Advice is welcome.
Thank you
I was able to reproduce the error and the reason seems to be the release of sqlalchemy 1.4 that introduces breaking changes. Airflow by default depends on the latest version of sqlalchemy, but cannot work with version 1.4. A workaround is to downgrade sqlalchem to a version < 1.4.0:
pipenv uninstall sqlalchemy
pipenv install 'sqlalchemy < 1.4.0'
When installing Airflow fresh:
pipenv install 'sqlalchemy < 1.4.0' apache-airflow
Please use below
pip install "apache-airflow[celery]==2.2.2" --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.2.2/constraints-3.6.txt"
It will definitely work.

But still same error. According to one comment of to this link (https://github.com/asweigart/pyautogui/issues/161) in github says it is not accessible remotely. I have tried sudo xhost + command but it gives me below error.

I'm on OS X 10.10.4 with Macports and Anaconda (condo 3.15.1).
During the process of building the robotic simulator ARGoS,
https://github.com/ilpincy/argos3
we ran into runtime 'qt' issues running the ARGoS examples.
[FATAL] Can't load library "/usr/local/lib/argos3/libargos3plugin_simulator_epuck.dylib" even after trying to add extensions for shared library (dylib) and module library (so):

I learned that cmake found 'qt' within Anaconda which had runtime problems.

Next, I installed qt4-mac:

How is this supposed to work?
I have zopeskel 2.21.2 in my virtualenv python and it works fine. Meanwhile, I also have the same version of zopeskel in my Plone buildout (located in ~/.buildout/eggs). However, it does not work. Running zopeskel --list throws the following error:
ImportError: cannot import name BasicNamespace
An advice from this link says to remove the egg. I have removed the egg as well as the cached package in ~/.buildout/cache/dist/ and ran buildout again. However, the problem persists. The funny thing is that the paster script in the same buildout is working.
My zopeskel section in buildout.cfg looks like below:
[zopeskel]
recipe = zc.recipe.egg
eggs =
ZopeSkel
Paste
PasteDeploy
PasteScript
zopeskel.dexterity
${instance:eggs}
Some package versions used in my buildout:
'/home/user/.buildout/eggs/Paste-1.7.5.1-py2.6.egg',

What could be wrong?
This usually happens you have ZopeSkel / Paster installed both locally (buildout) and in the global Python installation. Due to failures in Python process of managing site packages you end up with an incompatible combiation.
Solution:
