I am updating Angular version from 7 to 8. But getting peer dependency error

I tried using --force , but of no use.

Tip: use powershell or VS Code's terminal. It will allow you to easily copy text. — Captain Kenpachi, Jun 01 '20 at 08:37

you need to install the compatible version of each dependency here's the code for that

npm i --save dependencyName@version

Can you post some example from above error... I am new to angular @Ess – Owais Jun 01 '20 at 09:11
if you already have your dependency installed then use this `ng update swimlane/ngx-charts@~8.2.12` otherwise do it this way `npm i swimlane/ngx-charts@^8.2.12 --save`.
