-bash: pylint: command not found

I have been trying to install pylint to be used on terminal, but have been unsuccessful in using it. The installation gets successful, but whenever I try to run pylint command, it returns the following error - 

-bash: pylint: command not found

I have tried using following commands - 

pip install pylint
python -m pip install pylint
sudo pip install pylint
sudo -H pip install pylint

I have uninstalled it, before trying each of the above command, but everytime I install it, the installation gets successful, but I am unable to use it on command line. I know it's something silly I am missing.

Here's the output I get on installation - 

My-Mac:Dev noob$ sudo -H pip install pylint

PS: I am using macOS Sierra 10.12.3 on a Macbook pro Late 2011, in case this is relevant.

I just copied the file path, then input that into the files to take me directly to where the scripts are stored then I copied all the scripts there and added them to the same folder where I have the code that I would like it to work on..

Summary: I moved the files downloaded on path.

For the very last comment in the response given by William Hammond on making this change permanent make sure to add the command to your ~/.bashrc, you'd find the hyperlink above a useful guide to get this done:

The issue is installed python executables aren't being added to your path. Our paths don't look exactly the same (probably because different python versions, I'm not sure) but mine is

host:~ williamhammond$ pip install pylint
Requirement already satisfied: pylint in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (2.3.1)
Requirement already satisfied: astroid<3,>=2.2.0 in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from pylint) (2.2.5)
Requirement already satisfied: isort<5,>=4.2.5 in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from pylint) (4.3.21)
Requirement already satisfied: mccabe<0.7,>=0.6 in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from pylint) (0.6.1)

Requirement already satisfied: six in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from astroid<3,>=2.2.0->pylint) (1.12.0)
Requirement already satisfied: typed-ast>=1.3.0; implementation_name == "cpython" in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from astroid<3,>=2.2.0->pylint) (1.4.0)
Requirement already satisfied: lazy-object-proxy in /Users/williamhammond/Library/Python/3.7/lib/python/site-packages (from astroid<3,>=2.2.0->pylint) (1.4.1)

I was seeing the same issues as you until I looked here

host:~ williamhammond$ ls /Users/williamhammond/Library/Python/3.7/bin/
dmypy           epylint         isort           mypy            pep8            pylint          pyreverse       stubgen         symilar

Once you add this to your path like

export PATH=$PATH:/Users/williamhammond/Library/Python/3.7/bin/

you should be able to use pylint. To make this change permanent make sure to add the command to your ~/.bashrc
