第一次無法將rails應用程序部署到heroku;忽略manifest.yml文件

Question

我想第一次將我的Rails應用程序部署到heroku上。我在Windows 8上使用Rails 3.2.11和ruby 1.9.3。我一直在尋找很長時間來回答問題，但一直沒有成功。我一直沿着heroku's tutorial開始，直到它告訴你推。

git push heroku master 

這給了我下面的錯誤：

-----> Preparing app for Rails asset pipeline

我也試着預編譯資產產生使用：

bundle exec rake assets:precompile 

這在我的公共/租入資產價值產生manifest.yml文件目錄。我已經提交了該文件。所以，根據我見過的教程，它不應該試圖預編譯這些文件。爲什麼忽略我的manifest.yml文件？

請讓我知道我能做些什麼。我想不明白。

謝謝！

Answer 1

好的，我很近。拋出Rails 3.2.x - 我現在使用4.0.x。

從Heroku的文檔：

雖然預編譯的資產，在Rails的3.x中，可以防止初始化應用程序，並通過確保下面一行在你的config/application.rb中連接到數據庫：

config.assets.initialize_on_precompile = false
