I have created conda environments in the past without any problems. So, even this time I proceeded to create one.
conda create -n astropython anaconda
Next, the documentation recommended uninstalling any previous copies of astropy by running:
conda uninstall astropy
I did that, and now my conda is broken. If I run any command with conda, I get the following error traceback.
Traceback (most recent call last):

ImportError: No yaml library available.
To proceed, conda install ruamel_yaml
Running conda install ruamel_yaml again spits out the same traceback. My $PATH is correct, solution to No module named ruamel did not solve the issue.
So, I looked into the files and found that there was no ruamel_yaml folder in the site-packages dir. I copied the ruamel_yaml folder from $HOME/anaconda3/pkgs/ruamel_yaml0.15.71/ to $HOME/anaconda3/lib/python3.6/site-packages/. Now, when I run any conda commands, I get the following error:
