# ImportError - Missing Dependencies (/faq/import-errors)



`uv pip install agno` ships the core SDK only. Models, databases, vector stores, and interfaces load their dependencies lazily and raise an `ImportError` when the package is missing. Install the matching extra:

```bash
uv pip install -U 'agno[anthropic]'

# Extras combine
uv pip install -U 'agno[os,psycopg,sql,pgvector]'
```

Quote the extra (`'agno[...]'`) so your shell doesn't expand the brackets.

If an error names a package with no matching extra, install the package directly with the command shown in the error message.
