export const SandboxConfigHint = () => {
  if (typeof document === "undefined") {
    return null;

    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>;

};

我们可以将文件从沙箱内下载到本地。

  const sandbox = await Sandbox.create()

  // 在沙箱内创建一个文件用于测试
  const filePathInSandbox = '/tmp/test-file'
  await sandbox.files.write(filePathInSandbox, "test-file-content")

  // 从沙箱读取文件内容
  const content = await sandbox.files.read(filePathInSandbox)

  // 将文件写入本地文件系统
  const localFilePath = './local-test-file'
  fs.writeFileSync(localFilePath, content)

  await sandbox.kill()
  ```

    file.write(content)
