升级到Rails 3.1之后,尝试运行Rails服务器后出现以下错误:

/usr/local/rvm/gems/ruby-1.9.2-p180/gems/activesupport-3.1.0/lib/active_support/whiny_nil.rb:48:in `method_missing': undefined method `context_class' for nil:NilClass (NoMethodError)


也有很多其他的失败,但是我不想全部粘贴。这是我的gemfile:

source 'http://rubygems.org'

gem 'rails', '3.1.0'
gem 'activeadmin'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3', '1.3.4'
gem 'gravatar_image_tag', '0.1.0'
gem 'will_paginate', '3.0.pre2'
gem 'meta_search'
gem 'sass-rails'

group :development do
gem 'rspec-rails', '2.0.1'
gem 'annotate-models', '1.0.4'
gem 'ruby-debug19', :require => 'ruby-debug'
end

group :test do
gem 'rspec', '2.0.1'
gem 'webrat', '0.7.1'
gem 'autotest-fsevent', '0.2.4'
gem 'autotest-growl', '0.2.9'
gem 'autotest', '4.3.2'
gem 'autotest-rails-pure', '4.1.0'
gem 'spork', '0.8.4'
gem 'factory_girl_rails', '1.0'
end


这是其余的错误:

我能做什么 ?

最佳答案

尝试运行rake rails:update。询问时将其覆盖,然后查看更改并确保保留要保留的文件(因此最后,您将保留它们和您的更改的合并结果)。

这就是我所做的,它修复了与您类似的错误。
