What could be the issue?

First - tkinter should be already installed on your Python if you have Windows or MacOS Info here
Second - for debian and linux - Tkinter isn't distributed through pip; if it didn't come pre-packaged with Python, you have to get it from elsewhere
For Python 3:
sudo apt-get install python3-tk
For Python 2.7
sudo apt-get install python-tk
As you can see names aren't equal to 'tkinter' so change it to your version
It'll work only if you are using yum
yum install tkinter
P.S. If for some reason you don't have it on MAC you can use commands for Debian and Linux in other syntax:
brew install python-tk
Name, as you can see, is still not 'tkinter'. You can change it in your 'requirements.txt' file if your .exe doesn't use pip

You should install
sudo apt-get install python-tk
This should solve your issue

Cannot get Twisted to work on a Mac

I am attempting to run the source code associated with the article at https://pawelmhm.github.io/python/websockets/2016/01/02/playing-with-websockets.html, but cannot get Twisted to work. I am using macOS High Sierra 10.13.5 and Python 3.6.4 (in a virtual environment).
To create the virtual environment I used:
python3 -m venv venv
. venv/bin/activate
where python3 is my system installed python 3.6.4:
$ which python3
/Library/Frameworks/Python.framework/Versions/3.6/bin/python3
I tried installing twisted using pip:
$ pip install twisted

Search on the web resulted in no useful resolution and attempts to use either easy_install or brew did not work too. Any suggestions are appreciated.

Thank you #9769953, that resolved the issue!
If anyone else searches for this issue (and for my future reference!), use:
python -m pip install twisted
I did have a virtual environment but apparently the python and pip combination was messing this up. Using python -m pip resolved the dependency issue.

How to uninstall dependencies introduced by a Python package installed with Pip?

I tried to install PyLint. When installing I saw the following:

Can I uninstall the packages mentioned here Installing collected packages: six, isort, mccabe, configparser, backports.functools-lru-cache, lazy-object-proxy, wrapt, astroid, pylint to restore to the previous state, or could the "Installing collected packages" refer to packages previously installed too?

There are two useful packages to deal with it.
Use the package pip-autoremove to uninstall package and its dependencies. You can also use pipdeptree to display a tree relationship of all installed packages.

pip will pretty explicitly tell you what exactly it does. If required packages are already installed, they won't be listed in the "successfully installed" list and it will say "requirement already satisfied" instead. If a dependency was upgraded during the installation, it will explicitly say that it found a previous version, that it uninstalled the previous version and that it installed a new version.
So, yes, in your case it does not look like it upgraded any old packages and purely installed new packages, so uninstalling all those should revert you to your previous state.

Installing twisted on python 3.5 and virtualenv using pip

when i run
pip install twisted
in the command line in windows, it starts installing packages until the flowing line comes up.
failed building wheel for twisted
pip then crashed soon after, saying it has failed the installation.
why is this ?
is there a way round it to install twisted?
my wheel version is 0.29, windows 10. twisted installs fine on python 2.7
thanks

I meet similar problem like yours.You can try to install the Twisted whit wheels
but at first,you should install the wheels
pip install wheels
then,download an appropriate version from this
website:http://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted
you can get xxxx.whl file
use
pip install xxxx/xxxxxx.whl
Finished!

Basically, that is not a programming question (I feel it might as well fit well into https://superuser.com/ or https://serverfault.com/).
Could you please provide a tad more information?
What OS are you running? What version?
For comparison, I'm running Debian GNU/Linux (testing), and
pip3 install twisted
performs fine:

I must admit, this install was done outside of virtualenv.
Did you try installing twisted outside your virtualenv?

Pip installation on virtual environment throwing error on versions of dependency package

We are trying to install OpenStack Services. We have created the virtual environment and installed Pip as well. Pip version is 8.1.1. Now when we try to install keystone we getting the error with dependency package as below:
