ERROR: Failed building wheel for cryptography
Failed to build cryptography
ERROR: Could not build wheels for cryptography which use PEP 517 and cannot be installed directly
Current pip version is : pip 20.3.4 (latest supported)
openssl version : OpenSSL 1.1.1
Also all required dependencies are installed.
If
pip install cryptography is done it successfully installs 3.3.2 version.
Kindly suggest.
I tried to install all dependencies but did not solved my problem.
Also attempted to install non patched cryptography-3.3.2 module from source but got the same error.
