Build errors with Vercel CLI 39.1.1

Help
1

Builds suddenly starts failing, even on redeployment of previously successful deployments. The only difference I see is that the Vercel CLI version has been upgraded to 39.1.1 in the failed deploys. Previously the successful deployments used Vercel CLI version 38.0.0.

The build gets hung up on vue-tsc --noEmit && vite build with an error that I’ve googled but without success.

Note that there were no code changes or configuration changes between the successful and failed deployments. Has anyone experienced this before?

Failed deployment on a branch (no changes) that previous deployed successfully:

Update

I tried specifying an older version of the Vercel CLI using the envirnoment variable (on the project) VERCEL_CLI_VERSION. The result was the same error. So it looks like this is not related to the Vercel CLI version.

The problem seems to be with the latest version of vue-tsc (2.1.10). I upgraded to that version and can reproduce the error locally. I still don’t know wht it means though.

Probably it’s because vue-tsc@1 does not support TypeScript 5.6.

npm create vite uses the cache stored locally regardless of a new version published on npm, it’s recommended to add @latest when using npm create (e.g. npm create vite@latest).
