Cross DB Ecto配置失败

Question

在config/dev.exs：

config :drupex, Drupex.Repo,
  adapter: Ecto.Adapters.Postgres,
  -- username, password, database, hostname, pool_size omitted --

config :drupex, Drupex.DrupalRepo,
  adapter: Ecto.Adapters.Mysql,
  -- username, password, database, hostname omitted --

在mix.exs下的defp deps do下，我在{:mariaex, "~> 0.8.2"},之后添加了{:postgrex, ">= 0.0.0"}。最后在lib/drupex/repo.ex我添加了

defmodule Drupex.DrupalRepo do
  use Ecto.Repo, otp_app: :drupex
end

我跑了mix deps.get，mix deps.compile现在正在运行mix我得

** (ArgumentError) adapter Ecto.Adapters.Mysql was not compiled, ensure it is correct and it is included as a project dependency

Answer 1

证明适配器名为MySQL，并且区分大小写。更改为adapter: Ecto.Adapters.MySQL,解决了问题。
