Use the Node Package Manager to install the CDK CLI. We recommend that you install it globally using the following command:
$ npm install -g aws-cdk
To install a specific version of the CDK CLI, use the following command structure:
$ npm install -g aws-cdk@X.YY.Z
If you want to use multiple versions of the AWS CDK, consider installing a matching version of the CDK CLI in individual CDK projects. To do this, remove the -g option from the npm install command. Then, use npx aws-cdk to invoke the CDK CLI. This will run a local version if it exists. Otherwise, the globally installed version will be used.
Troubleshoot a CDK CLI installation
If you get a permission error, and have administrator access on your system, run the following:
$ sudo npm install -g aws-cdk
If you receive an error message, try uninstalling the CDK CLI by running the following:
$ npm uninstall -g aws-cdk
Then, repeat steps to reinstall the CDK CLI.
Verify a successful CDK CLI installation
Run the following command to verify a successful installation. The AWS CDK CLI should output the version number:
$ cdk --version
