My question is that,
if I run
which python
it returns
/opt/anaconda3/bin/python
However, If I run
which python-config
It returns
/usr/bin/python-config
which is the built-in python 2.7 in macbook.
How can I change the config into the current python that I'm using?
Check if there is a python-config or python3-config in /opt/anaconda3/bin. If there is a file named python3-config, you should run python3-config instead. If there is no python3-config, likely you don't have python-config installed for your conda environment. You can run pip install python-config (make sure you run pip under your anaconda environment).
