Crypto Error on import pyrebase

I'm getting the following error when running import pyrebase:

>>> import pyrebase

It was working fine just a few days ago.

Thanks for your hard work!

@benthecoder I haven't looked into this since reporting the error, so no I haven't. I'm waiting for a new version that will (fingers crossed) fix it.

I unistalled pycryptodome and installed pycryptodome again and it is now working

pip uninstall pycryptodome
pip install pycryptodome

An alternative solution is to install Pyrebase4.

This

I unistalled pycryptodome and installed pycryptodome again and it is now working
pip uninstall pycryptodome
pip install pycryptodome
This worked for me! Thanks!

This worked for me, I updated my project from python 3.7 to 3.11 and after installing pycrypto I faced an error.
error: value |= 2L ** (N-1) # Ensure high bit is set
I searched for the solution and here I got it so I just installed pycryptodome and it worked for me.
