Angular CLI can't find modules

Question

I have copied a project in a new repository.

Then I tried to delete node_modules folder then tape :

npm install

to install missing dependencies

But after installation and when I run my project using angular-CLI it does not find modules and show this errors:

ERROR in /home/haddad/projects/portfolio/src/app/app.component.ts (1,62): Cannot find module '@angular/core'.

ERROR in /home/haddad/projects/portfolio/src/app/app.component.ts (2,54): Cannot find module 'ngx-fullpage'.


ERROR in /home/haddad/projects/portfolio/src/app/menu-accueil/menu-accueil.component.ts (2,31): Cannot find module '@angular/material'.

Here's my package.json

    "tslint": "~5.3.2",
    "typescript": "~2.3.3"
  }
}

I have also uninstall angular-cli then reinstall it back but no result .

UPDATE , I have noticed that the missing modules are the locked directory @angular in node_modules folder.

even after using sudo chown -R ./node_modules/ I got the same error

Why you need administrator rights when you just install dependencies? I use macOS and I never install deps using sudo.... — Sharikov Vladislav, Aug 27 '17 at 21:55
I don't say that the problem is that. I am just wondering why you use sudo there. — Sharikov Vladislav, Aug 27 '17 at 22:16
When exactly cli says that about modules? Do this modules really exist in node_modules? — Sharikov Vladislav, Aug 27 '17 at 22:16
yes they exist. Other module are missing but I have not added them in my post. It shows that when I use ng serve. — infodev, Aug 27 '17 at 22:25
Are you sure you're running `npm install` in the correct directory (i.e. `/home/haddad/projects/portfolio`)? Just wondering... — Will, Aug 27 '17 at 22:46
@infodev update the packages to latest version. delete node_modules folder and install the packages using npm install — Vignesh, Aug 28 '17 at 04:19
Try what @RahulSingh said. And if that doesn;t work, try changing the permissions of the node_modules, instead of changing the owner. — rootkill, Aug 28 '17 at 18:43
