Question

Heroku声明“指定的'sqlite3'用于数据库适配器，但未加载gem。在初始提交中将gem 'sqlite3'添加到您的Gemfile”。

我已经更改了我的Gemfile，因此在开发中使用sqlite，在生产模式下使用pg。我的database.yml被添加到.gitignore文件中。有没有我需要将sqlite更改为pg的地方？

我以前跑过

bundle install --without production

我的问题的解决方案是安装生产宝石。我的生产宝石与“指定的sqlite3适配器”有什么关系，我完全不明白。

Heroku声明“为数据库适配器指定'sqlite3'”
