〇、解决方案
升级homebrew，命令如下：
bash
brew update-reset一、问题现象
通过命令brew install redis安装Redis，异常如下：
bash
fatal: not in a git directory
Warning: No remote 'origin' in /opt/homebrew/Library/Taps/homebrew/homebrew-services, skipping update!
Warning: You are using macOS 14.
We do not provide support for this pre-release version.
It is expected behaviour that some formulae will fail to build in this pre-release version.
It is expected behaviour that Homebrew will be buggy and slow.
Do not create any issues about this on Homebrew's GitHub repositories.
Do not create any issues even if you think this message is unrelated.
Any opened issues will be immediately closed without response.
Do not ask for help from MacHomebrew on Twitter.
You may ask for help in Homebrew's discussions but are unlikely to receive a response.

brew services start redis
Or, if you don't want/need a background service you can just run:

三、启动服务
接下来就要启动Redis服务，并登录客户端，测试简单实用。
使用redis-server命令启动Redis服务。启动结果如下：
bash
18066:C 10 Oct 2023 16:14:48.320 * oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
18066:C 10 Oct 2023 16:14:48.320 * Redis version=7.2.1, bits=64, commit=00000000, modified=0, pid=18066, just started
18066:C 10 Oct 2023 16:14:48.320 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf

通过redis-cli -p 6379（或redis-cli）登录客户端，测试结果：
bash
127.0.0.1:6379> hset office id 16 name finance
(integer) 2
127.0.0.1:6379> hget office
(error) ERR wrong number of arguments for 'hget' command
127.0.0.1:6379> hget office id
"16"
127.0.0.1:6379> hget office name
"finance"
127.0.0.1:6379> set a 'bbb'
OK
127.0.0.1:6379> get a
"bbb"通过info命令查看Redis信息，结果为：
