Can you try installing on just normal Python/pip3 (not anaconda)? Does that work?

By default the python interepter is the Anaconda one, So I used the full path /usr/bin/python in bash to use the default python interpreter. it works! Thanks

For other people who come here with the same issue, my solution is

pip3 uninstall pytest
pip3 install pytest

Note it's pip3 instead of pip since I'm using Python3
