I have tried reinstalling the node js package and setting proxy to off using:


The issue is still there. What I am doing wrong?


When I run the following command:

This is not related to http proxy.

You have dependency conflict (incorrect and potentially broken dependency) as it says, So try to to run the command with --force, or --legacy-peer-deps. If it doesn’t take effect, the temporary solution is using prior versions of the node (Downgrading node version) as it causes to happen such this errors sometimes.

Update based on OP’s Update:

As you see, it fires the following error :

No matching version found for @angular/http@^9.1.4.

Take a look at angular/http page. Note that the latest version for that deprecated package is 7.2.16 while you request an upper version (e.g ^9.1.4)! So, try to check the project dependencies and follow the raised errors in order to solve the problem.
