【问题讨论】：

oops 错过了控制器位，但不管出现相同的错误。它来自 Sam Ruby 的《使用 Rails 进行敏捷 Web 开发》一书。再次对错误感到抱歉。
重新运行 bundle 以确保所有 gem 都已安装？

标签： ruby-on-rails ruby model rails-generate

【解决方案1】：

来自您的日志：

uninitialized constant Rails::Rack::Logger

这意味着有东西正在寻找 Rails::Rack:Logger 但找不到。执行以下命令查看是否安装了 Rack。

bundle show rack
/home/nrowegt/.rvm/gems/ruby-2.2.2/gems/rack-1.6.1

如果没有显示，重新运行“bundle install”或“gem install rack”
