I've built a small project on my system.
After building the project, I put it on a USB drive, and copied to another system.
When I run the project, how can it detect if django is installed in the system or if the system has all of the the requirements for the project?
For example, I made a blog example project on a laptop, then copied that project(blog) onto a USB drive and then I copied that project(blog) to my own system. After copying, I tried to run the project. If django is installed then the project runs successfully. But when django is not installed it gives an error in the terminal.
How can the program detect if the required (Django/Python) is installed or not?
Simply the module won't be found when you try to run your project.
You can run 'python' in your command line and try to 'import django' if it returns an error then django isn't found it means that django isn't installed on the current machine.
When you will try to run your Django project you will get ImportError and i think it is the detection that django is installed or not.
ImportError: No module named django
Into your project you can write a new management command to check that in system django is installed or not.
and you can run like .
python manage.py is_django_installed
even you can customize your runserver/migrate/syncdb management command to check that django is installed or not .

I am currently trying to deploy a Python/Django app to Heroku. The build was successful however, I am attempting make a migration to an established postgresql database to connect it to Heroku remote.
When I run:
heroku run python manage.py migrate
I get the following error:
ImportError(
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
The Django environment is currently activated in my terminal screen.
I ran python to get the version type then ran print(sys.path which showed the Django environment listed. Just for giggles I ran pip install django once again, where a message stating requirement already satisfied came up.
So it looks like django is installed, my virtual environment is working, but I cannot make the migration for Heroku...
Any advice appreciated.
After I tried to deploy my Django website on Azure, I got an error saying:
ModuleNotFoundError: No module named 'django'
I added a requirements.txt in the root directory of my Django project, am I missing anything else? I've tried to install Django from Kudu BASH but it gets stuck on "Cleaning Up".
Here is the full error: https://pastebin.com/z5xxqM08
I built the site using Django-2.2 and Python 3.6.8.
Just summarized as an answer for other people. According to your error information, I can see that you tried to deploy your Django app to Azure WebApp on Linux based on Docker. So there are two offical documents will help as below.
Quickstart: Create a Python app in Azure App Service on Linux
Configure a Linux Python app for Azure App Service
The error ModuleNotFoundError: No module named 'django' indicated that there is not django package installed on the container of Azure Linux WebApp.
Due to the content of Container characteristics of #2 document above as below,
To install additional packages, such as Django, create a requirements.txt file in the root of your project using pip freeze > requirements.txt. Then, publish your project to App Service using Git deployment, which automatically runs pip install -r requirements.txt in the container to install your app's dependencies.
So the possible reason is the requirements.txt file not in the corrent path of your project or container after deployed, which path should be /home/site/wwwroot/requirements.txt on the container or the root of your project like the offical sample Azure-Samples/djangoapp on GitHub.
I had the same problem. requirements.txt was in my repository, but randomly I started getting the same error ModuleNotFoundError: No module named 'django' after changing a setting or restarting the service or something. Nothing I could do, change the setting, or reboot repeatedly fixed it. Finally what worked for me was this:
Make a small change to the code and commit it, and push it up to the app service.
This fixed it for me. It has happened a couple times now and every time this solution has worked for me. It seems like the App Service sometimes gets in this state and needs to be jostled with this trick?
Can I run django server ingnore part of the project in Django?
I have a Django project with several apps, and one of the apps is need to import openstacksdk(because it relay on many linux libs, in Mac env is very troublesome ), so I must work in the Linux operate system. but now I have done that app which must import openstacksdk.
Now I cloned the project from Linux to my mac, there will report error which related to openstacksdk.
This is the directory of my project:
So, is there a way only to debug the apps that do not contain the openstacksdk-related app?
You can use Vagrant or some other virtual machine to run Linux on your Mac. I am working on a Django project in Windows and another developer is using Linux and another is using Mac and we can all run the same code because we have identical environments installed inside Vagrant. Takes a bit of work to set up initially, but it should solve the problem. Make sure to install an OS in Vagrant that is close to (identical isn't always possible, unfortunately) the production server OS.
I need to set up a Jenkins server to build a python project. But I can't find any good tutorials online to do this, most of what I see uses pip, but our project simply works on
python.exe setup.py build
I've tried running it as a Windows Batch file setting it up through the configure options in Jenkins, where I enter the above line in the box provided, but the build fails.
When I try to run this I get a build error telling me there is no cmd file or program in my project's workspace. But it seems to me that cmd would be a program inherent to Jenkins itself in this case.
What's the best way to go about setting up Jenkins to build a python project using setup.py?
Really i used jenkins to test Java EE project and i don't khnow if it will be the same principle or not ,
so i downloaded the jenkins.war from the website and i deployed it on my jboss server and I reached it via an url on the browser : http://localhost:serverport/jenkins the i created a job and i select the server & jdk & maven & the location of my project in workspace then i make a run to build the project.
I am sorry if you find that my subject is far from your demand but I tried to give you a visibility onto my use.
I relaized I did something stupid and forgot that my coworker had set it up on a UNIX server, so I should have been using the shell instead of Windows Batch. Once I changed that and installed the python plugin, I got it to build fine.
Finally made the switch from Windows to Linux (Ubuntu). I am teaching myself Python + Django.
GOAL: I want to setup a local development environment where I can build a django application and run it locally before deploying it live online.
SO FAR: Python comes installed with Linux. Gedit does also. Ok great. After that I am lost.
I am not sure how to proceed. I am a total Linux noob. I am guessing I need apache running, mysql running, and django to run. I don't know how to setup these things to run or how to set the proper directories or what I need to link to what... really I am not even sure what the right questions are to ask.
Quick answer:
Just install django via their documentation, and you will not even need apache running as it will run its own server. You can use sqlite as a db and you won't even have to worry about mysql. This is if your goal is to learn django and get things running asap.
Otherwise, if you want to take the full route, you'll need to start learning a lot more (which isn't a bad thing). I'd say take a look at some of the slicehost guides for setting up apache, mysql in ubuntu:
http://articles.slicehost.com/2010/5/19/installing-apache-on-ubuntu
http://articles.slicehost.com/2011/3/10/installing-mysql-server-on-ubuntu
And then pick up with just installing django and going from there. The django tutorial is awesome. There's plenty of other documentation out there on the web & tutorials for setting up dev environments.
Assuming you have python
You can install pip:
easy_install pip
From now you can use pip to install your python libraries for example to install django
pip install django
For development I would prefer pydev, it has a support for django with the power of eclipse.
