heroku运行rake db：migrate：没有这样的文件或目录

我是Rails的新手，我想将我的第一个Rails应用程序上传到Heroku。

我已经在Heroku中安装了我的应用程序，但是当我尝试创建数据库时出现此错误：

vagrant@rails-forge:~/apps/betsman$ heroku run rake db:migrate --app betsman
Running `rake db:migrate` attached to terminal... up, run.3809
: No such file or directory

但这真的什么也没告诉我。所以我检查了Heroku日志，并得到以下错误：

：没有这样的文件或目录00:00 app [web.1]：/ usr / bin / env：ruby

这是我的Gemfile：

ruby '2.1.0'

gem 'pg'
gem 'rails', '4.1.1'
gem 'sass-rails', '~> 4.0.3'
#gem 'sass-rails', github: 'rails/sass-rails', branch: :master

end

group :production do

end

我在Rails 4.1.1中使用Ruby 2.1.0 任何帮助都将受到欢迎。如果您需要其他物品，请告诉我。

谢谢！

编辑：

我找到了解决方案。显然，我必须使用以下命令来更新位于bin文件夹中的文件：

rake rails:update:bin
