Trying to clone and run a python web app from github locally

This is the web app I'm trying to clone: https://github.com/eddyharrington/Tendie-Tracker
Unfortunately, I'm not able to do it. I have followed all the steps provided. I'm a little confused with the last two steps.
Step 5: This is what I've typed
App variable
SECRET_KEY=randomText
DB variable
DATABASE_URL=postgres://{postgres}:{123}#{localhost}:{5432.0}/{tracker}
When I run the app, I get the following tracebacks.
File "app.py", line 6, in <module>
import tendie_dashboard
File "C:\Users\Maithri\Desktop\Mini Project\Tendie-Tracker-master\tendie_dashboard.py", line 3, in <module>
import tendie_budgets
File "C:\Users\Maithri\Desktop\Mini Project\Tendie-Tracker-master\tendie_budgets.py", line 3, in <module>
import tendie_categories
File "C:\Users\Maithri\Desktop\Mini Project\Tendie-Tracker-master\tendie_categories.py", line 10, in <module>
engine = create_engine(os.getenv("DATABASE_URL"))
File "C:\Users\Maithri\Desktop\Mini Project\Tendie-Tracker-master\env\lib\site-packages\sqlalchemy\engine\__init__.py", line 479, in create_engine
return strategy.create(*args, **kwargs)
File "C:\Users\Maithri\Desktop\Mini Project\Tendie-Tracker-master\env\lib\site-packages\sqlalchemy\engine\strategies.py", line 56, in create
plugins = u._instantiate_plugins(kwargs)
AttributeError: 'NoneType' object has no attribute '_instantiate_plugins'

Try putting the values without the curly braces. You should have something like,
DATABASE_URL=postgres://postgres:123#localhost:5432/tracker
Also, port numbers are integer values, not floats.

ImportError: cannot import name 'bytes_type' from 'oauthlib.common'

I am updating airflow from 1.10.5 to 1.10.10. I am getting the following error in webserver when using google OAuth

ImportError: cannot import name 'bytes_type' from 'oauthlib.common' (/home/airflow/.local/lib/python3.7/site-packages/oauthlib/common.py)
This error is because of the dependency mismatch. Airflow 1.10.10 is installing oauthlib==3.1.0 and Flask-OAuthlib==0.9.5 and in 3.1.0 version of oauthlib, there is no bytes_type while Flash-OAuthlib is expecting it to be there.
Considering that lepture has archived flask-oauthlib and created authlib, I see a PR in airflow from lepture about this change https://github.com/apache/airflow/pull/6140/files but it is not merged and marked stale by the bot
Has anyone faced this issue in Airflow 1.10.10? I have fixed this issue by changing the oauthlib version to 2.1.0 in requirement.txt

We faced the same issue and temporary fixed it by force upgrade flask_oauthlib to 0.9.6:
(When we wait for airflow fix its dependencies)
pip install flask_oauthlib==0.9.6

Importing requests in python gives error

I have a small python (2.7) script that works with several threads. One of the threads will read a global list and post an https post request for each one of the entries of this list.
For doing that I saw that the best way is to use python requests module. I have installed it with pip (no problem with that, it is placed in ...Python/2.7/site-packages/requests/...), but, when I import this module in my script, I get an error.
I have created another script with just one line (import requests) to reproduce the error, and I get this:
Traceback (most recent call last):
File "req.py", line 1, in <module>

Am I doing something wrong? Didn't I installed the module in the proper way?

it seems that you're having two modules with the same name array.py
rename your local array.py module to something more unique to resolve this.
take a look at this answer for more info on how to handle this issue and here to learn more on how python import system works.

ImportError: cannot import name normalize

I tried to use djangos i18n and therefor had to install gettext. Now I'm getting this awkward error any time I try to start my application:

from locale import normalize
ImportError: cannot import name normalize
The library locale.py is present and I can import it. Django 1.4 is running under Python 2.7.2+. Any Ideas?

I guess you have somewhere inside your project a folder locale with an __init__.py file in it.
Delete this file (you don't need it for translation to work) and you should be good to go.

pkg_resources.ExtractionError: Can't extract file(s) to egg cache
The following error occurred while trying to extract file(s) to the Python egg
cache:
[Errno 13] Permission denied: '/home/interworx/.python-eggs'
The Python egg cache directory is currently set to:
/home/interworx/.python-eggs
Perhaps your account does not have write access to this directory? You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.
I'm not sure if the "Module was already imported" error has to do with the "cannot extract PYTHON EGG" error.
In my WSGI I already have the following line os.environ['PYTHON_EGG_CACHE'] = rel('python-eggs') and I know for sure that works. Otherwise WSGI won't load my app. So I'm not sure what to do here.
Thanks!

When you get a message like "Perhaps your account does not have write access to this directory?" it's best to do a quick test. Try changing it to "/tmp" (which is writable by everyone) and see if things start working. If that fixes it, you can then identify a more appropriate directory and make sure that you (or the server) have write access to it.
Update: You are correct in choosing to tackle the earliest error message first. Here is a quick utility, Python Module Dump, that I wrote a few years ago for tracking down a mis-included module error. You might try inserting it at interesting points along your initialization code path and see if you can spot when the earlier import occurred.

There's a chance that your initial problem "Module was already imported" does in fact have to do with the permissions error you have going. Your best option would be to fix the permissions/ownership settings on the /home/interworx/.python-eggs directory (as stated by Peter Rowell above).
I came across this great little refresher on permissions today at the Google Code University. Wouldn't hurt to skim through this when you have some time: http://code.google.com/edu/tools101/linux/ownership_permissions.html
Just read the comments above here is my thoughts:
I think the problem is that the .wsgi file is not setting the environment variable in time. Can you please post your .wsgi file? Also, how are you grabbing the packages? Is it a script? Manually via pip?
