我正在开发一个简单的rails Web应用程序，当我尝试运行时，它运行得很好
rails console
得到了这个错误：
2020-08-03 17:30:51 -0600: Rack app error handling request { GET /microposts }

我正在运行ruby 2.7.0和rails 6.0.3.2，现在如果我尝试运行：
rails server
我也犯了同样的错误。我试过评论春季宝石以及运行春季停止，但都无济于事。我是不是错过了一些显而易见的东西？我觉得奇怪的是，在它工作和不工作之间唯一改变的是尝试运行rails console。
这是我的Gemfile
source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }
ruby '2.7.1'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

end
如有任何帮助或建议，我们将不胜感激！
附言：如果有什么不同的话，我会在10号窗户上调整这个rubymine的内部。
更新：
我已经尝试从我的gem文件中完全删除sqlite，但仍然收到同样的错误。然后我检查了我的Gemfile.lock文件中的依赖项，但没有找到。为什么我会出现此错误？
