Hello Odoo community:

   I was trying to install a third-party module to odoo 16, but it shows that " Unable to install module xxx because an external dependency is not met: Python library not installed: Crypto"

  I have installed the required file using anaconda successfully (anaconda/win-64::pycryptodome-3.15.0-py39h2bbff1b_0) under python 3.9.17 environment, but my odoo is runing under python 3.11 environment, I therefore try to install with cmd. However, I cannot install using "pip install pycrypto", with the following error message: 

"C:\Program Files\Odoo 16\python\Scripts>pip install pycrypto

[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.

ERROR: Failed building wheel for pycrypto

Failed to build pycrypto

I have made sure that the "Microsoft C++ Build Tools" is in my system. 

Please let me know what else I can do to fix the error. Thank you so much!
