Cannot find type definition file for '$'

Question

I recently tried upgrading my Angular 4 project to angular 5 to be able to use the @angular/material datatable features but am having errors building my app after upgrading all angular dependencies to version 5.

I get the error:"ERROR in error TS2688: Cannot find type definition file for '$'"

I'm working with angular-cli and here is my package.json

Error upon build:

Has anyone gone through similar issues and figured out a solution?

Answer 1

Found the problem. In my tsconfig.app.json file I had a "$" included in the types array for compilerOptions. I'm not sure how that got there but removing it fixed the issue.

I basically changed the src/tsconfig.app.json file from

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "module": "es2015",
    "baseUrl": "",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "types": ["JQuery", "$"]
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ]
}

to

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "module": "es2015",
    "baseUrl": "",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "types": ["JQuery"]
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ]
}
