Ruby on rails 在轨道上安装装置2.3.5

我正在rails 2.3.5、ruby 1.8.7-p302上工作，我正在尝试安装Desive，因此我在Gemfile中添加了gem“Desive”，然后捆绑安装工作正常，然后我尝试编写脚本/生成Desive:install，但失败了，我不知道原因

您可能需要更改Desive版本，因为它来自主分支

尝试：

---

gem'designe'，'1.0.7'

我为什么要使用这个版本？我可以使用文档中相同的说明吗？脚本/生成设备：安装找不到“设备：安装”生成器MOSTAFA，当前的说明适用于Rails 3/4及更高版本。为了将它用于Rails2.3.x，您需要选择一个早期的分支。快速研究表明1.0.7适用于Rails 2.3。因此，您可能需要寻找相关说明。：）可能重复的
