I have only 3 months experience in angular, I tried downgrading the versions but it still gave error also tried to google the solution but didnt find the right solution, would appreciate any help, Thank you.
Looks like it's a problem with Peer Dependencies try with npm install --legacy-peer-deps.
You can skip peer dependency conflict checks by running npm install --legacy-peer-deps or you can set npm config set legacy-peer-deps true and then run npm install once again.
If you want to run the angular code of your friend in your machine then follow the steps.
step 1: this can be happen due to version mismatch in your node version and your friends node version and npm version. C://projectFolder> node --version then C://projectFolder> npm -v
step 2: If the version is mismatch then uninstall node in your machine then restart then install the node version of your friend.
step 3: run the below code example
1.
npm install npm@[version]
in my machine
npm install -g npm@6.2.0
now run npm install in your project folder
npm install
now npm start or ng serve to work perfectly
