@ angular / cli安装后无法正常工作

Question

I have installed the @angular/cli on my MacBook machine. Node server version is v6.9.5 and the npm version is 3.10.10. I have ran the following command to install the @angular/cli.

sudo npm install -g @angular-cli

When I run the ng help command or any command for ng. It shows me the following error

Parsing .angular-cli.json failed. Please make sure your .angular-cli.json is valid JSON. Error: SyntaxError: Unexpected token u in JSON at position 22

InvalidConfigError: Parsing .angular-cli.json failed. Please make sure your

I also uninstalled and @angualr/cli and clear the cache then reinstalled @angualr/cli. I run the following command.

sudo npm uninstall -g @angular-cli 
npm cache clean sudo 
npm install -g @angular-cli

Still the same issue is appearing.

Answer 1

该包被称为@angular/cli ，所以npm install -g @angular/cli 。

Answer 2

@angular-cli is the previous version. Now you need to

npm install -g @angular/cli

to work with @angular/cli version

Answer 3

The package you mentioned is not valid. For fresh installation use npm install -g @angular/cli . Check here for more details https://github.com/angular/angular-cli#installation

angular-cli uses angular.cli.json. whereas @angular/cli uses .angular.cli.json

i also face same issue, so i tried this method given below.

Clean uninstall of angular-cli, like npm uninstall -g angular-cli Clone this angular-cli repo, Go to the angular-cli repo folder, and run npm link, Go to my project folder Run npm link angular-cli Now to run ng command, I use ./node_modules/angular-cli/bin/ng from my project folder

Answer 5

你需要全局安装@ angular / cli才能在任何地方使用它。要全局安装它使用cmd'npm i -g @ angular / cli'，其中-g表示global.Even将你的角度版本更新为latest.I认为错误是因为在较旧版本的angular中，angular.json文件名曾经以不同方式保存，其名称在新版本或最新版本中保存的方式不同，因此安装后可能无法读取angular.json文件。
