有人解决过这个问题Ruby 2.7.0
吗?
我使用rbenv
并安装了Ruby v2.7.0,然后使用创建了一个Rails项目Rails v6.0.2.1
。
目前,通过运行
rails s
rails s -u puma
rails s -u webrick
服务器启动并为站点提供服务,但是在Console
日志中,我看到两个警告消息:
local:~/rcode/rb27$ rails s
=> Booting Puma
=> Rails 6.0.2.1 application starting in development
=> Run `rails server --help` for more startup options
.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/gems/actionpack-6.0.2.1/lib/action_dispatch/middleware/stack.rb:37: warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call
.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/gems/actionpack-6.0.2.1/lib/action_dispatch/middleware/static.rb:110: warning: The called method `initialize' is defined here
Puma starting in single mode...
* Version 4.3.1 (ruby 2.7.0-p0), codename: Mysterious Traveller
* Min threads: 5, max threads: 5
* Environment: development
* Listening on tcp://127.0.0.1:3000
* Listening on tcp://[::1]:3000
因此,警告消息为:
**.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/gems/actionpack-6.0.2.1/lib/action_dispatch/middleware/stack.rb:37: warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call**
