有人用 Ruby 2.7.0
解决了这个问题吗? ?
我用过 rbenv
并安装了 Ruby v2.7.0,然后使用 Rails v6.0.2.1
创建了一个 Rails 项目.
目前,通过运行其中之一
rails s
rails s -u puma
rails s -u webrick
服务器已启动并且站点已提供服务,但在
Console
中日志我看到两条警告消息: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,警告消息是:
**.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**
最佳答案
抑制警告,如:warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call
现在,只需前缀/传递 RUBYOPT
rails 命令的环境变量:RUBYOPT='-W:no-deprecated -W:no-experimental' rails server
或者RUBYOPT='-W:no-deprecated -W:no-experimental' rails db:migrate
这可能不适用于早期版本的 ruby。
为了与早期版本的 ruby 向后兼容,在它前面加上 RUBYOPT='-W0'
反而。
例子:RUBYOPT='-W0' bundle exec rspec
如果您不想在每次运行命令时都添加前缀,那么只需将其添加到 .zshrc
的最后一行即可。或 .bashrc
(无论您使用什么):export RUBYOPT='-W:no-deprecated -W:no-experimental'
或者export RUBYOPT='-W0'
