我真的对 Heroku 的问题感到困惑。我是一个新手，我已经尝试了一些解决方案，但它们似乎对我没有帮助。这是我使用的错误

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

在 gem 文件中，这是我对 sqlite 3 的条目

Gem files will remain installed in /tmp/build_2i8tok6rv3gyk/vendor/bundle/ruby/2.0.0/gems/sqlite3-1.3.7 for inspection.
Results logged to /tmp/build_2i8tok6rv3gyk/vendor/bundle/ruby/2.0.0/gems/sqlite3-1.3.7/ext/sqlite3/gem_make.out
   An error occurred while installing sqlite3 (1.3.7), and Bundler cannot continue.
   Make sure that `gem install sqlite3 -v '1.3.7'` succeeds before bundling.

heroku 不支持sqlite3，请Postgresql改用。

group :development do
   gem 'sqlite3'
end

group :test, :production do
    gem 'pg'
end

这样 sqlite 将成为您的本地数据库，而 postgres 将用于测试和生产

你会想要改变你的 Gemfile

添加gem 'pg'到您的生产组

group :production do
  gem "pg"
end

然后一定要bundle install在你提交到heroku之前运行
