我是Angular的新手，我正在尝试在我的机器上运行Angular的现有项目 . 我做了很多测试并且跟着很多文章 . 但无法运行我的项目 .

我有这样的项目文件：

我在我的系统上安装了nodejs . 并根据文章按照以下说明操作：

将目录更改为我们的仓库

cd myproject

根据项目自述文件安装Cli .

npm install -g @ angular / cli @ 1.3.2

用npm安装repo

npm安装

安装TypeScript打字

npm run typings-install - 给出错误：npm ERR！缺少脚本：typings-install

然后我尝试以下方法：

npm install --global用于以下内容：

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)

启动服务器

npm start

提供多条错误消息：例如：

npm ERR! code ELIFECYCLE

为此我尝试了“npm cache clean”，然后删除了“node_modules”，然后使用以下命令再次安装了包：“npm install --save”

然后再试一次： npm start 它给了我同样的错误“ npm ERR! code ELIFECYCLE ”

此外，此错误消息：

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

为此，我尝试了"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'

尝试再次运行它：

这次它给了我以下错误：

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'

对于这个“ Cannot find module 'node-sass' ”我再次进行了搜索：

并找到了这个命令：npm install node-sass

我尝试了，然后尝试重新开始

现在我收到 ERROR in No NgModule metadata found for 'AppModule'.

为此我从git cli问题8798尝试了以下内容

删除node_modules文件夹

rm -rf node_modules

删除webpack

npm remove webpack

干净的npm cahe

npm cache clean --force

安装最新版本的角度cli

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

安装依赖项

npm install

现在它只是测试

npm start our ng serve

现在它开始给我：找不到本地工作区文件('angular.json')，根本无法工作 . 解决这个问题：我做了：n g update @angular/cli --migrate-only --from=1.7.4

删除错误：“无法找到本地工作区文件('angular.json')”但现在它给了我错误

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'.

我在这里缺少什么？我从3天开始尝试了很多文章但是无法运行它 .

此外，我看到不同类型的警告和消息 .

在项目中自述文件：

# 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).
