【问题描述】：
我对 Angular 很陌生，我正在尝试在我的机器上运行一个现有的 Angular 项目。我做了很多测试并关注了很多文章。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。 并按照文章遵循以下说明：
将目录更改为我们的仓库
cd 我的项目
根据项目自述文件安装cli。
npm install -g @angular/cli@1.3.2
使用 npm 安装 repo
npm 安装
安装 TypeScript 类型
npm 运行类型安装 -- 给出错误：npm ERR！缺少脚本：打字安装
然后我尝试以下方法：
npm install --global 如下：
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
-- 给出多个错误消息： 如：
npm ERR! code ELIFECYCLE
-- 为此，我尝试了“npm cache clean”，然后删除了“node_modules”，然后再次使用：“npm install --save”安装了包
然后再次尝试：npm start 它给了我同样的错误“npm ERR! code ELIFECYCLE”
另外，这个错误信息：
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 来自：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：
找到这个命令：npm install node-sass
我试过了，然后又开始尝试
现在我收到了ERROR in No NgModule metadata found for 'AppModule'.
为此，我从 git cli issues 8798 尝试了以下操作
删除 node_modules 文件夹
rm -rf node_modules
删除 webpack
npm remove webpack
清理 npm 缓存
npm cache clean --force
安装最新版本的 angular cli
npm install --save-dev @angular/cli@latest
安装依赖项
npm install
现在只是测试
npm start our ng serve
现在它开始给我：找不到本地工作区文件（'angular.json'）并且根本无法工作。
为了解决这个问题：我做了：ng update @angular/cli --migrate-only --from=1.7.4
删除错误：“找不到本地工作区文件（'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<Album>'.
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<Artist>'.
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<Playlist>'.
我在这里缺少什么？ 3天试了很多文章都跑不了。
项目中的自述文件：
# 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).

【问题讨论】：
-
你能给我们看看你的 package.json 文件吗？
-
是的，我添加了有问题的 package.json 文件详细信息，请查看。
-
@Kadioo 谢谢，但给了我错误：'sudo' 不被识别为内部或外部命令、可运行程序或批处理文件。
-
@Kadioo 1st 运行正确，但另一个 *npm install typescript@'>=2.4.2
-
@Kadioo 尝试过并且运行正确，但仍然给出了我在问题中报告的最后一个错误。
