git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.7.2'

Answer 1

这是由 gem 提供的，rack-mini-profiler它实际上有很多用于调试 sql 查询的有用信息。如果您不想要它，只需删除该行或将其注释掉并bundle install再次运行。

# Comment out or remove line completely
# gem 'rack-mini-profiler'

在控制台/终端

bundle install

...最后不要忘记重新启动服务器。

我同意，它位于一个可怕的位置，谢天谢地，您可以使用初始化程序更改它的位置 config/initializers/
