我有一个使用ruby-2.3.1的ruby应用程序，它在Gemfile中提到。
但是当我们将应用程序推送到heroku时，它总是最终使用ruby-2.2.4。我已经尝试了所有可能的解决方案，例如更新捆绑器和所有，但没有成功;它仍然使用ruby-2.2.4。我们还重述了dynos。
我们缺少任何有线步骤？
的Gemfile：
source 'https://rubygems.org'
# if there is a super emergency and rubygems is playing up, try
#source 'http://production.cf.rubygems.org'
ruby '2.3.1'
def rails_master?
ENV["RAILS_MASTER"] == '1'
end
if rails_master?

# Rails 5 is going to ship with Action Cable, we have no use for it as
# we already ship MessageBus, AC introduces dependencies on Event Machine,
# Celluloid and Faye Web Sockets.
#
# Note this means upgrading Rails is more annoying, to do so, comment out the
# explicit dependencies, and add gem 'rails', bundle update rails and then
# comment back the explicit dependencies. Leaving this in a comment till we
