Question

我有postgres正在运行并且可以通过mix phoenix.new reporting连接到它，但是一个全新的凤凰应用程序。我无法完成设置，无法做ecto.create并且我能说的最好的是它没有连接到数据库......或者可能是其他一些bug ...基本上，我不知道在哪里离开这里。

$ psql -p 5432 -h localhost reporting_dev postgres
Password for user postgres:
psql (9.6.1, server 9.6.2)
Type "help" for help.

reporting_dev=#

这是我的config/dev.exs

$ grep Reporting.Repo -A 6 config/dev.exs
config :reporting, Reporting.Repo,
  adapter: Ecto.Adapters.Postgres,
  username: "postgres",
  password: "postgres",
  database: "reporting_dev",
  hostname: "localhost",
  pool_size: 10

但我无法完成ecto.create

$ mix ecto.create

could not compile dependency :phoenix_ecto, "mix compile" failed. You can recompile this dependency with "mix deps.compile phoenix_ecto", update it with "mix deps.update phoenix_ecto" or clean it with "mix deps.clean phoenix_ecto"

这是我的基本版本

你是否正在使用1.x版本的Phoenix.HTML，你应该使用2.x.

在版本1.x中，使用术语模型而不是模式，该模式在2.x和最新的Phoenix版本中使用。

Phoenix设置失败：编译错误，（KeyError）键：找不到模型
