我刚开始使用新的spree应用程序。
我生成了项目，安装了capistrano和其他宝石。
当我运行rake db:create（和任何其他任务）时，我得到（使用--trace）
rake aborted!

当然我正确配置了config/database.yml（我在devbox上共享同一个db用户）。
这是Gemfile：
source 'https://rubygems.org'
gem 'rails', '3.2.3'
gem 'mysql2', :groups => [:development, :test]
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'therubyracer', :platform => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
group :development do
gem 'capistrano'
end
group :production do
gem 'pg'
end
gem 'spree'
这是config/database.yml
# MySQL. Versions 4.1 and 5.0 are recommended.
#
# Install the MYSQL driver
# gem install mysql2
#
# Ensure the MySQL gem is defined in your Gemfile
# gem 'mysql2'
#
# And be sure to use new-style password hashing:
# http://dev.mysql.com/doc/refman/5.0/en/old-client.html
development:
adapter: mysql2
encoding: utf8
reconnect: false
database: project_it_development
pool: 5
username: dever
password: dever
socket: /var/run/mysqld/mysqld.sock
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: mysql2
encoding: utf8
reconnect: false
database: project_it_test
pool: 5
username: dever
password: dever
socket: /var/run/mysqld/mysqld.sock
production:
adapter: postgres
encoding: utf8
reconnect: false
database: project_it
pool: 5
username: user-production
password: pwd-user-production
socket: /var/run/mysqld/mysqld.sock
我运行bundle --without production因为我在本地机器上使用mysql而无法正确编译gem pg。
我可以使用mysql客户端的凭据登录。这可能有什么问题？
答案 0 :(得分：0)
您似乎使用的是旧版spree_core-0.40.0/lib/spree_core/find_by_param.rb:104:in
尝试在gemfile中指定它，如
gem 'spree', '1.1.0'
然后安装新版本和\或清除旧版本。
