我很难将我最新的 rails 3.2 应用程序推送到 heroku。我之前一直在推动它，没有任何问题，自上次工作提交以来我所做的最近的事情是为 postgres 和几个模型添加了一个 hstore 列。这些都可以在我和其他计算机上完美运行。
正在运行
heroku run rake db:migrate 我得到以下输出：
james@James-PC:~/tendersave$ heroku run rake db:migrate
Running `rake db:migrate` attached to terminal... up, run.1
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. See the release notes for more on this: http://weblog.rubyonrails.org/2012/1/4/rails-3-2-0-rc2-has-been-released. (called from <top (required)> at /app/Rakefile:7)

注意最后一行的错误
同样在运行 heroku run db:setup 我得到这个：
james@James-PC:~/tendersave$ heroku run rake db:setup
Running `rake db:setup` attached to terminal... up, run.1

d36q1tfb51f169 already exists
sh: psql: not found
再次在最后一行出现错误的地方。
然后，如果我检查 heroku 的日志，我会得到以下信息（我想是因为它没有运行迁移）：
