Unable to resolve path with rootPathPrefix and no extension name.



.eslintrc.json

```json
{
"env": {
"browser": true,
"es6": true
},
"extends": "airbnb",
"globals": {
"Atomics": "readonly",
"SharedArrayBuffer": "readonly"
},
"parser": "babel-eslint",
"parserOptions": {
"ecmaFeatures": {
"jsx": true
},
"ecmaVersion": 2018,
"sourceType": "module"
},
"plugins": [
"react",
"import"
],
"rules": {},
"settings": {
"import/resolver": {
"node": {
"paths": [
"src"
],
"extensions": [
".js",
".jsx",
".ts",
".tsx"
]
},
"babel-plugin-root-import": {
"rootPathPrefix": "#",
"rootPathSuffix": "src"
}
}
}
}
```

I don't want to add extension name, and try my best to solve it. Finally, it's failed. I'm so confused and upset with it recently, someone can help me?

Start with the supplied .eslintrc.json and its import/resolver settings, then reproduce an extensionless import using the # rootPathPrefix. Trace how the resolver handles root-prefixed paths and compare that behavior with the configured extensions; done means the expected path resolves without an extension, or the limitation is clearly established and covered by an appropriate test.
