这很奇怪。我在运行 rake 进行测试时遇到此错误,但在迁移时却没有。我正在运行 RVM,下面的 shell 转储应该提供您需要的任何信息。
如有任何帮助,我们将不胜感激。我见过其他一些人遇到过这个问题,但还没有适合我(或他们)的解决方案。
谢谢。

我已经升级到最新的 Rails - 3.2.6。即使我使用“bundle exec”,错误仍然存在。 (这对 3.2.6 来说并不新鲜——我仍然在 3.1 下遇到这个问题)虽然未定义的方法是新的。
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
$ bundle exec rake

我的 Gemfile,按照要求:
source 'http://rubygems.org'
gem 'rails', '3.2.6'
group :assets do
gem 'sass-rails', " ~> 3.2.5"
gem 'coffee-rails', "~> 3.2.1"
gem 'uglifier', '>= 1.2.6'
end
gem 'jquery-rails'
gem 'rake'
gem "mysql2"
gem "squeel"
gem 'tinymce-rails'
gem 'dynamic_form'
gem 'will_paginate'
gem 'devise'
gem 'whitelist'
gem 'rmagick'
gem 'json'
gem 'paperclip'
gem 'acts_as_list', :git => 'https://github.com/swanandp/acts_as_list'
gem 'htmlentities'
gem 'formtastic'
# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
# group :development, :test do
# gem 'webrat'
# end
最佳答案
gem 'rake', ">=0.9.2"# 在你的 Gemfile 中
然后
$ bundle 安装
然后
$ bundle exec 抽成
如果上述方法无效:
$ rvm all do gem install rake -v 0.9.2.2#install rake to all ruby versions
然后再次运行 rake
关于ruby-on-rails - 在任何来源中都找不到 rake-0.9.2.2,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/11627349/
