rails gem 'countries' - LoadError: 无法加载此类文件 - iso3166

Question

I use gem 'countries', require: 'iso3166' .

When I try to start the server I got this error:

rake aborted!

LoadError: cannot load such file -- iso3166

I tried running bundle install again, but it didn't help. I searched the web for similar problem but I dind't find any solution.

Any idea about what might cause the error?

Answer 1

Add this in your gemfile and bundle it again

gem 'countries', :require => 'countries/global'

iso3166 module already added to the gem itself.

you can see documentation https://github.com/hexorx/countries

Answer 2

Countries 1.2.0 and above requires a different include than previously. Since you are locked at 1.2.5, use the new require.

gem 'countries', :require => 'countries/global'

If that is still an issue, run bundle install .
