我无法创建我的凤凰项目.会喜欢一些关于如何修复它的建议.

设置细节:

• Ubuntu 16.04.4 LTS
• Erlang/OTP 21 [erts-10.1] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:1] [hipe]
• Elixir 1.7.3(使用Erlang/OTP 20编译)
• 混合1.7.3(用Erlang/OTP 20编译)
• Ecto v3.0.0

我正在关注Phoenix Up and Running制作应用程序.

mix phx.new hello
cd hello
mix ecto.create

最后一个命令给了我:

 == Compilation error in file lib/hello/repo.ex ==
 ** (ArgumentError) adapter Ecto.Adapters.Postgres was not compiled, ensure it is correct and it is included as a project dependency
     lib/ecto/repo/supervisor.ex:71: Ecto.Repo.Supervisor.compile_config/2
     lib/hello/repo.ex:2: (module)
     (stdlib) erl_eval.erl:680: :erl_eval.do_apply/6
     (elixir) lib/kernel/parallel_compiler.ex:206: anonymous fn/4 in Kernel.ParallelCompiler.spawn_workers/6

我安装了postgres.我有postgres超级用户.

我正在运行 MacOS 10.14.1（MacOS 的新手），我无法运行psql通过 安装的命令brew，我收到以下错误，希望得到一些帮助：

psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

我尝试过的解决方案

1. brew services start 服务已经在运行
2. brew services stop postgresql, brew services start postgresql 还是一样的错误
3. brew remove postgres, brew install postgres, psql 还是一样的错误
4. brew unlink postgresql && brew link postgresql 还是一样的错误
5. rm -f /usr/local/var/postgres/postmaster.pid我的/usr/local/var/不包含postgres/文件夹

还有一件事要注意，当brew install postgres我收到警告时：

Warning: The post-install step …

我有一个通过 Gitlab 部署的节点应用程序。我正在使用 docker image node:12.8.0。

最近部署失败，出现以下错误
