I had installed python 2.7 which was working fine till today. Suddenly it closed with an application error which it failed to capture and now everytime while running it its throwing the below mentioned error.
To give you a brief background the RAM memmory reahed to 95% which might have led to initial python crashing

twisted module got corrupted due to the crash. Reinstalled the module and its working again.
It seems that some third-party packages are the ones at fault here. Try re-installing them or uninstalling them completely. If you are working with twisted try going up to python3, it has great support and hopefully the latest install fixed corruption issues.

I'm trying to start a flask application, with flask run, (which was working fine before I installed Anaconda), and I'm getting the following stack trace

The Python version at the system level is 3.7.3
The Python version at venv level is 3.7.0
I've already tried to install contextvars, but it only upgraded an older version and did not fix the problem. In both system level and venv level contextvars requisite is already satisfied.
I'm running this on Windows 10.
Any idea on what can be causing this?
I have the same issue when using python 3.7.2 on Windows 7.
This is a known bug and should be resolved.
https://bugs.python.org/issue34691
Updating to python 3.7.3 resolved the issue (for me).
Try to update your venv level to 3.7.3

Does anyone know what is going on? It worked fine with the same file before reinstalling everything.
I ended up just downgrading Pyinstaller to 3.3 and that worked fine for my application.
pip install pyinstaller==3.3
Note: 3.0 also works as stated in my comment. I successfully tried 3.3 and am now using it because its newer.
As per Mike's own input, installing PyInstaller 3.0 will fix the problem. Just tried on Win7 Enterprise and it works just fine.
I'm trying to look around on this issue but so far nothing I've found has fixed it. I am not that familiar with Python and I'm working with someone else's script. I am on Windows 10 (64-bit).

The python module that you are trying to install will probably require you to compile it which makes the task much harder for a newbie.
Instead, I would recommend you to use a pure-python module like https://github.com/PyMySQL/PyMySQL -- which is much easier to install because you do not have to compile it.
Usually I recommend anyone that is trying to work with databases in Python to use SQLAlchemy, mainly because this allows you to use a single interface when you deal with the database, one that does not depends on the database-driver being used.
Read the answer from
python3 sqlalchemy pymysql connect string in order to get an idea about how to use pymysql via sqlalchemy.

tar xvf urllib3-1.16.tar.gz && cd urllib3-1.1
python setup.py install
I used pip uninstall on shapely and got an exception, which I did not save.
Since then every pip or easy install command will pop this exception :

Any ideas?
See this bug.
Off the top, pip uninstall shapely seems to be removing the top dlls from the Python installations. This is why you see the error on every pip command after.
