How to completely remove and install again PIP on MacOS Sierra (10.x)?

Had PIP working normally until few days ago. Not sure how.

Your pip and Python installations are fine. What's wrong is your proxy configuration.

On OS X, both environment variables and the OS X network configuration can supply proxy information. First find out what configuration you have with:

python2.7 -c 'import urllib, pprint; pprint.pprint(urllib.getproxies())'

then look for any incorrect configuration in both your network settings (in the system configuration, check active networks for the proxies tab), and in your environment variables for *_proxy entries (http_proxy, https_proxy, etc.).

You can manually override proxies by setting one on the command line with the --proxy switch:

pip --proxy= install ...

Note the empty --proxy=; or you can set a specific proxy.

If you really did need to re-install your Python setup, you appear to have installed yours with Homebrew, so you can re-install it with brew install -f python@2.

Download Anaconda (or Miniconda), run it, and restart your terminal then start using environments. to create an environment type

conda create -n my_project_name python=3.6
conda activate my_project_name

Now do all the pip installs and conda installs you want. Your path is fixed. Pip is fixed. Go crazy.

Edit: Now that you've posted your full traceback it looks like you need to feed the proxy a username and password. Here is one way to do it.

pip install --proxy=https://user@mydomain:port somepackage
