将目录更改为我们的仓库

Question

我是Angular的新手，我正试图在我的机器上运行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进行操作：

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

使用npm

安装repo

npm install

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 以下是：

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：如：

npm ERR! code ELIFECYCLE

- 为此我试过＆＃34; npm cache clean＆＃34;然后删除＆＃34; node_modules＆＃34;然后使用以下命令再次安装软件包：＆＃34; npm install --save＆＃34;

然后再次尝试：npm start它给了我同样的错误＆＃34; npm ERR! code ELIFECYCLE＆＃34;

此外，此错误消息：

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

为此，我尝试了＃34; npm uninstall -g webpack＆＃34; 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'

为此＆＃34; Cannot find module 'node-sass'＆＃34;我再次进行了搜索：

找到此命令：npm install node-sass

我尝试了，然后再次尝试重新开始

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

为此，我尝试了以下来自git cli问题8798

删除node_modules文件夹

rm -rf node_modules

删除网络包

npm remove webpack

清理npm cahe

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

现在它只是在测试

npm start our ng serve

现在它开始给我：无法找到本地工作区文件（＆＃39; angular.json＆＃39;）并且根本无法工作。为了解决这个问题：我做了：n g update @angular/cli --migrate-only --from=1.7.4

删除错误：＆＃34;无法找到本地工作区文件（＆＃39; angular.json＆＃39;）＆＃34;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>'.

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？我从3天开始尝试了很多文章但是无法运行它。

另外，我看到了不同类型的警告和消息。

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).

Answer 1

那应该容易得多...

按原样保存项目文件

运行npm install

由于您拥有package.json文件，它将读取并安装所有依赖项。

然后根据需要运行npm audit fix（终端会告诉您）。

祝你好运！

Answer 2

尝试ng-serve --open 它将编译您的项目并直接在浏览器中打开

Answer 3

运行以下命令

 npm uninstall -g @angular/cli
 npm cache verify
 npm install -g @angular/cli@next
 npm update

然后

 ng serve

我希望现在有效。如果您在遇到任何错误时发表评论。

Answer 4

将文件.angular-cli.json重命名为angular.json，然后重新运行ng serve --open命令。

Answer 5

cd my-repo

npm install
ng serve或ng serve --open

然后您将找到Localhost。

要清除缓存：

npm cache clean

在本地运行现有Angular项目

将目录更改为我们的仓库

根据项目自述文件安装Cli。

使用npm

安装TypeScript打字

然后我尝试以下方法：

启动服务器
