I have a problem in installing langchain on my Mac M1 within my Jupyter notebook.
I tried:
!pip install langchain
The output was:

However, when I try to import the langchain:
import langchain
It gives me the below error:

I tried also:
conda install langchain -c conda-forge
But same error emerges.
Any help please?
Thanks a lot!
