ImportError: cannot import name suppress
can anyone help to solve this issue?
The contextlib.suppress function supports from Python 3.4 but you are using Python 2.7. To solve this problem, upgrade your python version.
If this is useful for someone else, the solution for me (also using python 2.7) was:
pip uninstall attrs
pip uninstall queuelib
pip install queuelib==1.5.0
pip install attrs

I'm on Ubuntu 16.04 and python 2.7.
That Python3-only open() was added with version 3.0.6. Try earlier versions, 3.0.5 or 3.0.4:
pip install django-reversion==3.0.5
or
pip install django-reversion==3.0.4
Django 3 supports python versions 3.6 and above.
Here is the official Django 3.0 release notes
Using MacOS Sierra 10.12.6
Installing Django project dependencies from requirement.txt file
sudo pip install --user -r requirement.txt
I have looked over internet for the similar issues but none of them helped.
I even have tried uninstalling pyOpenSSL using command:
pip uninstall pyOpenSSL
even this command is giving an error:

At few place it is mentioned to use:

still getting same error.
even after deleting manually
> pyopenssl from python/2.7/site-packages/
and then reinstalling using command:
sudo pip install pyopenssl
it is not working, giving same error, (have also tried commands using --user flag)

You can install passlib module using pip
sudo pip install passlib
I am trying to install QSTK on my python 2.7.3. (on windows 10). During the installation, it seemed there was no problem and I did not face any errors. However, when I run the validation.py (here) to check it seems that QSTK.qstkstudu cannot be imported. Here is the error that I get while running validation.py:
QSTK is installed and can be imported
[...]
QSTK.qstkutil is installed and can be imported
File "C:\Python27\lib\site.py", line 372, in __call__
raise SystemExit(code)
SystemExit: Error : QSTK.qstkstudy can not be imported.
Does anyone have a clue what should I do?
The line in Validation.py which produces the error is:
import QSTK.qstkstudy.EventProfiler
If you try it directly in python, you can see what is missing. In my case it was tkinter.
>>> import QSTK.qstkstudy.EventProfiler

I am on Linux so I did
sudo apt-get python-tk
Google how to install python tkinter in Windows.
Good luck
I'm using python 3.3 and Windows XP(32x).

I am also using python 2.7, but I want to install setuptools for python 3.3.
I open my file with IDE and run it(because if you run code from cmd and you have both python2 and python3 it will run with python2 and iif you run it from IDE for python3 it will run in python3).
I really don't know if my explanation is true(because I don't have python2 on path), but I know that some files only work when you run it with IDE, and some only with cmd(or graphical).
