## Prerequisites
- Python **3.10+**
- `make` (optional — you can use plain Python commands instead)
All commands below should be run from the `python/` directory:
```bash
cd python
```
## Setup
### Using Make (recommended)
All `make` targets automatically create a virtual environment (`.venv/`) and install the required dependencies — no manual setup needed.
```bash
# Install the CLI in editable mode
make install
# Install with dev tools (tests + linting)
make dev
```
### Using Python directly
```bash
python3 -m venv .venv
source .venv/bin/activate
python -m pip install -U pip
# Install in editable mode
pip install -e .
# With dev tools
pip install -e ".[dev]"
```
## Make targets
| Target | Description |
| ------------------- | ------------------------------------------------ |
| `make install` | Create venv and install the CLI (editable mode) |
| `make dev` | Create venv and install CLI + dev dependencies |
| `make test` | Run all tests (installs dev deps if needed) |
| `make lint` | Run linter and format check |
| `make format` | Auto-fix lint issues and format code |
| `make build` | Build distribution packages |
| `make clean` | Remove `dist/` |
| `make publish` | Build and publish to PyPI |
| `make publish-test` | Build and publish to Test PyPI |
| `make shell` | Open a new shell with the venv activated |
## Run tests
```bash
# Using Make
make test
# Using Python directly
pytest
# Run a specific test file
pytest tests/test_cli_integration.py
# Run a single test
pytest -k test_help
```
## Run the CLI
```bash
# Using Make — drop into an activated shell
make shell
mem0 --help
# Using Python directly (with venv activated)
source .venv/bin/activate
mem0 --help
mem0 version
# Or run without activating
.venv/bin/mem0 --help
```
## Lint
```bash
# Using Make
make lint # check only
make format # auto-fix
# Using Python directly (with venv activated)
ruff check .
ruff format .
```
## Optional extras
### OSS integration
```bash
pip install -e ".[oss]"
```
