未定义的方法`define_index‘with sphinx sphinx

Question

当我运行rake ts:index或rake ts:configure时得到这个错误。我记不住我尝试过的所有东西--我找到的大多数解决方案都与旧版本的gem有关，等等。显然，这不是我的define_index定义，我把它放在了索引文件夹中，这是最新的想法-sphinx自述文件。

Thinking的3.0.0版本之前就已经在使用define_index方法了。现在，索引定义使用ThinkingSphinx::Index.define方法，并且驻留在app/indices/文件夹中，而不是模型文件。实际上，您已经有了新样式的定义，所以只需从item.rb中删除define_index代码块即可。
