MetaGPT aims to simplify and automate the software development process by providing high-quality and relevant outputs.

Getting Started 🚀

Installation

# Step 1: Ensure that NPM is installed on your system. Then install mermaid-js.
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
python setup.py install

Docker Installation 🐋

# Step 1: Download metagpt official image and prepare config.yaml
docker pull metagpt/metagpt:v0.1
mkdir -p /opt/metagpt/config && docker run --rm metagpt/metagpt:v0.1 cat /app/metagpt/config/config.yaml > /opt/metagpt/config/config.yaml
vim /opt/metagpt/config/config.yaml # Change the config

# Step 2: Run metagpt image
docker run --name metagpt -d \
    -v /opt/metagpt/config:/app/metagpt/config \
    -v /opt/metagpt/workspace:/app/metagpt/workspace \
    metagpt/metagpt:v0.1

# Step 3: Access the metagpt container
docker exec -it metagpt /bin/bash

# Step 4: Play in the container
cd /app/metagpt
python startup.py "Write a cli snake game"

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

Start the Metagpt container with the default command tail -f /dev/null
Map host directory /opt/metagtp/config to the container directory /app/metagpt/config
Map host directory /opt/metagpt/workspace to the container directory /app/metagpt/workspace

Build an image by yourself

# You can also build metagpt image by yourself.
cd metagpt && docker build --network host -t metagpt:v0.1 .

Configuration

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"
