Mix task “release” not found error
问题 I was setting up an Ubuntu 16.04 server for my Elixir/Phoenix application with edeliver when edeliver failed with the error message ** (Mix) The task "release" could not be found along with a exit code of 1. If I go to my build server, git pull my app and run MIX_ENV=prod mix release or just mix release after getting dependencies, I get the same error. However, the same application works without any problem locally. My erlang version is erts-9.0 and elixir version is 1.5.5 on both the server
