I have an ionic project that I haven't updated for some time.
The project worked well and I installed the ionic app on many devices.
Today I downloaded the code from git hub and then run the command npm install but the command ended with dependencies errors:

MacBook-Pro-di-Silvia:scorekeeper gottasilvia$ npm install

I tried to follow the suggested commands but the result did not change.
How can I install and update all the packages without any dependency issue?
Many thanks
