Question

-----> Ruby/Rails app detected
-----> Installing dependencies using Bundler version 1.3.2
       Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin --deployment
       You are trying to install in deployment mode after changing
       your Gemfile. Run `bundle install` elsewhere and add the
       updated Gemfile.lock to version control.
       You have added to the Gemfile:
       * sqlite3 (= 1.3.5)
       * sass-rails (= 3.2.5)
       * coffee-rails (= 3.2.2)
       * uglifier (= 1.2.3)
       * jquery-rails (= 2.0.2)
       * pg (= 0.12.2)
       You have deleted from the Gemfile:
       * coffee-rails (~> 3.2.1)
       * jquery-rails
       * sass-rails (~> 3.2.3)
       * sqlite3
       * uglifier (>= 1.0.3)

正如，日志说：

  You are trying to install in deployment mode after changing
       your Gemfile. Run `bundle install` elsewhere and add the
       updated Gemfile.lock to version control.

我认为您在推送到 heroku 之前还没有提交 Gemfile.lock 文件。运行 bundle install 然后提交 Gemfile 和 Gemfile.lock。之后将代码推送到heroku。
