Thank you for this issue.

Do you use ESLint with vscode?
If so, please let me know the result of the CLI.

If the CLI works, the error may be reported by Vetur.

You can try setting vetur.validation.template: false.

Thank you @ota-meshi ! I wasn't aware that Vetur was working that way (linting but non-configurable).
