I used conda create --name qc-26 --clone base; conda activate qc-26; jupyter notebook
Whenever I ran,
from qiskit import BasicAer
I received the following error messages
ImportError: dlopen(/opt/anaconda3/envs/QC/lib/python3.8/site-packages/tweedledum/_tweedledum.cpython-38-darwin.so, 2): Symbol not found: _aligned_alloc
