Vagrant启动失败求助：Laravel Homestead配置报错排查

问题描述 #

我是Laravel Homestead新手，已安装VirtualBox和Vagrant，按步骤配置后启动Vagrant时出现以下错误：

Traceback (most recent call last):

请问问题出在哪里？

问题原因 #

错误提示明确指向YAML语法解析失败，核心问题在services节点的格式：你给enabled添加了列表项前缀-，但Homestead的services配置是对象结构，enabled和disabled是对象下的键，而非列表元素。这种错误导致YAML解析器无法识别合法的键值对格式。

修复方法 #

修改Homestead.yaml中的services部分，去掉enabled前面的-，并保持缩进一致：

services:
    enabled:
        - "mysql"
#    disabled:
#        - "postgresql@11-main"

如果需要启用多个服务，直接在enabled的列表中添加即可，例如：

services:
    enabled:
        - "mysql"
        - "nginx"

额外注意事项 #

你的sites节点存在重复的map: cmsmy-pro.dev.local配置，虽然不会引发当前的语法错误，但后续可能导致站点路由冲突，建议清理重复条目。
