我对ruby编程很陌生，我正在尝试将Rails版本从4.2.8更新到5.2.1。无法确定Gemfile的正式版本。遇到错误，将不胜感激。

Bundler找不到与“ resque”宝石兼容的版本：   在Gemfile中：     resque（= 1.27.1）

resque-concurrent-restriction (= 0.5.9) was resolved to 0.5.9,which depends on
  resque (~> 1.10)

resque-mock was resolved to 0.1.1,which depends on
  resque

resque-pool (= 0.2.0) was resolved to 0.2.0,which depends on
  resque (~> 1.13)

resque-round-robin was resolved to 0.1.4,which depends on
  resque (~> 1.19)
