Rails 5升级，无法解决依赖关系

Question

从Rails 4.2.8升级到Rails 5.0.2会导致以下错误消息。我不确定如何解决依赖关系。红宝石版本是2.5.1。我已经能够在Rails 4.2.8上运行该应用程序和测试套件，尽管我看到较低版本的carrierwave导致打印过多，所以我希望能够对其进行升级，但它需要Rails 5

Answer 1

    sass-rails (~> 5.0.1) was resolved to 5.0.8, which depends on
      railties (>= 5.2.0)

railties 5.2将与其余的Rails 5.0冲突-您需要将sass-rails限制为< 5.0.8
