Thank you but it is not about installing steem. It is about importing account to steempy

Ok, I know your problem, you have pycryptodome installed which is not compatible with steem. Steem uses pycrypto. So uninstall pycryptodome and install pycrypto.

I can see this on your error message. new() missing 1 required positional argument

Yes, you right. I tried that but same problem occurs.

start python
and enter
from Crypto.Cipher import AES
AES.__file__
When you recieve something like ...Crypto\Cipher\AES.py' your are fine.
..Cryptodome\Cipher\AES.py' means the wrong library is installed.
