我有一個Rails 3.2.8應用程序，它在我的機器上運行的很好，Postgres作爲ActiveRecord的數據庫後端。然而，當我在我的代碼部署到EC2服務器，或者通過Capistrano的或rsync'ing我的項目EC2實例，耙不再列出任何db:任務：rake數據庫任務在部署中消失
$ rake -T
rake about # List versions of all Rails frameworks and the environment
rake assets:clean # Remove compiled assets
rake assets:precompile # Compile all the assets named in config.assets.precompile
rake doc:app # Generate docs for the app -- also available doc:rails, doc:guides, doc:plugins (options: TEMPLATE=/rdoc-t...
rake load_gml # Load GML source files into the environment database
rake log:clear # Truncates all *.log files in log/ to zero bytes
rake middleware # Prints out your Rack middleware stack
rake notes # Enumerate all annotations (use notes:optimize, :fixme, :todo for focus)
rake notes:custom # Enumerate a custom annotation, specify with ANNOTATION=CUSTOM
rake rails:template # Applies the template supplied by LOCATION=(/path/to/template) or URL
rake rails:update # Update configs and some other initially generated files (or use just update:configs, update:scripts, or u...
rake routes # Print out all defined routes in match order, with names.

rake stats # Report code statistics (KLOCs, etc) from the application

rake test:recent # Run tests for {:recent=>"test:prepare"}/Test recent changes
rake test:single # Run tests for {:single=>"test:prepare"}
rake test:uncommitted # Run tests for {:uncommitted=>"test:prepare"}/Test changes since last checkin (only Subversion and Git)
rake time:zones:all # Displays all time zones, also available: time:zones:us, time:zones:local -- filter with OFFSET parameter,...
rake tmp:clear # Clear session, cache, and socket files from tmp/ (narrow w/ tmp:sessions:clear, tmp:cache:clear, tmp:sock...
rake tmp:create # Creates tmp directories for sessions, cache, sockets, and pids
rake -P還報告沒有db:任務。
我猜這是某種依賴性問題，但我不明白那是什麼，因爲我在Bundler Gemfile中聲明瞭所有的gem依賴關係。 Postgres的9.2.1安裝和工作，但即使它不是我不明白，爲什麼耙任務將消失。
任何線索，這是怎麼回事感激地接受！
你嘗試'捆綁高管耙-T'？ –
是的，對不起，我應該提到，我試過了，得到了相同的結果。 –
