Unable to install into Angular 11 project

[mindscratch]

While trying to install into an Angular 11 project using Node 15.4.0 and NPM 7.0.15, it fails:

> npm install zingchart-angular
...
npm ERR! Found: @angular/common@11.0.9
npm ERR! node_modules/@angular/common
npm ERR!   @angular/common@"~11.0.5" from the root project
npm ERR! 
npm ERR! Could not resolve dependency:
npm ERR! peer @angular/common@"^8.2.14" from zingchart-angular@1.0.0

npm ERR!   zingchart-angular@"*" from the root project
npm ERR! 
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps

I was able to reproduce this using a brand new Angular 11 project using Node 15.4.0 and NPM 7.0.15:

> ng new zing-test
> cd zing-test
> npm install zingchart
> npm install zingchart-angular # this is where it fails

Need to use npm install zingchart-angular --legacy-peer-deps. Updating docs.

This seems to be a workaround not a fix.
Also see the error message of npm (version 7.7.4):
Fix the upstream dependency conflict, or retry
this command with --force, or --legacy-peer-deps
to accept an incorrect (and potentially broken) dependency resolution.

When is the library going to be upgraded to just support angular 11 (soon 12 is already coming) and this one is still fixed to Angular 8?

@zingsoftadmin is there a timeline when it will be at least angular 11 compatible?

@angeltg83 This appears to be a network problem, please reference this thread: npm/npm#6820
