ImportError: cannot import name 'safe_str_cmp' from 'werkzeug.security'
This page explains How to Fix ImportError: cannot import name 'safe_str_cmp' from 'werkzeug.security'
​Werkzeug, the core dependency of Flask, is a comprehensive WSGI web application library. Version v2.1.0 deprecates a few helpers, including safe_str_cmp. Here is the update history:
v2.0.0
pbkdf2_hex, pbkdf2_bin, and safe_str_cmp are deprecated. hashlib and hmac provide equivalents.
v2.1.0
Remove the pbkdf2_hex, pbkdf2_bin, and safe_str_cmp functions. Use equivalents in hashlib and hmac modules instead.
​

How to Fix

Freeze the Werkzeug to the latest stable version prior to v2.1.0. The recommended version is Werkzeug==2.0.3.
