这是因为 MySQL 的 sql_mode 设置了 only_full_group_by，导致在 GROUP BY 子句中未包含的列不能在 SELECT 子句中使用。可以尝试以下两种处理方式：

1. 修改 sql_mode
将 MySQL 的 sql_mode 修改为不包含 only_full_group_by 这个选项，可以在 MySQL 配置文件 my.cnf 或者 my.ini 中找到 sql_mode 选项，将其修改为：

sql_mode=NO_ENGINE_SUBSTITUTION

然后重启 MySQL 服务即可生效。

2. 修改查询语句
在 SELECT 子句中将非聚合列 p.p_id 改为聚合列，例如使用 MAX(p.p_id)。修改后的查询语句如下：

SELECT DISTINCT MAX(p.p_id) AS p_id, p.project_name, p.project_code, p.project_nature, u1.id AS directorId, CASE WHEN up1.member_type = 348 THEN u1.nickname ELSE up1.member_name END AS directorName 
FROM project p 
LEFT JOIN userproject up1 ON p.p_id=up1.p_id AND up1.director=1 
LEFT JOIN sys_user u1 ON up1.member_id = u1.id 
LEFT JOIN userproject up ON p.p_id=up.p_id 
LEFT JOIN sys_user u ON up.member_id = u.id 
LEFT JOIN sys_user_department d ON d.user_id = u.id 
WHERE (p.enable = ? AND p.audit_status = ? AND p.organization_id = ? AND p.project_name IS NOT NULL) 
GROUP BY p.project_name,p.project_code,p.project_nature 
ORDER BY p.p_id DESC
