I am trying to create a virtual environment and I get stuck at the point where I need to source the  new environment:
conda info -e
# conda environments:
#
base                  *  /Users/fwrenn/anaconda3
test_env                 /Users/fwrenn/anaconda3/envs/test_env
source ~/anaconda3/bin/activate test_env
_CONDA_ROOT=/Users/fwrenn/anaconda3: Command not found. Badly placed ()'s.
Can someone tell me what's wrong here? and how can I solve this?
