MetaGPT( The Multi-Agent Framework)：颠覆AI开发的革命性多智能体元编程框架

news2024/10/6 3:30:50

一个多智能体元编程框架，给定一行需求，它可以返回产品文档、架构设计、任务列表和代码。这个项目提供了一种创新的方式来管理和执行项目，将需求转化为具体的文档和任务列表，使项目管理变得高效而智能。对于需要进行规划和协调的项目，这个框架提供了强大的支持.

例如，如果你输入’ python startup.py ’ ’ Design a RecSys like今日头条’ '，你会得到很多输出，其中之一是data & api Design

生成一个分析和设计示例的成本约为0.2美元(在GPT-4 API费用中)，而生成一个完整项目的成本约为2.0美元。

1.安装

1.1 安装视频指南

Matthew Berman: How To Install MetaGPT - Build A Startup With One Prompt!!

常规安装

#Step 1: Ensure that NPM is installed on your system. Then install mermaid-js. (If you don't have npm in your computer, please go to the Node.js offical website to install Node.js https://nodejs.org/ and then you will have npm tool in your computer.)
npm --version
sudo npm install -g @mermaid-js/mermaid-cli

#Step 2: Ensure that Python 3.9+ is installed on your system. You can check this by using:
python --version

#Step 3: Clone the repository to your local machine, and install it.
git clone https://github.com/geekan/metagpt
cd metagpt
pip install -e.

Note:

If already have Chrome, Chromium, or MS Edge installed, you can skip downloading Chromium by setting the environment variable
PUPPETEER_SKIP_CHROMIUM_DOWNLOAD to true.
Some people are having issues installing this tool globally. Installing it locally is an alternative solution,
```
npm install @mermaid-js/mermaid-cli
```

don’t forget to the configuration for mmdc in config.yml

PUPPETEER_CONFIG: "./config/puppeteer-config.json"
MMDC: "./node_modules/.bin/mmdc"

if pip install -e. fails with error [Errno 13] Permission denied: '/usr/local/lib/python3.11/dist-packages/test-easy-install-13129.write-test', try instead running pip install -e. --user
将Mermaid图表转换为SVG、PNG和PDF格式。除了Node.js版本的mermaid - cli之外，你现在还可以选择使用Python版本的剧作家、pyppeteer或mermaid。
- Playwright
  - Install Playwright
```
pip install playwright
```
  - Install the Required Browsers
  to support PDF conversion, please install Chrominum.
```
playwright install --with-deps chromium
```
  - modify config.yaml
  uncomment MERMAID_ENGINE from config.yaml and change it to playwright
```
MERMAID_ENGINE: playwright
```
- pyppeteer
  - Install pyppeteer
```
pip install pyppeteer
```
  - Use your own Browsers
  pyppeteer alow you use installed browsers, please set the following envirment
```
export PUPPETEER_EXECUTABLE_PATH = /path/to/your/chromium or edge or chrome
```
  please do not use this command to install browser, it is too old
```
pyppeteer-install
```
  - modify config.yaml
  uncomment MERMAID_ENGINE from config.yaml and change it to pyppeteer
```
MERMAID_ENGINE: pyppeteer
```
- mermaid.ink
  - modify config.yaml
  uncomment MERMAID_ENGINE from config.yaml and change it to ink
```
MERMAID_ENGINE: ink
```
  Note: this method does not support pdf export.

1.2 Docker安装指南

#Step 1: Download metagpt official image and prepare config.yaml
docker pull metagpt/metagpt:latest
mkdir -p /opt/metagpt/{config,workspace}
docker run --rm metagpt/metagpt:latest cat /app/metagpt/config/config.yaml > /opt/metagpt/config/key.yaml
vim /opt/metagpt/config/key.yaml # Change the config

#Step 2: Run metagpt demo with container
docker run --rm \
    --privileged \
    -v /opt/metagpt/config/key.yaml:/app/metagpt/config/key.yaml \
    -v /opt/metagpt/workspace:/app/metagpt/workspace \
    metagpt/metagpt:latest \
    python startup.py "Write a cli snake game"

#You can also start a container and execute commands in it
docker run --name metagpt -d \
    --privileged \
    -v /opt/metagpt/config/key.yaml:/app/metagpt/config/key.yaml \
    -v /opt/metagpt/workspace:/app/metagpt/workspace \
    metagpt/metagpt:latest

docker exec -it metagpt /bin/bash
$ python startup.py "Write a cli snake game"

The command docker run ... do the following things:

Run in privileged mode to have permission to run the browser
Map host directory /opt/metagpt/config to container directory /app/metagpt/config
Map host directory /opt/metagpt/workspace to container directory /app/metagpt/workspace
Execute the demo command python startup.py "Write a cli snake game"

1.3 构造自定义

#You can also build metagpt image by yourself.
git clone https://github.com/geekan/MetaGPT.git
cd MetaGPT && docker build -t metagpt:custom .

1.4 相关配置

Configure your OPENAI_API_KEY in any of config/key.yaml / config/config.yaml / env
Priority order: config/key.yaml > config/config.yaml > env

#Copy the configuration file and make the necessary modifications.
cp config/config.yaml config/key.yaml

Variable Name	config/key.yaml	env
OPENAI_API_KEY # Replace with your own key	OPENAI_API_KEY: “sk-…”	export OPENAI_API_KEY=“sk-…”
OPENAI_API_BASE # Optional	OPENAI_API_BASE: “https://<YOUR_SITE>/v1”	export OPENAI_API_BASE=“https://<YOUR_SITE>/v1”

#Run the script
python startup.py "Write a cli snake game"
#Do not hire an engineer to implement the project
python startup.py "Write a cli snake game" --implement False
#Hire an engineer and perform code reviews
python startup.py "Write a cli snake game" --code_review True

After running the script, you can find your new project in the workspace/ directory.

Preference of Platform or Tool

You can tell which platform or tool you want to use when stating your requirements.
