Python – Can I install Anaconda on MacOS to overwrite a corrupted Anaconda installation?

I

want to run jupyter notebooks, but the Anaconda environment for the Mac I’m using is a mess. The old owner uninstalled some packages I wanted to use – jupyter notebook, pyzmq, etc. I wanted to use jupyter notebooks, but after I tried manually reinstalling these packages using:

pip install jupyter
pip install pyzmq

An error occurred at runtime: jupyter notebook:

Traceback (most recent call last):
  File "//anaconda/bin/jupyter-notebook", line 4, in <module> import notebook.notebookapp
  File "//anaconda/lib/python2.7/site-packages/notebook/notebookapp.py", line 40, in <module> ioloop.install()
  File "//anaconda/lib/python2.7/site-packages/zmq/eventloop/ioloop.py", line 210, in install assert (not ioloop. IOLoop.initialized()) or \
AttributeError: type object 'IOLoop' has no attribute 'initialized'

Can I reinstall Anaconda

again (or do I have to somehow uninstall Anaconda and install it on a clean system)?

This answers in this post will address your issue

However, if you want to start over, I recommend removing anaconda completely and then installing miniconda.

Once miniconda is installed, you can use:
Conda installs Jupyter
Conda installs pyzmq
Conda installs WHATEVER_PACKAGE
