SAP CAP Typescript - Error - Could not find a declaration file for module '@sap/cds'

[sandeepmalhotra]

Hello Everyone 

I am using typescript with CAP

After upgrading to new version, I start getting following error

Could not find a declaration file for module '@sap/cds'. '/project/node_modules/@sap/cds/lib/index.js' implicitly has an 'any' type.
Try `npm i --save-dev @types/sap__cds` if it exists or add a new declaration (.d.ts) file containing `declare module '@sap/cds';`ts(7016)

for statement

import cds from "@sap/cds";

Hi @sandeepmalhotra ,

the types have moved to the cap-js/cds-types package. So just install it via `npm i -D @cap-js/cds-types` and there you have all your types in one .d.ts file.

With Version 0.8.0 this error occurs again. So i reverted back to 0.6.5

I've encountered the problem also for cds-8.6.0. I spent some time to analyze it and what helped me was to add the following script to package.json file: "postinstall": "test -L node_modules/@types/sap__cds || ln -s ../@cap-js/cds-types node_modules/@types/sap__cds" (works on linux/macos systems)

This seems to be a known issue.  For me, running npm rebuild resolved it.  See https://cap.cloud.sap/docs/get-started/troubleshooting#typescript.

Type definitions for @SAP/cds not found or incomplete​

  Explanation

Root Cause 1	The package @cap-js/cds-typer is not installed.
Solution 1	Install the package as a dev dependency.
Root Cause 2	Symlink is missing.
Solution 2	Try npm rebuild or add @cap-js/cds-types in your tsconfig.json.

Do you use cds-ts to run commands? Otherwise, try the reply from @brian_keenan here: https://community.sap.com/t5/technology-q-a/facing-error-while-building-and-watching-cap-project/qaq...
