Ruby on Rails Rakefile错误

Question

当我把我的ruby on rails应用推送到heroku时，所有的图片都没有加载。

我试图预编译所有的资源，但是我得到了这个错误：

jack:my_first_ruby_app Jack$ bundle exec rake assets:precompile
rake aborted!

Rakefile的内容：

/usr/bin/env rake
# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.

require File.expand_path('../config/application', __FILE__)

MyFirstRubyApp::Application.load_tasks

Ruby 2.0.0p195的版本

请编辑您的Rakefile

并注释了第1行

像这样

#!/usr/bin/env rake
