# 流式输出结果

export const SandboxConfigHint = () => {
  if (typeof document === "undefined") {
    return null;
  } else {
    return <Note>在运行本文档中的示例代码前，请确保您已正确配置环境变量，详情请参考 <a href="/sandbox/get-start#配置环境变量">配置环境变量</a>。</Note>;
  }
};

<SandboxConfigHint />

要在命令执行时流式输出结果，请在 JavaScript 中向 `commands.run()` 方法传递 `onStdout`、`onStderr` 回调，或在 Python 中向 `commands.run()` 方法传递 `on_stdout`、`on_stderr` 回调。
