的，但是我整夜都在努力寻找代码中此错误的原因，但是没有运气。
我的最后一个选择是看看您的眼睛是否比我的眼睛更好。
我在下面的行(第68行)中收到此错误:
<%= image_tag image_product.image.url(:medium), class: "img-responsive", id: "<%= index == 0 ? 'zoom_05' : '' %>" %>
完整的代码段如下:
<div class='carousel-inner '>
<% @product.images.each_with_index do |image_product, index| %>
<div class=<%= index == 0 ? 'item active' : '' %> >
<%= image_tag image_product.image.url(:medium), class: "img-responsive", id: "<%= index == 0 ? 'zoom_05' : '' %>" %>
</div>
<% end %>
<script>
$("#zoom_05").elevateZoom({ zoomType : "inner", cursor: "crosshair" });
</script>
</div>
<!-- sag sol -->
<a class='left carousel-control' href='#carousel-custom' data-slide='prev'>
<span class='glyphicon glyphicon-chevron-left'></span>
</a>
<a class='right carousel-control' href='#carousel-custom' data-slide='next'>
<span class='glyphicon glyphicon-chevron-right'></span>
</a>
</div>
以及完整的错误消息:

最佳答案
您不能嵌套<% %>，而需要使用字符串插值，如下所示:
<%= image_tag image_product.image.url(:medium), class: "img-responsive", id: "#{index == 0 ? 'zoom_05' : ''}" %>
尽管由于您已经在使用ruby代码，所以根本不需要任何插值，所以您可以执行以下操作:
<%= image_tag image_product.image.url(:medium), class: "img-responsive", id: index == 0 ? "zoom_05" : "" %>
