Occasionally the conda environment is destroyed. I don't have time to follow it in detail, so I put it back in and solved it. If you don't like the crowded environment, re-enter it.

See the status of conda

conda info --e

Erase the conda environment

source deactivate
conda remove --name py27 --all
conda remove --name py35 --all

View the status of pyenv

pyenv versions

Erase the pyenv environment

pyenv uninstall miniconda3-4.0.5
pip uninstall conda

Put pyenv and conda

pyenv install miniconda3-4.0.5
conda create -n py27 python=2.7
conda create -n py35 python=3.5
source activate py35

moved

I didn't get opencv until a while ago. Sometimes the environment is edited because of the library, so you can re-insert it.

enjoy your python life!!!
