本地调试Dify源代码（非Docker）

参考自如下官方文档：https://docs.dify.ai/en/getting-started/install-self-hosted/start-the-frontend-docker-container

---

调试步骤

1. 启动中间件Docker服务

先执行下面的命令：

cd workspace-python

git clone https://github.com/langgenius/dify.git



cd ${dify}/docker

cp middleware.env.example middleware.env



# 可以给 docker-compose.middleware.yaml 文件中的服务增加一个名称，便于标识

vi docker-compose.middleware.yaml

最终，docker-compose.middleware.yaml的内容如下：

name: dify

services:
  # The postgres database.

    image: postgres:15-alpine

    env_file:
