我知道,Heroku上运行耙资产:预编译任务:
-----> Writing config/database.yml to read from DATABASE_URL
-----> Preparing app for Rails asset pipeline
Running: rake assets:precompile
-----> Rails plugin injection
Injecting rails_log_stdout
Injecting rails3_serve_static_assets
-----> Discovering process types
Procfile declares types -> (none)
Default types for Ruby/Rails -> console, rake, web, worker
-----> Compiled slug size is 17.7MB
-----> Launching... done
我告诉了预编译的production.rb图片
# from: http://stackoverflow.com/questions/8052865/rails-3-1-asset-pipeline-why-my-images-do-not-precompile-for-production
config.assets.precompile += %w[*.png *.jpg *.jpeg *.gif]
那么,为什么我仍然得到这个500错误?
