File to import not found or unreadable: node_modules/@coreui/coreui/scss/bootstrap-variables.",

when I run npm start I get flowing error:

> node-sass-chokidar --include-path ./node_modules ./src/scss -o ./src/scss

{
  "status": 1,
  "file": "xxxxxx/src/scss/vendors/_variables.scss",
  "line": 3,
  "column": 1,
  "message": "File to import not found or unreadable: node_modules/@coreui/coreui/scss/bootstrap-variables.",
  "formatted": "Error: File to import not found or unreadable: node_modules/@coreui/coreui/scss/bootstrap-variables.\n        on line 3 of src/scss/vendors/_variables.scss\n        from line 2 of src/scss/vendors/chart.js/chart.scss\n>> @import \"node_modules/@coreui/coreui/scss/bootstrap-variables\";\r\n   ^\n"
}

I use following package :

"@coreui/coreui": "^2.0.2",
"@coreui/coreui-plugin-chartjs-custom-tooltips": "^1.2.0",
"@coreui/icons": "^0.2.0",
"@coreui/react": "^2.0.1",
"bootstrap": "^4.1.1",
"core-js": "^2.5.7",
"react": "^16.5.1",
"react-dom": "^16.5.1",
"react-scripts": "1.1.5"

Starting with @coreui/coreui v2.0.4 and up there is no need for an explicit import of bootstrap variables and functions into the template
The current version of src/scss/vendors/_variables.scss should look like this:

// Override Boostrap variables
@import "../variables";
@import "~bootstrap/scss/mixins";
@import "~@coreui/coreui/scss/variables";
