我想将博客与我现有的rails应用程序集成，我使用了gemrefinerycms博客并遵循了教程https://github.com/refinery/refinerycms-blog
在迁移时，我得到了这个错误

我该如何解决这个问题，或者是否有更好的博客可用
我在github中找到了一个与您的问题匹配的链接，https://github.com/refinery/refinerycms-blog/issues/296。如前所述，他们已经解决了问题。
您的refinerycms博客的版本似乎太低，请尝试gem 'refinerycms-blog', '~> 2.1.0'或gem 'refinerycms-blog', :git => 'https://github.com/refinery/refinerycms-blog.git'获取最新版本。
希望有帮助：）
对于轨道4.1.5，打开您的Gemfile并添加：
gem 'refinerycms-blog', git: 'https://github.com/refinery/refinerycms-blog', branch: 'master'
注意：如果还安装了refinerycms页面图像扩展，请确保gem refinerygms博客位于gem"refinerycmds页面图像"之前。
