Question about updating my angular project

Question

I need to update my angular project but I'm having some issues. It shows me the following message:

Your global Angular CLI version (8.0.1) is greater than your local
version (1.7.4). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".

Error: Cannot update safely because packages have conflicting dependencies. Package @angular/core would need to match both versions "7.2.15" and "8.0.0, which are not compatible.

When it comes to upgrading your Angular project in general, simply run this:

ng update

Otherwise, if you want to perform an upgrade on just the CLI, you can the specific package as an option

ng update @angular/cli

Or directly install via npm

npm install --save-dev @angular/cli

If you need to do a hard reset, you can first install the CLI globally, followed by updating the one in your project itself.

npm uninstall -g @angular/cli
npm cache verify
npm install -g @angular/cli@latest

Then, you cd to our project directory,

rm -rf node_modules dist 
npm install --save-dev @angular/cli@latest
npm i 
ng update @angular/cli 
ng update @angular/core
npm install --save-dev @angular-devkit/build-angular
