Question

I tried to install the following and got the following error.

npm install @sap/cloud-sdk-op-vdm-material-stock-service

npm ERR! code CERT_HAS_EXPIRED
npm ERR! errno CERT_HAS_EXPIRED
npm ERR! request to https://npm.sap.com/@sap%2fcloud-sdk-op-vdm-material-stock-service failed, reason: certificate has expired

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\**\AppData\Local\npm-cache\_logs\2022-05-22T12_29_49_566Z-debug.log

Any common reason.

Answer 1

The error message is about the registry https://npm.sap.com/ you used.

You can run the command to switch to public npm registry:

npm config set registry http://registry.npmjs.org/

Maybe you can also check your .npmrc file and remove all registry configuration related to the https://npm.sap.com/. By default, you should then use the public registry http://registry.npmjs.org/.
