Failed at the core-js postinstall script error - node.js

Question

I am facing the following errors when I try to install node modules in an existing Angular project. I am trying to install the node modules in windows machine(Win32 X64).
> core-js#2.6.12 postinstall node_modules\babel-runtime\node_modules\core-js
> node -e "try{require('-/postinstall')}catch(e){}"

The following are the versions installed in my system
AngularCli : 8.3.29
Node : 14.17.1
NPM: 8.2.12
I have tried deleting node modules folder and running npm cache clean --force and reinstalling node modules , also tried uninstalling nodejs and deleting the npm-cache folder and reinstalling again.
Still I am facing the same issue. Any help would be appreciated.

This error means that the postinstall script is fork-and-exec'ing bash, which is not present on Windows. You need to run this from a Bash emulator like MINGW64 (Git Bash).
