Angular 安装：npm warn deprecated /module angular can not find

Question

Could someone help me with this problem:

1. i install "npm install -g @angular/cli" on my computer
2. them i go to git to clone the documents to a repository called 'frontend'
3. i open the CMD in the 'frontend' folder and try to run 'ng serve'(node have been already installed)

And now in the cmd line:

npm warn deprecated request@2.88.2: request has been deprecated.....etc
...
can not find module'@angular-devkit/build-angular/package.json'

How can i make this work?

PS, since i already installed:node/angular so i do not need to run 'npm install' inside folder before 'ng serve' is that right?

Install @angular-devkit/build-angular as dev dependency. This package is newly introduced in Angular 6.0

npm install --save-dev @angular-devkit/build-angular
