Running Existing Angular Project locally

Question

I am very new to Angular, I am trying to run an existing project of Angular on my machine. I have done a lot of tests and followed a lot of articles. But cannot run my project.

I have the project files like this:

I installed the nodejs on my system. And followed the following instructions as per an article:

change directory to our repo

cd myproject

installing Cli according to project readme file.

npm install -g @angular/[email protected]

install the repo with npm

npm install

install TypeScript typings

npm run typings-install -- Gives error: npm ERR! missing script: typings-install

Then I try the following:

npm install --global For following:

webpack (npm install --global webpack)
webpack-dev-server (npm install --global webpack-dev-server)
karma (npm install --global karma-cli)
protractor (npm install --global protractor)
typings (npm install --global typings)
typescript (npm install --global typescript)

start the server

npm start

-- Gives multiple error messages: Such as:

npm ERR! code ELIFECYCLE

-- For this I tried "npm cache clean" and then deleted "node_modules" and then installed packages again using: "npm install --save"

Then tried again: npm start it gave me same error "npm ERR! code ELIFECYCLE"

Also, this error message:

Cannot find module 'webpack/lib/node/NodeTemplatePlugin'

For this, I tried "npm uninstall -g webpack" and then: npm install --save-dev webpack webpack-cli html-webpack-plugin webpack-dev-server webpack-dev-middleware from this: Error: Cannot find module 'webpack/lib/node/NodeTemplatePlugin'

Tried running it again:

this time it gave me following error:

ERROR in ./node_modules/raw-loader!./node_modules/@angular/cli/node_modules/post
css-loader/lib??embedded!./node_modules/sass-loader/lib/loader.js??ref--8-3!./sr
c/styles.scss
Module build failed: Error: Cannot find module 'node-sass'

For this "Cannot find module 'node-sass'" I did the search again:

and found this command: npm install node-sass

i tried it and then tried starting again

Now I received ERROR in No NgModule metadata found for 'AppModule'.

And for this I tried the following from git cli issues 8798

remove the node_modules folder

rm -rf node_modules

remove the webpack

npm remove webpack

clean npm cahe

npm cache clean --force

install the latest version of angular cli

npm install --save-dev @angular/cli@latest

install the dependencies

npm install

now it's just testing

npm start our ng serve

Now it start giving me: Local workspace file ('angular.json') could not be found and wont work at all. To resolve this: I did: ng update @angular/cli --migrate-only --from=1.7.4

Which remove the error: "Local workspace file ('angular.json') could not be found" but now it gives me error

ERROR in src/app/web-player/albums/album-context-menu/album-context-menu.compon
nt.ts(13,14): error TS2515: Non-abstract class 'AlbumContextMenuComponent' does
not implement inherited abstract member 'getAllTracks' from class 'ContextMenuC
mponent<Album>'.
src/app/web-player/artists/artist-context-menu/artist-context-menu.component.ts
13,14): error TS2515: Non-abstract class 'ArtistContextMenuComponent' does not

nt<Artist>'.
src/app/web-player/context-menu/context-menu.component.ts(58,34): error TS2304:

nt.ts(15,14): error TS2515: Non-abstract class 'PlaylistContextMenuComponent' d
es not implement inherited abstract member 'getAllTracks' from class 'ContextMe
uComponent<Playlist>'.

What am i missing here? I tried a lot of articles from 3 days but cannot run it.

Also, I see different types of Warning and messages.

Read Me file in project:

# Client

This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 1.3.2.

## Development server

Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.

## Code scaffolding

Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.

## Build

Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `-prod` flag for a production build.

## Running unit tests

Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).

## Running end-to-end tests

Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
Before running the tests make sure you are serving the app via `ng serve`.

## Further help

To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).
