Gem :: LoadError:为数据库适配器指定了"sqlite3"，但未加载gem [英] Gem::LoadError: Specified 'sqlite3' for database adapter, but the gem is not loaded

问题描述

我正在尝试将我的应用程序推送到heroku，但收到此消息.

I'm trying to push my app to heroku but am getting this message.

Gem::LoadError: Specified 'sqlite3' for database adaptor, but the gem is not loaded.

但是我没有.我的database.yml文件中的任何地方都没有sqlite3

But I did not. I don't have sqlite3 anywhere in my database.yml file

development:
  adapter: postgresql
  encoding: unicode
  database: blog_development
  pool: 5
  timeout: 5000
  host:  localhost

test:
  adapter: postgresql
  database: blog_test
  pool: 5
  timeout: 5000

production:
  adapter: postgresql
  database: blog_production
  pool: 5
  timeout: 5000

我的适配器名称是psotgresql.我什至自己打开了文件

My adapter name is psotgresql. I even opened the file myself

cat database.yml

我搜索了文件，但是找不到postgresql.这是我的宝石文件

I searched through the file but could not find postgresql. Here is my gemfile

ruby '2.1.0'
gem 'rails', '4.1.1'

group :development, :test do
  gem 'pg', '0.17.1'
  gem 'rspec-rails', '3.0.1'
end

group :production do
  gem 'pg', '0.17.1'
  gem 'rails_12factor'
end

group :test do
  gem 'selenium-webdriver', '2.35.1'
  gem 'capybara', '2.1.0'
end

gem 'sass-rails', '~> 4.0.2'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'sprockets-rails', '~> 2.1.3'
gem 'bootstrap-sass', '3.1.1.1'

gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.1.1'

group :doc do

  gem 'sdoc', require: false
end

gem 'bcrypt', '~> 3.1.7'

我在这里的生产环境中有pg.我已经多次运行捆绑包安装，捆绑包更新，git add，git commit和git push heroku master，但我仍然收到此消息.

I have pg located in the production environment here. I have ran bundle install, bundle update, git add, git commit, and git push heroku master numerous times and I still get this message.

我不明白这一点.我没有为数据库适配器指定sqlite3.

I don't understand this. I did NOT specify sqlite3 for my database adaptor.

我不知所措.

推荐答案

我必须将sqlite3版本指定为1.3.13:

I had to specify my sqlite3 version as 1.3.13:

gem 'sqlite3', '~> 1.3.13'

然后运行bundle update.
