Anaconda move to Python 3

I am trying to make my Anaconda Python 2 into Python 3 on my Mac, and have been trying almost everything now. Preferably I would want to move to 3.6 but I am yet to manage to get any Python 3 version working. I started with conda install python=3.6 but got dependency errors. Then I though if I download the Anaconda installer maybe it will update everything and there will be no more dependency errors, but the installation program told me to run conda update anaconda. I still get dependency errors though. This is what I get right now:

For version 3.6:

$ conda install python=3.6
Fetching package metadata .........
Solving package specifications: .


UnsatisfiableError: The following specifications were found to be in conflict:
  - argcomplete -> python 3.3* -> openssl 1.0.1*
  - argcomplete -> python 3.3* -> xz 5.0.5
  - python 3.6*
Use "conda info <package>" to see the dependencies for each package.

and for version 3.5:

$ conda install python=3.5
Fetching package metadata .........
Solving package specifications: .


UnsatisfiableError: The following specifications were found to be in conflict:
  - backports_abc -> python 3.4*
  - python 3.5*
Use "conda info <package>" to see the dependencies for each package.

What am I doing wrong and what must I do? (also, why is this so complicated?)

Update: Inspired by https://docs.continuum.io/anaconda/install I tried uninstalling like:

$ anaconda-clean -y
Backup directory: /Users/jonathan/.anaconda_backup/2017-04-24T160137

followed by the installation program again. The installation failed, anaconda is still supposed to be installed...

You can always create different versions of python in different folders. Simply specify the python version you want to use in a NEW folder. And then activate it.

conda create -n myProject python=3
source activate myProject

I know that you have uninstalled and reinstalled but you can create environments with other versions of Python. 

conda create --name py36 python=3.6 anaconda
source activate py36

This would create an environment with Python 3.6 and all of the default packages in Anaconda.

I ended up removing the anaconda directory and reinstalling.
