当我在创建新应用程序之后运行Rails服务器,然后生成任何东西时,我得到以下信息:
$ rails server
Booting Puma
Rails 5.2.2 application starting in development
Run `rails server -h` for more startup options
Exiting
NameError: undefined method `h2_connection' for class `#<Class:0x708f018e>'
alias_method at org/jruby/RubyModule.java:2843
有人可以帮忙吗
