Before I get started please excuse the complete newbie question (request for dummy steps). I recently started learning Python and the Django framework using tools like Codecademy and Pluralsight and was hoping to dig into this by running Pinry (a Pinterest clone) using PyCharm, my IDE of choice for Python and work on modifying it with what I've learned so far to see what happens. Unfortunately, I download the latest version of Pinry and when I try to run it in PyCharm on my local machine I get all sorts of errors.
Here are the steps I take:
Python, Django, PyCharm are all installed and configured.
Download a new copy of Pinry and open the directory in PyCharm
Click on Run - Edit Configuration
Click on the + button to add a new configuration and check Run browse, select the Python interpreter (with Django) and click on Fix to enable Django support for the project
In the Project - Django settings, add the Django project root, settings and manage script
Finally hit alt/option + R and runserver to get the app started
At this point I would expect the package to run but instead I get the list of errors below.
Has anyone had any success in running Pinry in PyCharm without making any code modifications? I am just not sure if these are issues with the package or if its settings in PyCharm that need to be modified to make this work. Any insights?
THANK YOU!

Am trying to apply a migration to a new database but I keep getting this error, I have deleted all migration files in my old database and also files in the apps. when I tried applying migrations to a new database or running python manage.py runserver then I get this error..? I wonder what might be the problem. am using Django 3.1.1

Well! I was finally able to fix this problem by first uninstalling Django on my virtual env and then redo the installation, but the problem had still persisted, so I just followed my intuition by deleting the whole virtual env, I did the installation of virtualenv and then installed Django and it worked, perfectly. Thank you to all who had tried to help, I really appreciated your answers.
The auth.0013_user_following migration requires the 0003_contact migration which is missing.
Try removing all migrations from all apps and set a new database.
Based on the solution provided by Abubakari UmarblacKrussain Uma, I noticed that packages linked to my virtual environment file were missing/corrupted. When I checked it against my requirements.text file, I noticed that the Django package was replaced by django 2.2.27 (django lowercase), and an entry -jango 3.1.3 was added. I manually edited the requirements.txt file to remove the -jango 3.1.3 entry and replace the django 2.2.27 with Django 3.1.3 and reloaded the virtual environment from requirements.txt. This resolved the error. For good measure I re-generated the requirements.txt file for the virtual environment.
I'm trying to develop and deploy django app on azure web apps.
While following the tutorial on azure website, after cloning the basic project to my local machine (using git) and creating the virtual environment, I'm trying to run the createsuperuser commend, and getting this error:

It seems that your issue was similar with the other SO thread No translation file found for domain 'django' if you clone the Azure offical sample for Django like this. There is a *.mo line at the 49th line of .gitignore file. Please try to add the missing .mo file and do the createsupersuer operation again.
Hope it helps.

I have never had this problem before and my code always worked fine until I moved the project from one laptop to the other and can not execute it here.
Originaly, it worked fine but the system crashed and it is first time when I am trying to run the code on the new machine. I use virtualenv so I would expect everything to work smoothly but it does not ...
Is it a problem with python itself ?
It looks like you're running against the system version of python on the new laptop, rather than the virtualenv, so it is probably a different version. You can check this by looking at the version of Python on the virtualenv in the old laptop and the new laptop with python --version - I've seen this error happen in this case to people before.
Your best bet is to create a new virtualenv on the new laptop, and reinstall your packages (hopefully, you have a requirements.txt handy). If you need the same version of Python on the new laptop, you'll have to explore getting that version installed on your new laptop (do not overwrite the system version!), and pointing your virtualenv to the install. Good luck.
Like most other Mac/MySQL users with current versions of OS X, I went through the normal issues of getting Python, MySQL and MySQLdb (MySQL-Python) playing nicely together. That has been working for some time, but I'd like to use Aptana for debugging my work Django projects and when I try running either the debugger or running a project, I'm getting the dreaded "mach-o" error.
The interesting thing is that I've configured Aptana to use the same python I'm using (confirmed with a "which python" both within and outside of Aptana), and I've confirmed that the python that's being invoked by Aptana is 32-bit as it should be (same as system terminal reports). Also, when I use the Terminal in Aptana, using the interactive python shell I'm able to successfully 'import MySQLdb'. So I'm stumped.
Under arguments I'm adding this to program arguments per instructions:
runserver 8081 --noreload
But that shouldn't affect anything AFAIK. I'm at a loss of what to do next. Here is the error that Aptana is throwing when I try to launch:

Any ideas?
Take a look at: How do I force Python to be 32-bit on Snow Leopard and other 32-bit/64-bit questions on ways to configure Python to run in 32 bits (VERSIONER_PYTHON_PREFER_32_BIT environment variable seems a good choice).
Or maybe:
Troubles with PyDev and external libraries in OS X
I am running Python 2.6.1 on my computer, and just installed google App Engine.
As soon as I click on the App Engine Launcher, it gives an error dialog box and asks me to check the GoogleAppEngineLauncher.exe file for more details.
I have appended the log file below:
File "GoogleAppEngineLauncher.py", line 42, in <module>

From the file, I get the feeling that it's about giving the right proxy details.
I have checked up http://code.google.com/p/google-appengine-wx-launcher/issues/detail?id=17
and http://code.google.com/p/googleappengine/issues/detail?id=544.
It seems that it is about making some edits to some particular .py file so that I can enter my proxy settings, and username/password.
I have also come across few suggestions telling me to set the proxy in environment variables at the command prompt - but that hasn't worked. Any suggestions, please?
UPDATE:
I came across the following at nomagon dot com /?p=5 I am using it but unable to make sense out of the appcfg.py file
If your're not behind a proxy, then your ok to go! You can use the deploy button inside the App Engine Launcher, however if you're behind a proxy, you will need to set some variables
In a CMD window:
set HTTP_PROXY=<proxy>
set HTTPS_PROXY=<prox>
In a CMD window:
appcfg.py update <path to app>
