index.ts is not part of the compilation output

Question

I am trying to compile my Angular application and am getting an error. It seems to be with the compiler not recognizing the index.ts file. I'm not sure why.

Below is the error:

ERROR in ./node_modules/datatable/index.ts
Module build failed: Error: node_modules\datatable\index.ts is not part of the compilation output. Please check the other error messages for details.

Does anyone have any suggestions on how to fix this? Thank you.

Answer 1

I had a similar issue with angular-bootstrap-md\index.ts

how I could fix it:

Just put the index.ts file to the tsconfig.jsons include block , see below:

{
  "compileOnSave": false,
  "compilerOptions": {
  "outDir": "./dist/out-tsc",
  "sourceMap": true,
  "declaration": false,
  "moduleResolution": "node",
  "emitDecoratorMetadata": true,
  "experimentalDecorators": true,
  "target": "es5",
  "typeRoots": [
    "node_modules/@types"
  ],
  "lib": [
    "es2017",
    "dom"
  ]  
},
"include": [
  "src/**/*",
  "node_modules/angular-bootstrap-md/index.ts"
  ]
 }

This was the simple fix- Run the following: npm install --save @ngtools/[email protected]
