An unhandled exception occurred: Cannot find module '@angular/compiler-cli/ngcc'

I've just started my first job and tasked to work on an old project which will be updated.

I've given a new computer so I installed node.js, Visual Studio new versions.

As I mentioned I am working with an old project on WebStorm and I get this error:

An unhandled exception occurred: Cannot find module '@angular/compiler-cli/ngcc'

When I searched it I found some solutions related to @angular/compiler-cli not with @angular/compiler-cli/ngcc.

I've tried:

Here is my package.json file

I was facing the same NGCC error while build esm module. I have solved this by simply changing target in the compilerOptions of your tsconfig.json from es5 to es2015

I think your problem is with your versions. I mean you are using so many different versions and they could not work well together

let me explain:

Angular CLI: 8.3.5 (latest version)

but for cdk, for 1 year ago: "@angular/cdk": "^6.4.2", "@angular/common": "^6.1.0",

typescript: 3.5.3 ( which probably wasn't there when angular 6.4 exist)

try what I suggest: (I struggled so many times with old project)

  1. Lucky shot: just run ng update --all=true --force=true (look at documentation for correct syntax) it might work, but even if it throw some exceptions, it provide guidelines which reference has a problem)

  2. Create a new angular project by using "ng new projectname"

a. Use "ng serve" to start your project If it works fine, you will be sure that your npm and node works fine (which is very important because it eliminates so many bug possibilities) (if it isn't, honestly reinstalling windows is almost fastest way)

b. after having a working template, just start adding other references to be sure that you dont have version mismatch (and don't forget ng serve and watching the output result). If you had version mismatch, try to upgrade them, or if not possible remove them (if it's an old library, you have to replace it anyway)

c. If it works with any problems, then ship your old code to this new folder and to try to remove your bugs
