Ruby on rails heroku运行rake db:迁移失败

我正在尝试将我的postgresql数据库迁移到Heroku上。当我运行heroku run rake db:migrate失败时，我收到以下错误：

Running `rake db:migrate` attached to terminal... up, run.4898                                                       
/usr/bin/env: ruby1.9.1: No such file or directory

当我运行heroku运行ruby-v时：

Running `ruby -v` attached to terminal... up, run.9649                                                               
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]

这是我的档案：

感谢您抽出时间阅读此代码。

您可以改用此代码

heroku run:detached rake db:migrate

它会起作用的。 确保在运行最终代码之前添加、提交和推送

直接转到项目所在的位置

$ git add .
$ git commit -m "heroku repo"
$ git push heroku master

然后运行最后的代码

heroku run:detached rake db:migrate
