ruby-on-rails-3 - how can I resolve this gemfile conflict

Question

I'm getting this error after bundle install. How can I fix it?

 Bundler could not find compatible versions for gem "excon":
  In Gemfile:
    locomotive-heroku (~> 0.0.2) ruby depends on
      excon (~> 0.9.4) ruby

    excon (0.20.0)

Answer 1

我通过放置机车/引擎和机车/heroku的当前存储库的位置来修复它。即 gem 'locomotive-heroku', git: 'repolocation', require: 'locomotive/heroku' 这也是最终让我在 heroku 上安装 locomotivecms 的原因。我确实需要将其设置为在生产环境中编译资产。

Answer 2

卸载最新版本的 gem gem uninstall excon -v=0.20.0：. 然后再次捆绑安装以查看它是否解决了问题。
