导入ibmq时出现MissingOptionalLibraryError

Question

在尝试加载 ibmq 时，使用 from qiskit import IBMQ 这行代码时，我遇到了以下错误，即使我已经运行了 pip install qiskit-ibmq-provider。

Unexpected exception formatting exception. Falling back to standard exception
Traceback (most recent call last):
  File "c:\Users\dhruv\AppData\Local\Programs\Python\Python311\Lib\site-packages\qiskit\__init__.py", line 169, in __getattr__
ImportError: cannot import name 'ibmq' from 'qiskit.providers' (c:\Users\dhruv\AppData\Local\Programs\Python\Python311\Lib\site-packages\qiskit\providers\__init__.py)

The above exception was the direct cause of the following exception:

During handling of the above exception, another exception occurred:

有没有人能给点建议？

谢谢
