When trying to import qiskit I obtain following error:

Have I installed Qiskit to the target directory incorrectly?
I attempted to install Qiskit in Terminal using:
python3 -m pip install qiskit -t /opt/anaconda3/lib/python3.8/site-packages.
I navigated to the path manually and I could find all the qiskit modules, including the retworkx modules (whatever it may be).
If anybody has experienced this sort of error before and happens to know a fix, I would appreciate it very much.
import retworkx? $\endgroup$ – luciano Aug 23 '20 at 14:39
