ruby-on-rails – 面对升级rails版本的问题

2019年8月6日 242次阅读

当我运行bundle install时,它会显示：

Fetching gem metadata from https://rubygems.org/........
Fetching additional metadata from https://rubygems.org/..
Resolving dependencies...
You have requested:
  rails = 4.2.1

The bundle currently has rails locked at 4.1.0.
Try running `bundle update rails`

然后我运行：捆绑更新rails
它给：

Fetching gem metadata from https://rubygems.org/........
Fetching additional metadata from https://rubygems.org/..
Resolving dependencies...
Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    devise (>= 0) ruby depends on
      responders (>= 0) ruby depends on
        railties (< 4.2, >= 3.2) ruby

    rails (= 4.2.1) ruby depends on
      railties (4.2.1)

请帮我解决这个问题.提前致谢.

最佳答案 看起来您正在使用旧版本的设计 – 您需要更新您的设计版本以使用Rails 4.2(捆绑更新设计).一旦设计更新到3.4.x,它就可以使用railties v4.2.1.
