Question

我刚刚开始使用新的rails应用，但在输入＆＃39; rails s＆＃39;后，它不能让我启动服务器。控制台只是让我解决了这个问题;

/Users/user/.rvm/gems/ruby-2.4.1/gems/railties-4.2.9/lib/rails/railtie/configuration.rb:95:in `method_missing': undefined method `load_defaults' for #<Rails::Application::Configuration:0x007fa393f7db20> (NoMethodError)
from /Users/user/Desktop/MiProyecto/Portafolio/config/application.rb:12:in `<class:Application>'
from /Users/user/Desktop/MiProyecto/Portafolio/config/application.rb:10:in `<module:Portafolio>'

from bin/rails:9:in `require'
from bin/rails:9:in `<main>'

有什么想法？提前谢谢。

ps：我已经运行了bundle install，它完全没问题。

检查启动应用程序的Rails版本。如果你有任何改变它，升级或降级它，那么，为了确保，尝试删除Gemfile.lock文件，添加＆＃34;原始＆＃34; Rails版本并再次捆绑。

我重现'method_missing': undefined method 'load_defaults'错误，首先使用5.1.3版本创建一个空白的Rails应用程序，然后将其更改为5.0.1，删除Gemfile.lock并运行bundle。

运行＆＃34; rails server＆＃34;时出现Method_missing错误
