Question

我正在尝试编写一个函数，该函数会将命令发送到Google Cloud IoT核心中定义的设备。从控制台发送命令可以正常工作。

中的以下示例

OS_PLATFORM_VALID_END

但是，在功能日志中，我收到消息“错误：最低要求是Node.js v10.0.0。”

我在项目中运行了-v节点，结果得到v10.16.3，所以感到很困惑。谁能提供任何建议？

gcloud函数描述结果：

// const cloudRegion = 'us-central1';
// const deviceId = 'my-device';
// const commandMessage = 'message for device';
// const projectId = 'adjective-noun-123';
// const registryId = 'my-registry';
const iot = require('@google-cloud/iot');
const iotClient = new iot.v1.DeviceManagerClient({
  // optional auth parameters.
});

const formattedName = iotClient.devicePath(
  projectId,
  cloudRegion,
  registryId,
  deviceId
);
const binaryData = Buffer.from(commandMessage);
const request = {
  name: formattedName,
  binaryData: binaryData,
};

try {
  const responses = await iotClient.sendCommandToDevice(request);

  console.log('Sent command: ', responses[0]);
} catch (err) {
  console.error('Could not send command:', err);
}

package.json：
