Macbook M1 - Postgres 安装 - “/tmp/.s.PGSQL.5432” - 执行时失败；`/bin/launchctl 引导程序

Question

我刚买了一台新的 Macbook Pro M1，并一直在尝试使用自制软件安装 Postgres。在尝试了一系列不同的方法（从安装不同版本的 Postgres 到尝试）后，rm /usr/local/var/postgres/postmaster.pid我没有运气。我现在甚至无法在没有错误消息的情况下成功安装 Postgres。当我卸载然后重新安装时，brew install postgres我得到：

\n

然后如果我运行brew services start postgres我会得到：

\n

\xe2\x9e\x9c  ~ brew services start postgres\nBootstrap failed: 5: Input/output error\nTry re-running the command as root for richer errors.\nError: Failure while executing; `/bin/launchctl bootstrap gui/501 /Users/landonlapensee/Library/LaunchAgents/homebrew.mxcl.postgresql.plist` exited with 5\n

\n

如果我运行psql我会得到：

\n

Error: Failure while executing; `/bin/launchctl bootstrap gui/501 /Users/landonlapensee/Library/LaunchAgents/homebrew.mxcl.postgresql.plist` exited with 5.\n\xe2\x9e\x9c  ~ psql\npsql: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory\n    Is the server running locally and accepting connections on that socket?\n

\n

如果我运行 \xe2\x9e\x9c ~ rm /usr/local/var/postgres/postmaster.pid我得到：

\n

rm: /usr/local/var/postgres/postmaster.pid: No such file or directory\n

\n

我在这个问题上很迷茫。我正在尝试将其设置为用于 ruby​​ on Rails 环境。有谁知道可能导致此问题的原因是什么？（我尝试了很多不同的线程/命令，我认为我创建了导致冲突的根文件）

\n

或者有人有任何付费服务的建议可以帮助我解决这个问题吗？

十分感谢！

我有同样的问题。显然，重新安装后并没有启动服务器，因为还有另一台服务器 postgresql@13（更新前的先前版本）仍在运行。我杀死了该进程，然后它启动了更新的服务器。
