传递性宝石无法正确解析

Question

Bundler could not find compatible versions for gem "activemodel":
  In Gemfile:
    rails (= 5.1.6.1) was resolved to 5.1.6.1, which depends on
      activemodel (= 5.1.6.1)

    web-console (~> 3.7.0) was resolved to 3.7.0, which depends on
      activemodel (>= 5.0)

activemodel的可传递web-console是否应解析为5.1.6.1？也许我对如何解决这些宝石感到困惑。

无论这些应该兼容。
