Refinery - NoMethodError: undefined method `spec' for nil:NilClass

Refinery - NoMethodError: undefined method `spec' for nil:NilClass

当我安装 refinery 3.0.0 时,在捆绑过程结束时出现错误:

NoMethodError: undefined method `spec' for nil:NilClass
An error occurred while installing refinerycms-core (3.0.0), and Bundler cannot continue.

已显示。

解决方案是安装最新版本的捆绑器:

gem install bundle

希望对你有帮助
