Both --allow-unverified and --allow-external take package name as an argument.

From pip help install:
--allow-external    Allow the installation of a package even if it
                             is externally hosted
--allow-unverified  Allow the installation of a package even if it 
                             is hosted in an insecure and unverifiable way

• --allow-external requires an argument (name of th external to allow).
• Same goes for --allow-unverified too .
• With pip install --allow-external pyodbc, you are allowing the external called pyodbc

• pip install --allow-external pyodbc pydodbc is what you need, first pyodbc allows that external, second one actually tells pip which package to install.

  From pip help install: --allow-external Allow the installation of a package even if it is externally hosted --allow-unverified Allow the installation of a package even if it is hosted in an insecure and unverifiable way

So your usage should be

pip install --allow-unverified --allow-external

or the little confusing:

pip install --allow-unverified --allow-external

DO NOT use --allow-all-external when you just want to allow one and not ALL. It kills the whole purpose of putting in the security check.
