Hi @Gagandeep_Singh. You need to downgrade the werkzeug.

This are the steps:

cd frappe-bench/env/bin
source activate
pip install --force-reinstall werkzeug==0.16.0
deactivate

After going this steps try to install erpnext again

you could use version-12-hotfix as the branch instead where this issue is fixed and switch branches to version-12 after the next release of Frappe.
