我正在运行bundle install时收到以下这些消息
Your Gemfile lists the gem sqlite3 (= 1.3.5) more than once. You should probably keep only one of them. While it's not a problem now,it could cause errors if you change the version of just one of them later. Your Gemfile lists the gem rspec-rails (= 2.10.0) more than once. You should probably keep only one of them. While it's not a problem now,it could cause errors if you change the version of just one of them later. Your Gemfile lists the gem pg (= 0.12.2) more than once. You should probably keep only one of them. While it's not a problem now,it could cause errors if you change the version of just one of them later. 我在Heroku中使用Postgresql,我相信我在开发和测试中都使用Postgresql.我最近从sqlite迁移/切换到postgresql. 我是否还需要sqlite3 gems:development或in:development,:test? 最后,开发与发展是否有区别? :开发,:测试? database.yml的 development: adapter: postgresql encoding: unicode database: xxxxxx_development pool: 5 username: xxxxxx password: test: adapter: postgresql encoding: unicode database: xxxxxx_development pool: 5 username: xxxxxx password: 的Gemfile gem 'rails','3.2.11' gem "bootstrap-sass" gem 'will_paginate' gem 'bootstrap-will_paginate','0.0.6' gem 'pg','0.12.2' gem 'pg_search' group :development,:test do gem 'sqlite3','1.3.5' gem 'rspec-rails','2.10.0' gem 'guard-rspec','0.5.5' end group :development do gem 'sqlite3','2.10.0' end # Test gems on Macintosh OS X group :test do gem 'rspec-rails','2.10.0' end group :production do gem 'pg','0.12.2' gem 'rack-google_analytics' end 解决方法
您正在重复在此处的开发组中添加sqlite:
group :development,'2.10.0' end 你可以在这里删除你的第二个开发组列表,因为它没有添加任何东西 – 你已经在第一个语句中将它们放入开发和测试中.类似地,通过将??pg放在任何组之外,它可以在所有组中使用,因此将其添加到生产中是一个重复的列表. 重写你的gemfile可能是: gem 'rails','0.0.6' # gem 'pg','2.10.0' end group :test do gem 'guard-rspec','0.5.5' end group :production do gem 'pg','0.12.2' gem 'rack-google_analytics' end 另外,一个感受到痛苦的人的一个友好提示:尝试在开发中使用相同的db作为生产.我知道最初在本地设置postgres可能会很棘手,但是一旦它在那里它就会坚如磐石并且非常容易使用.由于PG和SQLite实现之间的差异(例如,在字段iirc中搜索文本),您将面临更少的错误风险. 没有sqlite: gem 'rails',:test do gem 'rspec-rails','0.5.5' end group :production do gem 'rack-google_analytics' end (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
