我使用gem 'countries', require: 'iso3166'。
当我尝试启动服务器时，出现以下错误：
rake aborted!
LoadError: cannot load such file -- iso3166

我又试着跑了一次，但没用。我在网上搜索类似的问题，但没有找到任何解决办法。
知道是什么导致了这个错误吗？
最佳答案
将其添加到gemfile中并再次打包
gem 'countries', :require => 'countries/global'
iso3166模块已经添加到gem本身。您可以看到文档https://github.com/hexorx/countries
