该应用程序对Postgresql运行正常,但是当我尝试运行命令时：

heroku db:push

我得到一个令人困惑的sqlite错误,因为我的项目中没有引用sqlite：

!    Taps Load Error: cannot load such file -- sqlite3
 !    You may need to install or update the taps gem to use db commands.
 !    On most systems this will be:
 !    
 !    sudo gem install taps

这是我的database.yml文件：

development:
  adapter: postgresql
  encoding: unicode
  database: xxxx
  pool: 5
  timeout: 5000
  username: xxxx
  password: xxxx

test:
  adapter: postgresql
  encoding: unicode
  database: test
  pool: 5
  timeout: 5000
  username: xx
  password: xx

production:
  adapter: postgresql
  encoding: unicode
  database: test
  pool: 5
  timeout: 5000

我使用的是RVM,我已经创建了一个新的gemset没有任何运气.

我甚至尝试这个但是得到了相同的sqlite错误：

heroku db:push postgres://xx:xx@localhost/xx

 !    Taps Load Error: cannot load such file -- sqlite3
 !    You may need to install or update the taps gem to use db commands.
 !    On most systems this will be:
 !    
 !    sudo gem install taps

我也运行捆绑安装和捆绑更新.
