“ng-new” not found in collection “@schematics/angular”

问题

I have deleted npm and node. In addition, I have deleted and restored homebrew. I downloaded npm and node from the online download site to restore them. I also downloaded the angular cli through npm. I located my desktop through the terminal and typed

ng new mag-board

to begin my angular project. I was prompted with the following error:

Schematic "ng-new" not found in collection "@schematics/angular".
Error: Schematic "ng-new" not found in collection "@schematics/angular".

I Deleted npm, Deleted node, and I Deleted Angular CLI

I reinstalled npm, node, and Angular CLI

I should be able to generate an Angular project from typing ng new mag-board

You can find the answer in https://github.com/angular/angular-cli/issues/10862

I'll short it for you:

first option:

sudo npm uninstall @schematics/angular

and

sudo npm i @schematics/angular

if it's not wroking, then:

Remove the node_modules folder in your home directory.

回答2:

Try this command in angular Command prompt :

npm install @schematics/angular updated
if this doesn't work try uninstall and install @angula/cli. Here's the command for installing and uninstalling angular-cli
npm uninstall @angular/cli
npm install @angular/cli

then use this command in your angular prompt:

npm install @schematics/angular updated
