Git Push Heroku Master - 失败？

Question

所以我尝试将此应用推送到 heroku：

https://github.com/harrystech/prelaunchr    

我在 ubuntu 中使用 virtualbox。

我使用这个安装了 ruby​​：

$ sudo apt-get install curl   # Required
$ curl -L get.rvm.io | bash -s stable   # Get RVM
$ source ~/.bashrc   # Reboot the shell
$ rvm requirements   # To get the command below
$ sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-   core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion  # Install Libraries
$ rvm install 1.9.3   # Install ruby v1.9.3
$ rvm use 1.9.3
$ gem install rails   # Install rails (I had to run this command twice. Error trying to find railties the first time.. weird)    

但是，当我创建我的 heroku 应用程序并尝试将应用程序推送到它时，它给了我这个错误：

对于我安装了 postgresql 的数据库（虽然不知道它是否有任何相关性）

假设 git push heroku 确实推送到 heroku（git remote -v 会确认），错误消息是：

   Running: rake assets:precompile
   DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed in Rails 4.0. Move them out and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb.
   rake aborted!
   refer/cream-tooltip@2x.png isn't precompiled

你可以在“Ruby on Rails Rake assets:precompile error”和this issue找到一些建议：

打开config/environments/production.rb 并确保以下选项设置为true：

# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = true
config.serve_static_assets = true

然后运行：

rake assets:precompile --trace RAILS_ENV=production
