Thank you Sean and Sebastian for your replies. I don't have a .condarc in my home directory. I don't know where it picks up the channels.
In any case, when I tried to install something that does not exist, it responds like below. I checked all the channels. rdkit is only available on the first channel. But all rdkit versions are there. I don't know why it picks up 2018.03.2.0 in particular. And if it's because of some python version constraint, the newest rdkit that is compatible with python 2.7 should be 2018.09.3.0, not 2018.03.2.0. Hence there must be somewhere in my set up that specifies 2018.03.2.0. I just don't know where.
