Can't deploy - error TS2307: Cannot find module 'aws-cdk-lib' or its corresponding type declarations.

I'm trying to follow the README.md instructions to deploy he sagemaker-jumpstart-model project. The command cdk deploy fails raising the exception below:

XPS-15-9570:~/generative-ai-cdk-constructs-samples/samples/sagemaker_jumpstart_model$ cdk deploy

All the prerequisites are satisfied, as shown below:

$ node --version
v18.20.0
$ cdk version
2.134.0 (build 265d769)
$ jq --version
jq-1.6

What did I miss here ?

Kind regards,

Nicolas

Hi @nicolasduminil , thank you for reporting this issue. What is the output of npm i?

[scottschreckengaust]

Hello @ nicolasduminil, sorry for the inconvenience. The npm install step was missing from the README.md. The pull request, #49, has that update.

[nicolasduminil]

Hello, Many thanks for the update. Here is the new exception raised while running cdk deploy command:

$ cdk bootstrap aws://49.../eu-west-3

The error seems to state that the environment hasn't been bootstrapped, but it was. What might be wrong again here ? I can see that, despite of having correctly configured my region as being eu-west-3, it tries to use us-east-1.

Many thanks in advance.

Hi @nicolasduminil , did you update the region in samples/sagemaker_jumpstart_model/bin/sagemaker_jumpstart_model.ts ?
