I had errors when I did below commands.

1. git clone https://github.com/coreui/coreui-free-bootstrap-admin-template.git xxx
2. cd xxx
3. npm install
4. npm start

The error messages were below.

Error: Can't find stylesheet to import.
╷
2 │ @import "@coreui/coreui/scss/functions";
│ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
╵
src/scss/examples.scss 2:9 root stylesheet

Error: Can't find stylesheet to import.
╷
8 │ @import "@coreui/coreui/scss/coreui";
│ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
╵
src/scss/style.scss 8:9 root stylesheet

The return of ls -l node_modules/\@coreui/coreui was below.
node_modules/@coreui/coreui -> ../../../../@coreui/coreui

So I did npm install @coreui/coreui, the errors are disappear.
Is it only my problem?
