Hex dependency resolution failed while installing Pigeon

Hey Guys,

I needed a library to send notifications using FCM, most famous elxiir library I got is pigeon

I’m using the latest version - {:pigeon, “~> 2.0.0-rc.1”}

I’m getting following error-

Resolving Hex dependencies...
#Incompatibility<#Term<your app>, cause: {:conflict, #Incompatibility<#Term<pigeon >= 1.1.5>, cause: {:conflict, #Incompatibility<#Term<pigeon >= 1.1.5>, #Term<not httpoison ~> 0.7 or ~> 1.0>, cause: :dependency>, #Incompatibility<#Term<your app>, #Term<not httpoison ~> 2.0>, cause: :dependency>}>, #Incompatibility<#Term<your app>, #Term<not pigeon ~> 2.0.0-rc.1>, cause: :dependency>}>
Resolution completed in 0.417s
Because pigeon >= 1.1.5 depends on httpoison ~> 0.7 or ~> 1.0 and your app depends on httpoison ~> 2.0, pigeon >= 1.1.5 is forbidden.
So, because your app depends on pigeon ~> 2.0.0-rc.1, version solving failed.
