Angular TSLint - Cannot find builder "@angular-devkit/build-angular:tslint"

Question

When I try to run command ng lint --fix cli throws this error:

An unhandled exception occurred: Cannot find builder "@angular-devkit/build-angular:tslint".
See "C:\Users\MOE89A~1.ZAR\AppData\Local\Temp\ng-Ijc3an\angular-errors.log" for further details.

My lint confing in angular.json:

"lint": {
  "builder": "@angular-devkit/build-angular:tslint",
  "options": {
    "tsConfig": [
      "projects/wepod-app/tsconfig.app.json",

    ],
    "exclude": [
      "**/node_modules/**"
    ]
  }
},

Answer 1

From v13 angular doesn't use tslint anymore due to deprecation.

Run ng add @angular-eslint/schematics to add eslint to your application.

It will use tslint-to-eslint-config to migrate you to eslint automatically.

It will generate a .eslintrc.json file and migrate tslint.json to it.

Nothing else is needed to be done.

How do you run it? – Nutty

ng add @angular-eslint/schematics it will do the rest automatically. – Piane

Thank you. This was suggested by the cli, but I wasn't sure if this is the correct way to do when working with tslint. – Tritanopia

Well it did not work in my case. It says "Packages installed successful", but theres no migrated .eslintrc.json, and runing ng lint still gives the same error message. I can also see that the lint config in angular.json is still refering tslint. – Automation

What is your angular version? @PeterStjernholmMeldgaard – Piane

Looks like you now have to run npx tslint-to-eslint-config to get .eslintrc.json converted – Brackett

Answer 2

@MahdiJoon is a great answer! I think that it will work for most projects.

I'm adding this answer for developers who have already deleted tslint manually, like I did.

If you did that, like me, then:

1. ng add @angular-eslint/schematics to install eslint
2. ng g @angular-eslint/schematics:convert-tslint-to-eslint <project-name> to migrate tslint.json config to .eslintrc.json
3. (optional) run the previous command for any other project (e.g. e2e)

Cannot set properties of undefined (setting 'lint') – Timoteo

are you on angular@13? This answer has more than a year, it may need some adjustments to work with the current toolkit – Dissyllable

yes. Angular 15. Totally up to you man, if you want to update the answer – Timoteo

Hi @AqeelAshiq, unfortunately I'm not working on Angular right now, if you want, send an edit request, I'll add your version to the answer – Dissyllable
