Getting a "AttributeError: module 'hashlib' has no attribute 'scrypt'" during the tutorial

[SethBashamDev]

My code matches 1 for 1; followed the tutorial to the T and I am getting the error posted in the title. Can't seem to get an answer anywhere.

What version of Python are you using and where did you install it from? scrypt is available in all supported builds of Python.

https://docs.python.org/3/library/hashlib.html#hashlib.scrypt note the docs say it was added in 3.6.

Nice! I installed python3.10 via brew, and the problem is solved.

Note that both the system and brew Python's are not intended for "normal" development. You'd only develop against them if you expect to install next to and use them. Typically, you should use the official installers available at https://python.org.

I'm studying Flask and i create a Flask project named pythonbbs. In define UserModel, i imported the function generate_password_hash from package werkzeug.security for encryption the password from front html. In Windows, it runs well. but when i pull codes to centos 7.9, i also got this error. My python version is 3.9.0 in linux but 3.9.16 in windows. What need i do to resolve this problem?

start by not using an ancient python version

Edit 0: My Versions
Python 3.12.4
OpenSSL OpenSSL 3.3.1
macOS Sonoma 14.5

I have the same issue, but I'm using Python 3.12 and I just freshly installed the tutorial folder by cloning it from github with the tutorial-steps given. Is there anything else I might check? Any other package seems to be up to date as well.

Edit 1:
Another thing I tried: I imported werkzeug into a separate scratch file and tested the generate_password_hash(password) and it worked fine. It's just within the Flaskr folder, where I get this AttributeError.

Edit 2:
I just updated LibreSSL as well as OpenSSL to it's latest version, the issue still appears.

我不确定这是不是Werkzeug的某个版本导致的问题。 generate_password_hash(password)的 default method变成了scrypt。 我是在调用generate_password_hash(password,method='pbkdf2')时显示的制定method为pbkdf2来解决的此问题。
