ModuleNotFoundError：在Django Metamask安装中没有名为“ ethereum”的模块

Question

现在，我正在尝试django和metamask连接的工作。但是当我尝试运行服务器时，却遇到了

...
 urlconf_module = import_module(urlconf_module)
  File "C:\Users\Emma\AppData\Local\Programs\Python\Python37-32\lib\importlib\__init__.py", line 127, in import_module

  File "C:\Users\Emma\Desktop\web3start\web3auth\utils.py", line 2, in <module>
    import ethereum
ModuleNotFoundError: No module named 'ethereum'

所以我尝试了诸如 pip install ethereum，pip install -r requirements.txt，pip install'rlp == 0.6.0'，但仍然出现错误。有人可以帮我吗？
