Question

我从Ruby 1.8.7和Rails 3.0.9升级到Ruby 2和Rails 4.0.2。

刷新网页localhost：3000时发生错误。我试图删除所有布局代码applicaton.html.erb和application.rb控制器代码，以排除Ruby或Rails版本的任何更改。在控制台中，我看不到除了回溯之外的任何东西

这次崩溃发生在使用Oracle的Linux中，Mac和Postgress本地数据库也没问题。

执行Select to Oracle的sys表时出错，尤其是获取SCHEMA_MIGRATIONS表的信息

我的Gemfile：

ruby '2.0.0'
source 'https://rubygems.org'
gem 'rails', '4.0.2'
gem 'activerecord-session_store'
gem 'net-ldap'
gem "composite_primary_keys", :require =>'composite_primary_keys'
gem 'sass-rails', '~> 4.0.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'therubyracer' #, '0.11.0beta5'
gem 'libv8', '~> 3.11.8'
gem 'execjs'
gem 'jquery-rails'
gem 'rails-observers'
gem 'turbolinks'
gem 'jbuilder', '~> 1.2'
group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end
group :oracle do
  gem 'ruby-oci8'
  gem 'activerecord-oracle_enhanced-adapter'
end
gem 'debugger', group: [:development, :test]

Answer 1

解决。

我不知道到底发生了什么，但是解决方案是回到旧版本的RoR，感谢git branch和rvm，然后再次执行Bundle update和Bundle install。

升级到Rails 4和Ruby 2之后的ArgumentError（错误的参数数量（1表示0））
