我正在使用postgresql在debian服务器上部署我的第一个railsapp。rake db:由于postgresql_adapter.rb而重置失败

的Rails 3.2.9 的Ruby 1.9.3-P327 第0.14.1

部署后,当我做了

bundle exec rake db:reset

失败与以下错误:

/var/www/opf/shared/bundle/ruby/1.9.1/gems/activerecord-3.2.9/lib/active_record/connection_adapters/postgresql_adapter.rb:1208: [BUG] Segmentation fault 

和一长串错误消息。

虽然我的database.yml的是在我的开发worksation正常工作:

为什么postgresql_adapter导致一个错误,我不能找到一个理由。

---更新

如果我把不正确的数据库名称,用户名和密码,结果是一样的。 我测试了与psql my_db my_user的数据库连接,它的工作原理。 如果我做了

bundle exec rake db:reset RAILS_ENV=production

我得到了一个错误:

undefined method `sass' for #<Rails::Application::Configuration:0x00000000dea738> 

虽然萨斯青菜护栏HAML护栏宝石出现在我的/ var/www/opf/shared/bundle/ruby​​/1.9.1/gems

====== UPDATE =======

这是我的database.yml:

development: 
    host: localhost 
    port: 5432 
    adapter: postgresql 
    encoding: utf8 
    database: mydevdb 
    pool: 5 
    username: myuser 
    password: mypass 

test: 
    host: localhost 
    port: 5432 
    adapter: postgresql 
    encoding: utf8 
    database: mytestdb 
    pool: 5 
    username: myuser 
    password: mypass 

production: 
    host: localhost

    adapter: postgresql 
    encoding: utf8 
    database: myproddb

    username: myuser 
    password: mypass 

这是我的Gemfile:

我做更多的测试,并意识到问题来自初始化过程。 在某些时候,我的应用的初始化会导致Ruby解释器崩溃。 我删除了我的config/application.rb的一些行。结果至少将崩溃更改为关于“单元化常量设计”的错误。我搜索了一下,发现我添加了在我的application.rb中添加一个“require”devise'“。所以我做了,但错误和Ruby崩溃再次来了。

该问题似乎以某种方式与资产管道和初始化相关联。 我注意到以下行让我初始化崩溃Ruby解释器,所以我评价它:

Bundler.require(*Rails.groups(:assets => %w(development test)))

Ok af在进行一些非常糟糕的研究和测试之后,我找出了问题的原因。

有几个错误:

  • 在这种execjs宝石正常工作秩序,

    gem 'therubyracer', :platforms => :ruby

必须在生产组或任何一组在外面的的Gemfile

  • 为了预编译嵌套的SASS-CSS资产(rake assets:precompile),清单(评论)必须在app/assets/stylesheets/application.css.sass的顶部被删除(我使用sass-rails和haml -rails宝石),和I had to add the line

    @import screen.css.sass

在我的应用程序/资产/样式表/ application.css.sass文件

  • 为了打捆机工作正常,我在“创业板安装捆绑”得到了一个消息添加在我的/ etc/profile文件和文件/root/.bashrc中对$PATH:服务器端。

  • 为了使capistrano deploy:update任务正常工作,不要忘记在config/deploy.rb文件中添加require 'rvm/capistrano',以便capistrano能够找到(并执行)bundle命令。

但与所有这些修正,我还是得到了同样的错误在PostgreSQL:

/var/www/opf/shared/bundle/ruby/1.9.1/gems/activerecord-3.2.9/lib/active_record/connection_adapters/postgresql_adapter.rb:1208: [BUG] Segmentation fault 

正如我为了避免存储的database.yml在github上正在使用此特殊recipe。 并使用此solution为了capistrano找到我的食谱文件。 我为这个配方构建了一个database.yml模板,但不知何故,我意识到问题来自于我的模板。

,我不得不删除每个数据库上这两条线,以轨道初始化工作正常:

host: localhost 
    port: 5432 

也许造成的database.yml是腐败的,我没有测试重新添加这些(校正)两条线。我已经花了数周时间...

---一般建议---

现在我给一些建议给开发商谁是desesparate找到解决他们的问题(像我)搜索解决方案的公平大写金额后停止。

刚刚建立与rails new newapp --database=postgresql(数据库参数使用rails new -h对于此命令的帮助)一个新的极轨基本应用程序,然后生成rails generate scaffold mymodel mycolumn一个简单的支架。

在你的应用程序目录,初始化的Git与git init和Capistrano的与capify . 然后,只需添加宝石为您的数据库(PG例如对PostgreSQL),运行捆绑安装。 然后用你自己的基本database.yml将它连接到你的数据库,让你测试看看它在你的开发工作站上的工作。 提交并推送到您的Git存储库,然后部署与capistrano并检查它在服务器端工作。

然后逐渐添加(gems,migrations和您自己的个人库)到您的newapp,直到它不起作用。

并行地将工作从newapp工作的位添加到服务器端的失败应用程序直到它工作(不要在您的开发工作站上更改应用程序上的任何内容)。

这会引导您迟早地找到解决方案。
