I have successfully installed Node and AngularCLI on my local system. And everything was okay. I have:

Angular CLI: 13.1.1
Node: 16.13.1
Package Manager: npm 8.1.2
OS: win32 x64

Angular:
...

Package                      Version
------------------------------------------------------
@angular-devkit/architect    0.1301.1 (cli-only)
@angular-devkit/core         13.1.1 (cli-only)
@angular-devkit/schematics   13.1.1 (cli-only)
@schematics/angular          13.1.1 (cli-only)

However, when I try to install Angular project with ng new myproject, I got this error:

- Installing packages (npm)...npm WARN deprecated flatten@1.0.3: flatten is deprecated in favor of utility frameworks such as lodash.
npm WARN deprecated querystring@0.2.0: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.

I am doing the installation on my local system, without any security.

I did:

npm cache clear --force

The problem is still there.

How do I get this sorted out?

Thanks
