I have the same issue when I run ionic build then it throws error:
.tmp/app/main.prod.ts:4:36
[00:26:58] Cannot find module ‘./app.module.ngfactory’.
[00:26:58] ngc failed
[00:26:58] ionic-app-script task: “build”
[00:26:58] Error: Error
There is no app.module.ngfactory generated
Hi @crash21 , Did you solve the error?
I solved mine by ::
- removing: .tmp, node_modules, www
- update my package.json
- then run the following command ::
npm install
ionic build android
ionic run android
This links maybe can help you also:
Which version of Typescript are you using? Latest version (2.1.x) is not yet compatible with Angular/Ionic. For me this was causing the error.

I did no luck
Really wierd…
Btw in my package.json dependencies I have:
“devDependencies”: {
“@ionic/app-scripts”: “latest”,
“typescript”: “^2.0.9”
},
So they were already in latest version
Can you please show your ionic info?
