RefineryCMS Engines错误:没有有效的gemspec

我无法安装任何引擎.从指南安装第一个事件引擎后,我有一个错误,说我没有有效的宝石规格.

Using refinerycms-events (1.0) from source at vendor/extensions refinerycms-events at /Users/lydia/Desktop/projects/cmsex/vendor/extensions/events did not have a valid gemspec. This prevents bundler from installing bins or native extensions, but that may not affect its functionality. The validation message from Rubygems was: authors may not be empty

现在,每当我尝试安装另一个引擎时,命令行说安装已成功,但我无法在bundle show上找到该gem.我无法生成插件和数据库.

我已将这些行添加到我的Gemfile中:

宝石'refinerycms-blog','〜> 2.1.0'

宝石'refinerycms-search','〜> 2.1.0'

这是我的宝石包含在捆绑中:

当我尝试生成插件时,我得到了这个:

$ rails generate refinery:search
Could not find generator refinery:search.

我个人认为这是因为没有有效的宝石规格.但我怎么知道哈哈.在使用博客和搜索gem编辑Gemfile后进行"$ bundle install"时,确实说它们已成功安装.但是它们没有安装,之后我什么也做不了,比如创建插件和数据库.

非常感谢你的帮助,我希望你能结束我的痛苦!
