我无法推送到 Heroku。环顾四周，但没有找到可行的解决方案。似乎缺少一些库，gemfile 在 dev 和 test 下有 sqlite，在 production 下有 pg。下面是推送的结果和sqlite的依赖：
Fetching: sqlite3-1.3.7.gem (100%)
Building native extensions. This could take a while...
Fetching: sqlite3-ruby-1.3.3.gem (100%)

Hello! The sqlite3-ruby gem has changed it's name to just sqlite3. Rather than
installing `sqlite3-ruby`, you should install `sqlite3`. Please update your
dependencies accordingly.
Thanks from the Ruby sqlite3 team!
