This is not a web package error, but from ESLint, in particular from eslint-plugin-import.
Using built-in loaders is generally not recommended, and the ESLint rule is import / no-webpack-loader-syntax to warn you about this. If you want to use the built-in bootloaders and do not want ESLint to file complaints, you can disable this rule in .eslintrc.
"rules": {
"import/no-webpack-loader-syntax": "off"
