编辑 - 这篇文章可能非常有用：sqlite3-ruby install error
答案 0 :(得分：59)
将此添加到您的Gemfile中，
group :production do
gem 'pg'
end
group :development, :test do
gem 'sqlite3'
end
然后做一个bundle然后重新回到heroku。你不能在Heroku上使用sqlite3 - 这是错误的原因。
答案 1 :(得分：41)
如果你从Gemfile中删除sqlite3后仍然遇到问题（或者只开发它），那么你没有在Heroku眼中重新更新该文件，因为它依赖于Git。
很简单：
git add Gemfile
git commit -m "Removed sqlite3 from Gemfile"
git push heroku master
在我意识到改变不是“正在接受”之前，我已经对这个问题嗤之以鼻，因为我没有真正将它们交给Heroku。
答案 2 :(得分：13)
经过一天尝试在众多论坛中规定的每一个修复后，这对我有用！ 首先，如果你使用Rails教程书或在线，你需要转到第二个版本（在http://ruby.railstutorial.org/在线有一个测试版）。
打开编辑器并将行添加到Gemfile：
group :production do
gem 'pg', '0.12.2'
end
group :development do
gem 'sqlite3', '1.3.4'
end
现在您还需要将新编辑的Gemfile提交给Heroku，以便接下来的步骤正确。
git add Gemfile
git commit -m "Put Sqlite3 into development in the Gemfile"
git push heroku master
答案 3 :(得分：4)
如果在应用了tibbon和animuson的指令（发生在我身上）之后仍然无法正常工作，请尝试在Gemfile中注释“gem'sqlite3”行，然后再次添加-commit-push。
答案 4 :(得分：0)
我按照这些说明进行操作，但在我的情况下，我必须将更新的Gemfile.lock文件添加到版本控制中。所以，我使用标志-a for“all”来添加Gemfile文件和Gemfile.lock文件。
git commit -am“将Sqlite3放入Gemfile中的开发中并添加更新的Gemfile.lock”
git push heroku master
答案 5 :(得分：0)
您可以使用稍微不同的语法来解决此问题：
gem 'pg', group: :production
gem 'sqlite3', group: :development
答案 6 :(得分：0)
如果你有参考：
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
在您的Gemfile中，请务必将其注释掉或将其替换为上面建议的代码。否则，如果仍然存在，您仍然会遇到同样的错误。
