我是Angular的新手，我正在嘗試在我的機(jī)器上運(yùn)行Angular的現(xiàn)有項(xiàng)目 . 我做了很多測(cè)試并且跟著很多文章 . 但無法運(yùn)行我的項(xiàng)目 .

我有這樣的項(xiàng)目文件：

我在我的系統(tǒng)上安裝了nodejs . 并根據(jù)文章按照以下說明操作：

將目錄更改為我們的倉(cāng)庫(kù)

cd myproject

根據(jù)項(xiàng)目自述文件安裝Cli .

npm install -g @ angular / cli @ 1.3.2

用npm安裝repo

npm安裝

安裝TypeScript打字

npm run typings-install - 給出錯(cuò)誤：npm ERR！缺少腳本：typings-install

然后我嘗試以下方法：

npm install --global用于以下內(nèi)容：

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)

啟動(dòng)服務(wù)器

npm start

提供多條錯(cuò)誤消息：例如：

npm ERR! code ELIFECYCLE

為此我嘗試了“npm cache clean”，然后刪除了“node_modules”，然后使用以下命令再次安裝了包：“npm install --save”

然后再試一次： npm start 它給了我同樣的錯(cuò)誤“ npm ERR! code ELIFECYCLE ”

此外，此錯(cuò)誤消息：

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

為此，我嘗試了"npm uninstall -g webpack"然后：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'

嘗試再次運(yùn)行它：

這次它給了我以下錯(cuò)誤：

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'

對(duì)于這個(gè)“ Cannot find module 'node-sass' ”我再次進(jìn)行了搜索：

并找到了這個(gè)命令：npm install node-sass

我嘗試了，然后嘗試重新開始

現(xiàn)在我收到 ERROR in No NgModule metadata found for 'AppModule'.

為此我從git cli問題8798嘗試了以下內(nèi)容

刪除node_modules文件夾

rm -rf node_modules

刪除webpack

npm remove webpack

干凈的npm cahe

npm cache clean --force

安裝最新版本的角度cli

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

安裝依賴項(xiàng)

npm install

現(xiàn)在它只是測(cè)試

npm start our ng serve

現(xiàn)在它開始給我：找不到本地工作區(qū)文件('angular.json')，根本無法工作 . 解決這個(gè)問題：我做了：n g update @angular/cli --migrate-only --from=1.7.4

刪除錯(cuò)誤：“無法找到本地工作區(qū)文件('angular.json')”但現(xiàn)在它給了我錯(cuò)誤

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'.

src/app/web-player/artists/artist-context-menu/artist-context-menu.component.ts

13,14): error TS2515: Non-abstract class 'ArtistContextMenuComponent' does not

mplement inherited abstract member 'getAllTracks' from class 'ContextMenuCompon

nt'.

src/app/web-player/context-menu/context-menu.component.ts(58,34): error TS2304:

Cannot find name 'TrackList'.

src/app/web-player/playlists/playlist-context-menu/playlist-context-menu.compon

nt.ts(15,14): error TS2515: Non-abstract class 'PlaylistContextMenuComponent' d

es not implement inherited abstract member 'getAllTracks' from class 'ContextMe

uComponent'.

我在這里缺少什么？我從3天開始嘗試了很多文章但是無法運(yùn)行它 .

此外，我看到不同類型的警告和消息 .

在項(xiàng)目中自述文件：

# 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).
