can't run brand new angular project

First of all, YES, I did my research. I wen't through suggested 'Similar questions' here on stackoverflow and I googled two days in a row. I wasn't able to fix this problem yet.

The problem:

On my new PC I recently installed node.js, typescript and Angular.

I created a new project (let's call the app reminder) like so

ng new reminder --style scss --prefix rem --routing

Immediately I try to run it, just to make sure it works

ng serve

And this is what I get back

An unhandled exception occurred: Could not find the implementation for builder @angular-devkit/build-angular:dev-server

I've been looking for a solution since the day before yesterday - I tried to install the devkit/build-angular dev-server manually. I also tried multiple other things I found, but neither worked so far...

Any ideas, anybody?

Package                           Version
-----------------------------------------------------------
@angular-devkit/architect         0.13.9
@angular-devkit/build-angular     0.13.9
@angular-devkit/build-optimizer   0.13.9
@angular-devkit/build-webpack     0.13.9
@angular-devkit/core              7.3.9
@angular-devkit/schematics        8.1.0
@angular/cli                      8.1.0
@ngtools/webpack                  7.3.9
@schematics/angular               8.1.0
@schematics/update                0.801.0
rxjs                              6.3.3
typescript                        3.2.4
webpack                           4.29.0

THESE ARE JUST A FEW THINGS AMONG EVERYTHING I TRIED AND DIDN'T WORK:

// reinstall angular cli
npm uninstall -g @angular/cli
npm cache clean --force
npm install -g @angular/cli


// manually install devkit/build
npm install --save-dev @angular-devkit/build-angular


// reinstalled everything
uninstalled angular
uninstalled typescript
removed node
installed fresh node from nodejs.org
npm cache clean --force
npm chache verify
npm install @angular/cli --global

UPDATE: I uninstalled angular/cli 8 and installed angular/cli 7.3.5 back as it was. Now the server works. I'll wait for an answer to this question.

Try this (source):

$ npm uninstall -g @angular/cli
$ npm cache clean
$ npm install -g @angular/cli

Install @angular-devkit/build-angular as dev dependency. This package is newly introduced in Angular 6.0

npm install --save-dev @angular-devkit/build-angular

or,

yarn add @angular-devkit/build-angular --dev

I struggled with this for over a week, but none of the suggested (or googled) solutions worked.

I ended up 'reseting' my PC: settings -> recovery -> reset this PC

After clean Windows, npm and Angular installs everything works.

Can you tell which version of node and angular cli you have installed? You can find this by typing on a console:

node --version
ng --version

What do you mean by installing typescript? That's not required. All you have to do is install NodeJS and Angular CLI globally.

You could try to generate a default project, just to check your setup. The instructions can be found on the Angular website: https://angular.io/guide/setup-local
