Errors present for correct import paths using baseUrl in tsconfig.json.

[BBaysinger]

I'm getting errors for paths that are correct, using root relative imports in Angular, via this solution. My linter error looks like:

Cannot find module 'header/header.component'.

My tsconfig.json file:

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "app",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2017",
      "dom"
    ]
  }
}

My src/tsconfig.json file:

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "module": "es2015",
    "types": [],
    "baseUrl": "app"
  },
  "exclude": [
    "src/test.ts",
    "**/*.spec.ts"
  ]
}

The project compiles fine, and accepts the import paths, but linter-tslint thinks the paths are wrong.

I am using Angular 6.0.3, and TypeScript 2.7.2.
