```

## Dependency Issue
`asterpy` conflicts with newer aiohttp. This service uses a standalone venv:
```bash
cd services/aster
python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
```
## Deploy to rari2
```bash
rsync -av services/aster/ rari@100.x.x.y:/home/rari/Sapphire/services/bot-aster/
ssh rari@100.x.x.y "cd ~/Sapphire/services/bot-aster && source .venv/bin/activate && pip install -r requirements.txt"
```
