喏！又来个wget安装前的问题port更新出错。
mac 上通过docker compose up -d，安装milvus。 先下载wget 、更新macport 报错：错误日志：

(base) ➜ milvus-standalone 解析：
根据你提供的报错信息，问题出在 MacPorts 的清华源同步配置上。
问题原因
你的 MacPorts 配置尝试从 rsync://mirrors.tuna.tsinghua.edu.cn/macports/release/ports/ 同步 ports tree，但该路径在服务器上不存在，导致 rsync 报错 change_dir ... failed: No such file or directory (2)。
解决方案
你需要将 MacPorts 的源配置文件 sources.conf 中的 rsync 地址修改为正确的路径。
打开配置文件
在终端中执行以下命令，使用文本编辑器打开 sources.conf 文件：
sudo nano /opt/local/etc/macports/sources.conf
修改 rsync 地址
在文件中找到以 rsync:// 开头的行，它可能看起来像这样：
rsync://mirrors.tuna.tsinghua.edu.cn/macports/release/ports/ [default]
请将其修改为以下正确的地址：
rsync://mirrors.tuna.tsinghua.edu.cn/macports/macports-ports/ [default]
注意： 主要是将路径中的 release/ports/ 修改为 macports-ports/。
保存并退出
如果你使用的是 nano 编辑器，按 Control + O 保存，然后按 Enter 确认。
接着按 Control + X 退出编辑器。
再次尝试更新
修改完成后，再次运行更新命令：
sudo port -v selfupdate
这次应该可以成功同步 ports tree 了。
