Install with Docker ​

Use default MetaGPT image ​

# Step 1: Download metagpt official image and prepare config2.yaml
docker pull metagpt/metagpt:latest
mkdir -p /opt/metagpt/{config,workspace}
docker run --rm metagpt/metagpt:latest cat /app/metagpt/config/config2.yaml > /opt/metagpt/config/config2.yaml
vim /opt/metagpt/config/config2.yaml # Change the config

# Step 2: Run metagpt demo with container
docker run --rm \
    --privileged \
    -v /opt/metagpt/config/config2.yaml:/app/metagpt/config/config2.yaml \
    -v /opt/metagpt/workspace:/app/metagpt/workspace \
    metagpt/metagpt:latest \
    metagpt "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/config2.yaml:/app/metagpt/config/config2.yaml \
    -v /opt/metagpt/workspace:/app/metagpt/workspace \
    metagpt/metagpt:latest

docker exec -it metagpt /bin/bash
$ metagpt "Write a cli snake game"

# Step 1: Download metagpt official image and prepare config2.yaml
docker pull metagpt/metagpt:latest
mkdir -p /opt/metagpt/{config,workspace}
docker run --rm metagpt/metagpt:latest cat /app/metagpt/config/config2.yaml > /opt/metagpt/config/config2.yaml
vim /opt/metagpt/config/config2.yaml # Change the config

# Step 2: Run metagpt demo with container
docker run --rm \
    --privileged \
    -v /opt/metagpt/config/config2.yaml:/app/metagpt/config/config2.yaml \
    -v /opt/metagpt/workspace:/app/metagpt/workspace \
    metagpt/metagpt:latest \
    metagpt "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/config2.yaml:/app/metagpt/config/config2.yaml \
    -v /opt/metagpt/workspace:/app/metagpt/workspace \
    metagpt/metagpt:latest

docker exec -it metagpt /bin/bash
$ metagpt "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 configure file /opt/metagpt/config/config2.yaml to container /app/metagpt/config/config2.yaml
• Map host directory /opt/metagpt/workspace to container /app/metagpt/workspace
• Execute the demo command metagpt "Write a cli snake game"

Build image by yourself ​

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

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

Installation for full features ​

This is relevant if you want to generate diagrams such as quadrant chart, system designs, sequence flow, etc. They are provided as intermediate results if you run the software startup example.

Mermaid ​

Mermaid is a language that uses text to generate flowcharts, pie charts, Gantt charts, and other diagrams. MetaGPT uses Mermaid to create flowcharts, sequence diagrams, Gantt charts, etc. Mermaid is implemented in Node.js, and direct installation can be somewhat costly. MetaGPT provides the following Mermaid Engines to convert Mermaid text into diagrams:

nodejs Install mermaid-cli directly through nodejs. MetaGPT calls the command line to turn Mermaid text into diagrams. You need to install nodejs first, then use npm to install:

npm install -g @mermaid-js/mermaid-cli

npm install -g @mermaid-js/mermaid-cli

The official method provided by mermaid, installed via nodejs, thus it basically supports all platforms and also supports output in png/svg/pdf formats. However, it requires the installation of nodejs and mermaid-cli, which comes with certain costs for installation and use, and also requires a browser environment at runtime.

pyppeteer Mermaid can also be called via JavaScript, and pyppeteer is a web automation testing tool implemented in Python that can execute JavaScript scripts. Therefore, using pyppeteer + mermaidjs can convert Mermaid text into diagrams. You can install pyppeteer with pip:

pip install pyppeteer

pip install pyppeteer

This method is relatively simple to install, has no platform restrictions, and supports output in png/svg/pdf formats. However, it requires a dependency on a browser, so you need to install a browser first and set the browser path when running:

export PUPPETEER_EXECUTABLE_PATH=/path/to/your/chromium  # or edge or chrome

export PUPPETEER_EXECUTABLE_PATH=/path/to/your/chromium  # or edge or chrome

(Note: pyppeteer is no longer maintained)

playwright As pyppeteer is no longer maintained, it recommends using playwright-python as a replacement. The principle of running mermaid with playwright is the same as with pyppeteer. However, playwright-python requires the installation of its own provided browser and cannot use an already installed browser. The official only supports the following platforms:

• Windows 10+, Windows Server 2016+ or Windows Subsystem for Linux (WSL).
• MacOS 12 Monterey or MacOS 13 Ventura.
• Debian 11, Debian 12, Ubuntu 20.04 or Ubuntu 22.04.

pip install playwright
playwright install --with-deps chromium

pip install playwright
playwright install --with-deps chromium

ink The mermaid.ink project provides the function to convert Mermaid text into diagrams online, refer to https://mermaid.ink/. Thus, any internet-connected device can use ink method without the need for a local browser or other dependencies. However, this method only supports generating png and svg, not pdf, and requires access to https://mermaid.ink/ during operation, so it may be affected by the network and other factors, possibly impacting stability.
