pip installation error command 'python setup.py egg_info' failed with error code 1

Question

I am trying to install monkeytype on Ubuntu terminal using the command:

pip install monkeytype

but I'm getting an error saying:

Command "python setup.py egg_info" failed with error code 1

Here is the full log:

bash-4.3$ pip install monkeytype
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

With pip install, the real error is always hidden a little further up the log because pip runs the install routine of your packages.

In your case check for ERROR: Traceback, which says 'retype requires Python 3.6+'.

So, the installed package requires Python 3.6 but from an earlier error message we can deduce your pip runs python 2.7 (look for DEPRECATION: Python 2.7 )

So, fix the error by running the command with pip3 or python3 pip.

To verify which version of python is used, call pip -V.

Check the error list searching a line like 'WARNING: The wheel package is not available.' or something similar. Installing separately each missing package resolve the problems.
