Windows11环境部署本地化dify，docker compose up -d 启动后，一直报错，类似：

在windows11下部署dify报错：

db-1  | The files belonging to this database system will be owned by user "postgres".
db-1  | This user must also own the server process.

db-1  | child process exited with exit code 1
db-1  | initdb: removing contents of data directory "/var/lib/postgresql/data/pgdata"

重点就是这句：

FATAL: data directory "/var/lib/postgresql/data/pgdata" has invalid permissions

解决办法：

1. 进入dify源码的docker目录下，打开docker-compose.yaml：

找到services下的db，修改volumes，将./volumes/db/data改为postgres-data。

在docker-compose.yaml文件的最末尾的volumes下添加postgres-data:

注意，该volumes与services同级。

2. 在Docker Desktop运行的情况下，win+r打开cmd，进入dify源码的docker目录下:

执行：

docker-compose down
docker-compose up

搞定。
