How to fix ERROR in node_modules/chart.js/types/animation.d.ts(20,37): error TS1005: ',' expected. in chart.js

Question

I am working on an Angular 6 project where I want to create some charts using chart.js.

I installed chart.js using npm install chart.js and its version is like 3.5.1.

My TypeScript version is like 2.9.0.

So when I try to ng serve:

node_modules/chart.js/types/animation.d.ts(20,37): error TS1005: ',' expected.
node_modules/chart.js/types/animation.d.ts(20,46): error TS1005: ',' expected.

What is this and how to fix this?

Thanks

As others have stated, downgrading to chart.js version 2.7.3 fixed this for me. For anyone not super familiar with npm, here's the commands I used to update the package:

npm remove chart.js --save
npm install [email protected] --save

I specifically did this for my ionic 5 project. But it should also work for angular.
