You can run the node-v command to check the version of Node.js.

Install the SDK

We recommend that you use npm to install dependent modules for Node.js. For more information, visit npm. All Alibaba Cloud SDKs for Node.js are stored in the @alicloud directory.

For example, MPS SDK for Node.js is downloaded to the /path/to/aliyun-openapi-Node.js-sdk directory. If you develop an application based on the SDK core library, run the following command to install the @alicloud/pop-core module: The following sample code provides an example:
```
npm install @alicloud/pop-core --save
```
The --save option in the preceding command writes the module to the package.json file of the application as a dependent module.

Update the SDK

If new features are unavailable in the current SDK, update the SDK to the latest version. The following sample code provides an example:

npm install @alicloud/pop-core --save
