进行rails部署，当我尝试推送到Heroku时，我得到了以下看似矛盾的错误，该错误都表明它搜索并找不到SQLite并且我需要安装它，并且它发现SQLite因此被拒绝推动。
我跟着Heroku's suggested steps解决了这个错误无济于事。我还尝试了仅为开发和测试环境指定SQLite的suggestion，产生相同的错误。我检查了Gemfile.lock以确保没有其他gem具有SQLite依赖项。每次更改后我捆绑，添加/提交代码到git然后尝试推送到Heroku - 我不能让这个错误改变。

Heroku运行使用PG作为DB。
在你的gem文件中，在“开发和测试做”之外添加gem PG并将SQL Gem移动到你的开发部分。
推送并提交然后部署到heroku。
部署后，执行“heroku run rake DB migrate”，这应该可以让您的数据库启动并运行。
