node-sass is deprecated

[DavidArcha]

Details

In Angular15 when we try to install "NPM i" we are getting below error. We installed Python 3.1.0 in our system then also it was not resolved. If we used "--legacy-peer-deps" along with "NPM i " it is installing. But in server build getting failed. So client asking to fix this.

Error Starts:

The problem is NOT Python:

error gyp verb find Python - version is "3.10.10"
error gyp info find Python using Python version 3.10.10 found at "C:\Users\DAVIDARCHA\AppData\Local\Programs\Python\Python310\python.exe"
