Try removing package-lock.json and then npm install. This worked for me:

cd <your-project-directory>
rm package-lock.json
npm install

  1. Remove package-lock.json

  2. Remove node_modules,

  3. and then install packages using npm install.

This resolved issue for me.

You need to disable your antivirus software and run cmd as an administrator. Don't forget disabling the windows firewall. As for the deprecated Core-js 2.6.10 I'm facing the exact same issue but at least it's a warning you can ignore. I've tried reinstalling Angular cli and manually updating Core-js to the latest version using npm install -g core-js@latest unfortunately neither worked. Also fsevents seems to be Mac related and nothing to worry about.

You need to confirm whether the Typescript is installed and after installing typescript it worked for me

running the below comment will show the typescript version

tsc -v

If it shows some error install the typescript

npm install -g typescript

If then typescript is installed you can try checking the Angular Cli version

ng --version

If it shows some error then install Angular Cli Ref: https://cli.angular.io/

npm install -g @angular/cli
