python --versionin your terminal. Download and install Python from https://www.python.org/downloads/ if needed. - Node.js and npm: These are required for some Metagpt functionalities. Install them together from https://nodejs.org/en/download/package-manager. Verify the installation with
npm -v.
Installation Steps:
1. Create a Virtual Environment (Recommended):
A virtual environment helps isolate project dependencies. Here’s how to create one using venv (Python 3.3+) or virtualenv (older versions):
python -m venv metaGPT # Using venv
# OR
virtualenv metaGPT # Using virtualenvActivate the environment:
source metaGPT/bin/activate # Linux/macOS
# OR
metaGPT\Scripts\activate.bat # Windows2. Clone the Metagpt Repository:
Open your terminal and use git to clone the repository:
git clone https://github.com/geekan/MetaGPT.git3. Install Dependencies:
Navigate to the cloned directory:
cd MetaGPTInstall Python dependencies using pip:
pip install -r requirements.txtNext, install additional dependencies using setup.py:
python setup.py install4. Install Mermaid (Optional):
Mermaid is for generating diagrams within Metagpt, but it’s optional. Install it with:
npm install mermaid-js mermaid-cli- Locate the line
# OpenAI API key(around line 10) and remove the#symbol to uncomment it. - Paste your copied OpenAI API key after the colon (
:). - Optional: If you have access to a specific OpenAI model (e.g., gpt4), uncomment the line
# modeland set it to the corresponding model name (e.g.,model: gpt4). - Save the
config.yamlfile.
5. Obtain an OpenAI API Key:
It utilizes OpenAI’s API for text generation. Head to https://platform.openai.com/ and create an account if you don’t have one.
Navigate to the "API Keys" section and create a new secret key. Name it something relevant, like "metagpt_key". Copy the generated key, you’ll need it later.
6. Configure:
Open the config.yaml file within the metagpt/config directory. You can use a text editor like Visual Studio Code.
- Locate the line
# OpenAI API key(around line 10) and remove the#symbol to uncomment it. - Paste your copied OpenAI API key after the colon (
:). - Optional: If you have access to a specific OpenAI model (e.g., gpt4), uncomment the line
# modeland set it to the corresponding model name (e.g.,model: gpt4). - Save the
config.yamlfile.
Running Metagpt:
Now you’re ready to run it!
- Activate your virtual environment (if you created one).
- Start Metagpt using the
startup.pyscript:
python startup.pyThis will launch Metagpt, and you should see a prompt like metagpt>. Now you can interact with it by giving it prompts to generate code or perform other tasks.
Important Notes:
- Remember to keep your OpenAI API key secure.
- Metagpt is under active development, so refer to the official documentation for any potential updates to the installation process.

Creating a Snake Game with Metagpt
Prompt:
Create a simple 2D snake game in Python. The snake should move around a grid, eating apples to grow longer. The game ends when the snake collides with itself or the wall.
Expected Response:
Metagpt would generate a Python script that includes:
Python
import pygame
import random
# Constants
WIDTH = 600
HEIGHT = 600
SNAKE_SIZE = 10
APPLE_SIZE = 10
FPS = 10
# Colors
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)
# Game class
class Game:
def __init__(self):
pygame.init()
self.screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Snake Game")
self.clock = pygame.time.Clock()
self.snake = [(WIDTH // 2, HEIGHT // 2)]
self.direction = 'right'
self.apple = self.generate_apple()
def generate_apple(self):
while True:
x = random.randint(0, WIDTH - SNAKE_SIZE) // SNAKE_SIZE * SNAKE_SIZE
y = random.randint(0, HEIGHT - SNAKE_SIZE) // SNAKE_SIZE * SNAKE_SIZE
if (x, y) not in self.snake:
return x, y
def draw(self):
self.screen.fill(BLACK)
pygame.draw.rect(self.screen, WHITE, (self.snake[0][0], self.snake[0][1], SNAKE_SIZE, SNAKE_SIZE))
pygame.draw.rect(self.screen, RED, (self.apple[0], self.apple[1], APPLE_SIZE, APPLE_SIZE))
pygame.display.update()
def move(self):
x, y = self.snake[0]
if self.direction == 'right':
x += SNAKE_SIZE
elif self.direction == 'left':
x -= SNAKE_SIZE
elif self.direction == 'up':
y -= SNAKE_SIZE
elif self.direction == 'down':
y += SNAKE_SIZE
self.snake.insert(0, (x, y))
def check_collision(self):
if self.snake[0] in self.snake[1:]:
return True
if self.snake[0][0] < 0 or self.snake[0][0] >= WIDTH or self.snake[0][1] < 0 or self.snake[0][1] >= HEIGHT:
return True
return False
def check_apple(self):
if self.snake[0] == self.apple:
self.apple = self.generate_apple()
return True
return False
def run(self):
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_RIGHT and self.direction != 'left':
self.direction = 'right'
elif event.key == pygame.K_LEFT and self.direction != 'right':
self.direction = 'left'
elif event.key == pygame.K_UP and self.direction != 'down':
self.direction = 'up'
elif event.key == pygame.K_DOWN and self.direction != 'up':
self.direction = 'down'
self.move()
if self.check_collision():
running = False
if self.check_apple():
self.snake.append((self.snake[-1][0], self.snake[-1][1]))
self.draw()
self.clock.tick(FPS)
if __name__ == "__main__":
game = Game()
game.run()
This code provides a basic framework for a snake game, including game initialization, snake movement, apple generation, collision detection, and rendering. You can further customize it by adding features like a score system, power-ups, or different game modes.
