ModuleNotFoundError: No module named 'Crypto' even through installed pycryptodome

Question

When I need to import Crypto in Python3.10 like this in macOS 13.4 with M1 chip:

from Crypto.Cipher import PKCS1_v1_5 as Cipher_pksc1_v1_5
from Crypto.PublicKey import RSA

def print_hi(name):
    print(f'Hi, {name}') 

if __name__ == '__main__':
    print_hi('PyCharm')

shows:

Unresolved reference 'Crypto' 

I have already tried to install pycryptodome like this:

pdm add pycryptodome

still could not fixed this problem. What should I do to fixed this issue?This is the pyproject.toml:

[project]
name = ""
version = ""
description = ""
authors = [
    {name = "JiangXiaoqiang", email = "[email protected]"},
]
dependencies = [
    "pycryptodome>=3.19.0",
]
requires-python = ">=3.10"
readme = "README.md"
license = {text = "MIT"}

this is the pdm list output:

> pdm list|grep py

this is the UI about how I facing issue:

this is the python which output:

and this is the pdm info output:

Instead of using from Crypto.Cipher import PKCS1_v1_5 as Cipher_pksc1_v1_5, try the more explicit import:

from Cryptodome.Cipher import PKCS1_v1_5 as Cipher_pksc1_v1_5
from Cryptodome.PublicKey import RSA
