Phoenix 1.0 to 1.2: Unchecked dependencies for environment dev

elixir, phoenix-framework

Solution

The issue was somewhere in the cache on my machine.

I ran `mix deps.clean --all` and it fixed the issue.

Problem

I am updating Phoenix from 1.0 to 1.2 I followed the steps to upgrade from 1.0 to 1.1 and then 1.1.x to 1.2.0 Whenever I try to compile I am getting the following error: ``` Unchecked dependencies for environment dev: * phoenix_pubsub_redis (Hex package) the dependency does not match the requirement "~> 2.1", got "1.0.0" * phoenix_html (Hex package) the dependency does not match the requirement "~> 2.6", got "2.2.0" * phoenix (Hex package) the dependency does not match the requirement "~> 1.2.0", got "1.0.3" * phoenix_ecto (Hex package) the dependency does not match the requirement "~> 3.0-rc", got "1.2.0" ** (Mix) Can't continue due to errors on dependencies ``` Does anyone know what is going on or how this could be fixed?
