我正在尝试将devise安装到我的Rails应用程序中，但我得到的只是此错误消息

我曾尝试搜索，但由于操作不同，遇到许多类似的错误。对于这个问题，没有什么特别有用的。有没有比Ruby更熟练的人可以帮助我？我通常更像是一个Python家伙...

我想到可能正在使用OSX。还可能需要注意的是，这是DigitalOcean默认的Rails应用程序，该应用程序已加载了其Nginx + Rails图像。我将项目复制到服务器上的git repo中，然后将其克隆到本地计算机上。
我正在尝试将devise安装到我的Rails应用程序，但是我得到的只是此错误消息rails g devise：安装/Users/luketimothy/.rvm/gems/ruby-2.2.3/gems/debug_inspector-0.0.2 / lib / debug_inspector ....
尝试一下。
对您的红宝石和宝石进行全新安装
问题与设计无关。我发现了一个类似的问题here，该问题表示要卸载存在库不兼容问题的gem，然后重新运行捆绑软件安装。所以我做到了，而且有效！
在Gemfile中，尝试将gem 'devise'行移至下方
您是否尝试过升级devise gem的版本bundle update devise？
从头开始项目，因为在OSX下无法安装Ubuntu Rails。参见例如http://railsapps.github.io/installrubyonrails-mac.html
尝试这个=> gem update --system
