Acabei de atualizar meu aplicativo rails para 4.2.2 e, portanto, também atualizei o gem rgeo para 0.3.20
Corri no seguinte erro:
NoMethodError: undefined method `point' for nil:NilClass

from (irb):4Então eu pesquisei na lib rgeo e notei que o gerador de fábrica em rgeo retornou nil em rgeo / geos / interface.rb
Você pode verificar no irb
2.2.1 :001 > require 'rgeo'
=> true
2.2.1 :002 > RGeo::Geos.supported?
=> false Então você quer ter certeza de que tem o GEOS lib instalado. Eu resolvi isso via brew brew install geos e instalei o rgeo novamente e finalmente funcionou
