已安装pycryptodome但无法导入Crypto模块的问题求助

我在Python项目里尝试使用pycryptodome库，可一直碰到这个错误：

ModuleNotFoundError: No module named 'Crypto'

下面是我已经做过的所有排查操作：

1. 安装pycryptodome #

我通过pip完成了库的安装：

PS C:\Users\Nathan> pip install pycryptodome
Requirement already satisfied: pycryptodome in c:\users\nathan\appdata\local\programs\python\python311\lib\site-packages (3.21.0)

2. 验证安装状态 #

我也确认了库的安装详情：

PS C:\Users\Nathan> pip show pycryptodome
Name: pycryptodome
Version: 3.21.0
Summary: Cryptographic library for Python
Home-page: https://www.pycryptodome.org
Author: Helder Eijs

Location: C:\Users\Nathan\AppData\Local\Programs\Python\Python311\Lib\site-packages
Requires:
Required-by: cart, eth-keyfile

3. 测试导入失败 #

但在Python交互环境里尝试导入时直接报错：

PS C:\Users\Nathan> python
>>> from Crypto.Cipher import AES
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'Crypto'

4. 尝试卸载重装 #

我试过完全卸载后强制重新安装：

PS C:\Users\Nathan> pip uninstall pycryptodome -y
Found existing installation: pycryptodome 3.21.0
Uninstalling pycryptodome-3.21.0:
  Successfully uninstalled pycryptodome-3.21.0
PS C:\Users\Nathan> pip install --force-reinstall pycryptodome
Collecting pycryptodome
  Using cached pycryptodome-3.21.0-cp36-abi3-win_amd64.whl.metadata (3.4 kB)
Using cached pycryptodome-3.21.0-cp36-abi3-win_amd64.whl (1.8 MB)
Installing collected packages: pycryptodome
Successfully installed pycryptodome-3.21.0

5. 检查冲突包 #

我也确认了系统中没有安装会导致冲突的pycrypto包：

PS C:\Users\Nathan> pip uninstall pycrypto -y
WARNING: Skipping pycrypto as it is not installed.

6. 验证Python路径 #

我检查了Python的sys.path，确认包含了pycryptodome所在的site-packages目录：

>>> import sys
>>> print(sys.path)
['', 'C:\\Users\\Nathan\\AppData\\Local\\Programs\\Python\\Python311\\python311.zip', 'C:\\Users\\Nathan\\AppData\\Local\\Programs\\Python\\Python311\\DLLs', 'C:\\Users\\Nathan\\AppData\\Local\\Programs\\Python\\Python311\\Lib', 'C:\\Users\\Nathan\\AppData\\Local\\Programs\\Python\\Python311', 'C:\\Users\\Nathan\\AppData\\Roaming\\Python\\Python311\\site-packages', 'C:\\Users\\Nathan\\AppData\\Local\\Programs\\Python\\Python311\\Lib\\site-packages', 'C:\\Users\\Nathan\\AppData\\Local\\Programs\\Python\\Python311\\Lib\\site-packages\\win32', 'C:\\Users\\Nathan\\AppData\\Local\\Programs\\Python\\Python311\\Lib\\site-packages\\win32\\lib', 'C:\\Users\\Nathan\\AppData\\Local\\Programs\\Python\\Python311\\Lib\\site-packages\\Pythonwin']

其中C:\\Users\\Nathan\\AppData\\Local\\Programs\\Python\\Python311\\Lib\\site-packages确实在路径列表中。

尽管做了这么多尝试，错误还是没有解决。为什么明明pycryptodome已经安装在正确的目录，我还是会碰到ModuleNotFoundError: No module named 'Crypto'？有没有其他我可以尝试的解决步骤？
