【问题描述】：

我真的不认为有语法问题，我认为这可能是版本问题，不过，你们觉得这是什么样的？请注意，这只发生在生产环境中。我正在使用乘客（因为它是 Rails 3，我不喜欢在生产中使用 beta gem）：

宝石版本：1.8.23 导轨版本：3.2.11 Ruby 版本：1.9.3p374（我升级它认为它会有所帮助，我之前认为是 1.8.7）

【问题讨论】：

哦，这是第 11 行周围的区域： def index @product_properties = @product.product_properties.ransack(params[:q]).result + .page(params[:page]).per (params[:per_page]) respond_with(@product_properties) end
我们需要查看您的代码（点击“编辑”将其添加到您的问题中）。

标签： ruby-on-rails ruby passenger

【解决方案1】：

看起来您使用的是 Ruby 1.8（基于路径中的 /usr/lib/ruby/gems/1.8/），但 render :text => { exception: exception.message }.to_json 中的哈希语法仅适用于 Ruby 1.9。

在 Ruby 1.9 中，您可以说：h = {key: 1} 在 Ruby 1.8 中，您必须使用 h = {:key => 1}

【讨论】：

嗯，做到了。谢谢！

【解决方案2】：

任性的“.”在这个开头

.page(params[:page]).per(params[:per_page])

排队

@product_properties = @product.product_properties.ransack(params[:q]).result + .page(params[:page]).per(params[:per_page])

就像它在错误消息开头所说的那样。

【讨论】：

这就是我害怕的。显然，正如错误消息所述，这是一个语法错误——但是，对于我没有使用的 Ruby 版本，这是一个语法错误吗？
我不这么认为。我很确定这通常是 Ruby 语言中的语法错误，与哪个版本无关。
