Rails 5.1 and Geocoder: SSL_connect returned=1 errno=0 state=error: certificate verify failed

Rails 5.1 and Geocoder: SSL_connect returned=1 errno=0 state=error: certificate verify failed

我正在使用 Geocoder 获取地址的坐标:

location.rb

geocoded_by :address      
after_validation :geocode

由于 OpsenSSL 错误,它没有保存

OpenSSL::SSL::SSLError (SSL_connect returned=1 errno=0 state=error: certificate
verify failed):

我使用 Nominatim 作为 API。我错过了什么吗?

更新

这是 bundle install 输出的摘录

Using geocoder 1.5.0

Bundle complete! 22 Gemfile dependencies, 82 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.

问题已通过

解决
gem update --system
