问题描述
我正在尝试在Rails 6.0.3.2项目上安装Active Admin。我正在遵循本指南（https://activeadmin.info/0-installation.html）。第一个命令rails g active_admin:install产生以下错误：
rails g active_admin:install --use_webpacker
invoke devise
generate No need to install devise,already done.
Deprecation warning: Expected boolean default value for '--orm'; got :active_record (string).
This will be rejected in the future unless you explicitly pass the options `check_default_type: false` or call `allow_incompatible_default_type!` in your code
You can silence deprecations warning by setting the environment variable THOR_SILENCE_DEPRECATION.

在config/initializers/active_admin.rb中，我尝试注释掉第7行config.site_title = "My Site's Title"。这样做然后运行rails g active_admin:install --use_webpacker或rails db:migrate都会产生以下错误：
