cannot import name 'asn1' from 'cryptography.hazmat.bindings._rust'

[Luancem]

hello,
I have installed jwt-1.3.0-py3-none-any.whl and cryptography-35.0.0-pp38-none-linux_x86_64.whl 。
But it reported below error when I "import jwt" 。 Could someone help me? Thanks very much!

You appear to be using pypy 3.10, but have a pypy 3.8 wheel. How did you install cryptography?

[Luancem]

Thanks alex for reply!
This is my installation steps.

The pp38 wheel will not work with PyPy 3.10 as PyPy does not have a stable interface. You need a pp310 wheel. This will require you to use a newer version of cryptography that ships a wheel compatible with your PyPy or else compile it yourself.

Thanks very much. It works well after jwt1.3.1 and cryptography41.0.2 installation.

Thanks again!
