Heroku的抱怨sqlite3的后，我已经卸载它

Question

我试图推到Heroku的，我最初得到一个错误信息，如：

Detected sqlite3 gem which is not supported on Heroku. 
!  https://devcenter.heroku.com/articles/sqlite3 

所以我换成Heroku的sqlite3的，现在它仍抱怨同样的错误信息

有人能帮我

这是我的Gemfile和Gemfile.lock的

source 'https://rubygems.org' 

gem 'rails', '3.2.13' 
gem 'pg' 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 
    gem 'uglifier', '>= 1.0.3' 
end 
gem 'jquery-rails' 
gem 'backbone-on-rails' 

Gemfile.lock的

而且我的继承人的database.yml

development: 
    adapter: postgresql 
    encoding: unicode 
    database: poster_development 
    host: localhost 

# Warning: The database defined as "test" will be erased and 
# re-generated from your development database when you run "rake". 
# Do not set this db to the same as development or production. 
test: 
    adapter: postgresql 
    encoding: unicode 
    database: poster_test 
    host: localhost 

production: 
    adapter: postgresql 
    encoding: unicode 
    database: poster_production 

Answer 1

是在sqlite3宝石production组的Gemfile的？

如果你在本地开发sqlite3，那么你可能想在你的Gemfile这样的东西。

group :production do 
    gem 'pg' 
end   

group :development, :test do 
    gem 'sqlite3' 
end 

不要忘了运行bundle install
