我正在关注Hartl的ROR教程，我正在努力让我的数据库在Heroku上工作，但无济于事。当我运行以下命令时：
heroku run rake db:create
或
heroku run rake db:migrate
我收到以下错误：
Running `rake db:create` attached to terminal... up, run.5477
/usr/bin/env: ruby2.2: No such file or directory
Running `rake db:migrate` attached to terminal... up, run.5562
/usr/bin/env: ruby2.2: No such file or directory
我正在postgresql和development使用production。这是我最近的提交https://github.com/Euklidian-Space/sample-app
以下是heroku日志：

在bin/bundle，bin/rake，bin/rails和bin/setup个文件中，每个文件的第一行都会显示#!/usr/bin/env ruby2.2。将它们全部更改为#!/usr/bin/env ruby。然后再尝试部署。
