URI 中未初始化的类变量 @@schemes

Question

我正在尝试迁移架构，但是当我执行此操作时，会显示以下日志：

$ rails db:migrate
rails aborted!
NameError: uninitialized class variable @@schemes in URI
Did you mean?  scheme_list
D:/Projects/lms-2021/config/application.rb:3:in `require'
D:/Projects/lms-2021/config/application.rb:3:in `<top (required)>'
D:/Projects/lms-2021/Rakefile:4:in `require_relative'
D:/Projects/lms-2021/Rakefile:4:in `<top (required)>'
bin/rails:9:in `require'
bin/rails:9:in `<main>'
(See full trace by running task with --trace)

如何解决这个问题？

• Windows 10 专业版
• git bash 终端
• 轨道 v 5.1.7
• 红宝石 v 3.1.2

根据此评论，安装或更新 gem 'globalid' 对我有用。

添加gem 'globalid', '~> 1.0'然后运行bundle install。
