当前行为
我正在部署一个具有以下结构的伞式项目：
- apps/
-- app_web <--- Phoenix app
-- app <--- Ecto app
运行时mix edeliver start production出现错误，但应用程序成功启动：
-----> starting production servers
production node:
user : user
host : server-1
path : /home/user/apps/app/app_release
response: ▸ Received 'pang' from app@127.0.0.1!
▸ Possible reasons for this include:
▸ - The cookie is mismatched between us and the target node
▸ - We cannot establish a remote connection to the node

START DONE!
此外，在尝试获取生产中的迁移状态时出现以下错误mix edeliver show migrations on production：
-----> migrations in production servers
production node:
user : app
host : server-1
path : /home/user/apps/app/app_release
response: ▸ Given the following expression: Elixir.Edeliver.run_command([:list_pending_migrations, "app", ""])

预期行为
我希望应用程序在发生错误时不会启动，并在调用命令时显示迁移状态。
