# DaytonaSandbox 集成

> 使用 LangChain Python 与 DaytonaSandbox 沙箱后端进行集成。

[Daytona](https://daytona.io) 提供快速启动的沙箱环境，支持多语言。有关注册、认证和平台详情，请参阅 [Daytona 文档](https://www.daytona.io/docs)。

## 安装

<CodeGroup>
  ```bash pip theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
  pip install langchain-daytona
  ```

  ```bash uv theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
  uv add langchain-daytona
  ```
</CodeGroup>

## 创建沙箱后端

在 Python 中，您使用提供商 SDK 创建沙箱，然后将其封装到 [deepagents 后端](/oss/python/deepagents/backends) 中。

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
from daytona import Daytona

from langchain_daytona import DaytonaSandbox

sandbox = Daytona().create()
backend = DaytonaSandbox(sandbox=sandbox)

result = backend.execute("echo hello")
print(result.output)
```

## 与 Deep Agents 配合使用

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
from daytona import Daytona
from langchain_anthropic import ChatAnthropic

from deepagents import create_deep_agent
from langchain_daytona import DaytonaSandbox

sandbox = Daytona().create()
backend = DaytonaSandbox(sandbox=sandbox)

agent = create_deep_agent(
    model=ChatAnthropic(model="claude-sonnet-4-20250514"),
    system_prompt="You are a coding assistant with sandbox access.",
    backend=backend,
)

result = agent.invoke(
    {
        "messages": [
            {"role": "user", "content": "Create a hello world Python script and run it"}
        ]
    }
)
```

## 清理

您负责通过 Daytona SDK 管理沙箱的生命周期。完成后，请停止或销毁沙箱。
