ERROR could not build the "sapcapirebook" module

[sv7en]

Hi,

In the Business Application Studio, I am trying to build a CAP simple-bookshop application.
after I run 'npm run mta-build', I get the error message:

[2024-06-26 03:31:24]  INFO executing the "npm run build:cf" command...

> book@0.0.1 build:cf
> ui5 build preload --clean-dest --config ui5-deploy.yaml --include-task=generateCachebusterInfo

sh: 1: ui5: not found

  },

repo:

branch:
change-history-1.8.0-milestone

Can any one advice, what am i doing wrong here and how to fix this?
By the way, some time ago, I was able to build normally, but this error occurred a few days ago.

Thanks in advance!

Regards,

Wenjun

Upgrading to the latest stable Node.js version fixed it for me. The older version worked with other app components, but the UI required a version >20.0.0.

@sv7en 

Have you executed 'npm install'?

Yes, I have executed 'npm install'. And then 'npm run mta-build'
