merb - `load_dependency'：Gem:Module 的未定义方法 `activate' (NoMethodError)

Question

b-core-1.0.13/lib/merb-core/core_ext/kernel.rb:142:in load_dependency': undefined methodactivate' for Gem:Module (NoMethodError) from /home/subrahmanyam/.rvm/gems/ruby-1.8.7-p374 @mostfit/gems/merb-core-1.0.13/lib/merb-core/bootloader.rb:405:in load_dependencies' from /home/subrahmanyam/.rvm/gems/ruby-1.8.7-p374@mostfit/gems/merb-core-1.0.13/lib/merb-core/bootloader.rb:405:ineach' 来自 /home/subrahmanyam/.rvm/gems/ruby-1.8.7-p374@mostfit/gems /merb-core-1.0.13/lib/merb-core/bootloader.rb:405:in load_dependencies' from /home/subrahmanyam/.rvm/gems/ruby-1.8.7-p374@mostfit/gems/merb-core-1.0.13/lib/merb-core/bootloader.rb:393:inrun'

在我更新 ruby​​gems 之前，Merb 运行良好。现在它显示上述错误。请帮我。

提前致谢

我认为这个问题是由于使用了旧版本的 merb 应用程序。由于不再支持 merb 应用程序，您可以尝试将 gem 列表更新为旧版本。

你可以试试这个命令：sudo gem update --system <version number>

尝试在<version number>.

希望这可以帮助。
