前提
Mem0 Restfull API
github地址：https://github.com/mem0ai/mem0/tree/main/server
介绍文档：https://docs.mem0.ai/open-source/features/rest-api
开始配置
按正常流程，我把Mem0的包上传到虚拟机之后，修改.env基础配置如下（OPENAI_API_KEY修改成自己的）：
OPENAI_API_KEY=abcPOSTGRES_HOST=postgres POSTGRES_PORT=5432 POSTGRES_DB=postgres POSTGRES_USER=postgres POSTGRES_PASSWORD=postgres POSTGRES_COLLECTION_NAME=memoriesNEO4J_URI=bolt://neo4j:7687 NEO4J_USERNAME=neo4j NEO4J_PASSWORD=mem0graph
然后修改docker-compose.yaml内容如下：
name: mem0-devservices:mem0:build:context: .. # Set context to parent directorydockerfile: mem0/dev.Dockerfileports:- "8888:8000"env_file:- .envnetworks:- mem0_networkvolumes:- ./history:/app/history # History db location. By default, it creates a history.db file on the server folder- .:/app # Server code. This allows to reload the app when the server code is updated- ../mem0:/app/packages/mem0 # Mem0 library.

执行报错
然后执行 docker compose up 命令启动，结果报错：
dependency failed to start: container mem0-dev-neo4j-1 is unhealthy
查看neo4j日志：docker-compose logs neo4j
报错内容如下：
/usr/local/lib/python3.6/site-packages/paramiko/transport.py:32: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography. The next release of cryptography will remove support for Python 3.6. from cryptography.hazmat.backends import default_backend ERROR: The Compose file './docker-compose.yaml' is invalid because: 'name' does not match any of the regexes: '^x-' You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the services key, or omit the version key and place your service definitions at the root of the file to use version 1. For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/
错误信息显示有两个问题：
1. Docker Compose 版本问题：你的 Docker Compose 版本不支持 name 字段（mem0-dev 不被支持 - 这是 Docker Compose V2 的新特性）
2. 健康检查命令还没修改：日志显示还在使用旧的 wget bolt://neo4j:8687 命令
问题修正
后面我就重新修改了docker-compose.yaml配置如下：
version: '3.8'services:mem0:build:context: .. # Set context to parent directorydockerfile: mem0/dev.Dockerfilecontainer_name: mem0-dev-mem0ports:- "8888:8000"env_file:- .envnetworks:- mem0_networkvolumes:- ./history:/app/history # History db location.

然后执行命令：
docker-compose down # 将之前启动的容器关闭并删除
docker-compose up -d # 重启容器
然后看到运行正常了：
访问Swagger页面也正常：
