我正在尝试通过 aws-iot-sdk-js-v2 连接到 AWS IoT Core,并在运行PubSub 示例时收到以下错误,如下所述:

/home/pi/aws-iot-device-sdk-js-v2/node_modules/aws-crt/dist/native/binding.js:60
    throw new Error("AWS CRT binary not present in any of the following locations:\n\t" + search_paths.join('\n\t'));
    ^

Error: AWS CRT binary not present in any of the following locations:
        /home/pi/aws-iot-device-sdk-js-v2/node_modules/aws-crt/dist/bin/native/aws-crt-nodejs

我有一个树莓派 3B+

  • aws-iot-device-sdk-v2:1.5.2
  • aws-crt:1.8.1

我在这里尝试了aws-iot-device-sdk-js-v2 #119的解决方案,但没有任何帮助。

我按照AWS IoT 中的描述按照onnecting-to-existing-device进行操作,但仍然会发生此错误。

在尝试按以下顺序安装和更新后,我运行的命令(删除所有是我的 raspi 上的服务后的顺序) :

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install cmake
sudo apt-get install libssl-dev
sudo apt-get install -y nodejs
restarted by sudo shutdown -r 0
cd ~
npm install aws-crt
npm install aws-iot-device-sdk-v2
cd ~
git clone https://github.com/aws/aws-iot-device-sdk-js-v2.git
cd ~/aws-iot-device-sdk-js-v2
npm install
cd ~
mkdir certs
(I copied the certs and changed the name accordingly...)
cd ~/aws-iot-device-sdk-js-v2/samples/node/pub_sub
npm install
node dist/index.js --topic topic_1 --root-ca ~/certs/Amazon-root-CA-1.pem --cert ~/certs/device.pem.crt --key ~/certs/private.pem.key --endpoint <endpoint>
 (I swap the <endpoint> with my own....)

顺便说一下 aws-iot-device-sdk-python-v2 的 工作原理,但我更喜欢使用 node.js SDK ...

我在 aws-iot-device-sdk-js-v2 上打开了一个新问题,但我仍在等待答案。

请帮忙。

我在jmklix 的 aws-iot-device-sdk-js-v2 存储库收到了解决我的问题的答案:

目前,包的维护者不包括树莓派的预编译二进制文件,但如果我们愿意,我们可以手动执行此操作。在aws-crt-nodejs中描述:

git clone https://github.com/awslabs/aws-crt-nodejs.git
cd aws-crt-nodejs
git submodule update --init
npm install

然后我们需要将 aws-crt-nodejs.node 复制到错误信息中提到的位置:

cp -r ~/aws-crt-nodejs/dist/bin/linux-arm ~/aws-iot-device-sdk-js-v2/node_modules/aws-crt/dist/bin/linux-arm

解决了我的问题。
