Not able to install django and use an existing django project

I am studying Django for the first time and everything was going well until the last day. Today when I tried opening my Django project, the terminal returns an error saying :-
Unable to create process using
'C:\Users\User1\AppData\Local\Programs\Python\Python310\python.exe manage.py runserver'
Thinking that it might be an issue with the virtual env, I tried checking my Python Interpreter to make sure I am currently in my venv.
Fortunately, I am currently using my venv but Pycharm indicates me to Install Python Packaging Tools.
I tried the link to install it but it notifies a Non Zero Exit Code(101) and Invalid Python SDK error.
Googling for the error asked me to check the path in Environment Variables where two are present -
C:\Users\User1\AppData\Local\Programs\Python\Python310\
C:\Users\User1\AppData\Local\Programs\Python\Python310\Scripts\
Recently I had added MingW Compiler to the path and that was it. I've never touched the path of Python.
I would like to mention that there are no errors in creating a new virtual envirnoment nor activating it. But things get worse when I try to pip install django. CMD tells that unable to create process.
Please help! I am actually stuck with my project.

Happy to say that I have fixed the issue.
Steps followed include :
Uninstalled Python,Deleted Path,Restarted my pc
Downloaded and Installed Python 3.10.2 from the official site.
Upgraded pip
Installed virtualenv using pip install virtualenv
Tested it creating env using - py -m venv "environment name"
pip install django works + started a project and the setup was successful.

First, try to run any python file (not in your project).
If it works, then the problem is with your django project or the env (try to create a new env and move your files to it).
At last, I think you should reinstall python; this will fix the problem I guess.

No python at '\python.exe'

No Python at 'C:\Users\~~~~\python.exe' error keeps coming out..
Even if I deleted my previous python and path, the file location is where I installed my previous python...
I want to use python in VS code and cmd on windows 10.
What I tried to fix it
deleted python 3.7 version and reinstalled python 3.6 version.
removed previous python 3.7 path and added python 3.6 version reinstalled to the Windows Path variable.
remove ';' on windows path variable.
put ';' on windows path variable.
delete and reinstall python on vscode Extensions

If you use venv, then look in that file:
pyvenv.cfg

The reason this happened to me was because I updated my python version. Therefore, the existing venv config was looking for an older python version. What I did was simply delete the existing virtual environment folder and created a new one.
To save all dependencies installed and transfer it into the new virtual environment, you can do the following:
pip freeze > requirements.txt to save dependencies into a text file
delete old venv folder
create new venv folder
pip install requirements.txt

First of all, make sure you have installed correct bit version for your version 32/64 bit...I would prefer to install python from Microsoft store...And restart VS Code...
If the error still exists try uninstalling and again installing Python extension for VS Code and restart VS Code...
And you can even try to install python in the path it is searching for... And also add the path to the environmental variable...
Hope this might solve your problem...as it has done mine.

I ran into this issue when having done the following:
I had Python 3.8 and 3.9 installed.
Installed Python 3.10.
Removed Python 3.9 and 3.9.
Set PATH property to contain the paths to Python 10 installation folder and its Scripts folder.
After this, Python stopped working from console and in IDE. When trying to add the Python interpreter to the IDE (Intellij IDEA) I realised there was no python.exe in Python 10 folder.
To fix this, I uninstalled Python 10 altogether and installed it again. It started to work.

Okay this should cover your issue. Firstly check whether it is installed
$ $(npm config get python)
or
npm --add-python-to-path='true' --debug install --global windows-build-tool
Moreover, do not forget to run your client interface as administrator.

Changing the virtualenv for the terminal in pycharm

I was postponing this question since i am not sure this is the right place to ask it. But i don't find a clear answer either.
I am running pycharm 2018.1.4, on windows and it seems that i can't change the virtual env that running in the terminal in pycharm. When i check the python version in the terminal i get version 2.7.3, for the project interpreter i have python 3.6 and for my run configurations i have the same 3.6 interpreter. There are no problems running the development server or anything like that, just in the terminal i can't run the manage.py script without getting following.
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?
I understand the error, i just dont get why it is using that virtuals env instead of the one configured as project interpreter. Anyone else stumbled upon this problem?

As far as i know, Pycharm's terminal is not bound to Project Interpreter and the IDE related features.
To make it work, you'll have to manually activate your virtualenv in the terminal.

It can be due to various reasons,
You can try the following command once the virtualenv is activated
python --version
If it shows python 2.7 as the version then it means in your system you have given python command to respond to the 2.7 version. Its more like a name tag.
Try python3 --version and it should give you back "Python 3.6".
If that's the case, then use python3 manage.py runserver and it should work perfectly

In Pycharm go to project setting,then go to project interpreter make sure that you have your required python virtual environment (which I think you did it already)
Under same selected environment, make sure that you have installed Django
Of course, if there is the dependency on Django, you can just type
pip install django

pycharm: says package not installed but server runs fine from terminal without any error

I have a Django project. I have installed django-extensions from terminal and added django-extensions to installed apps.
In pycharm i have selected the proper venv path for python interpreter
Now in pycharm when I run the server it says django-extension not found. But I can run the server from terminal without any errors.
In pycharm > settings > python interpreter : django-extensions is not shown.
I checked pip list in terminal and it shows django-extension package. Also I can see django-extension folder in site-packages. I am not able to understand what's the problem.
In Pycharm most of the pacakges are shown but only few are not shown

if you are using virtualenv, you need to install it proper way switching off virtualenv by using deactivate
and then installing package to your project therefore pycharm will read it in the project interprter folder

You need to set your project interpreter in pycharm.
It will be at File > settings > project interpreter
In above path you need to select your virtual environment (if not showing then add by clicking on '+' option)and apply then click on OK.
Now it won't show that error message.

1.Check if you are using a good virtual environment
If you have good env click on add icon on right side and add package manual

Sorry, there was no mistake with pycharm.
I have copied a complete virtualenv with my django project.
Later i found that in the /bin/activate
VIRTUAL_ENV="/path/to/original/virtualenv"
is still pointing to the folder from which i copied the project along with the vistualenv.
It should be
VIRTUAL_ENV="/path/to/present/virtualenv"
The packages are getting installed in the original folder. So now everything is working fine

Invalid Python SDK Error while using Python 3.4 on PyCharm

When I switch my PyCharm to use Python 3.4.3 and I am getting the error:
Invalid Python SDK
Also PyCharm does not automatically find the Python 3.4 interpreter for me, even though it is on the desired path /Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4. See the screenshot:
Despite this the interpreter does work. I am able to get correct output as expected, but code completion related to Python 3.4 is not working.
E.g. print("hello world!) still shows an error on the editor, but the console shows the correct output.

This also happened to me. I renamed a repository and then my virtual environment got stuck in the old path.
I grepped all configuration files and could not find any reference to the old one.
What finally solved the problem was to clear caches with the option File > Invalidate Caches / Restart...:

I had the same issue.
Try to comment/remove the PYTHONPATH variable in your ~/.bash_profile
#export PYTHONPATH=/usr/local/lib/python2.7/site-packages/
If it does not help it also may be useful to look in the idea.log for the errors:
/Users/username/Library/Logs/PyCharm40/idea.log
I had the following errors:
Your PYTHONPATH points to a site-packages dir for Python 2.x but you are running Python 3.x!
PYTHONPATH is currently: "/usr/local/lib/python2.7/site-packages/"
You should `unset PYTHONPATH` to fix this.

I go the same error message in Windows version of PyCharm after I re-installed Python (3.5) on a different location. The problem was that most of my existing virtual environments registered in PyCharm were still referencing the old installation of Python.
I resolved it by deleting these existing virtual environments and creating a new one. If deleting existing interpreters (in virtual environment) is not an option, you should be able to modify them instead in File | Settings | Project Interpreter

I got the same issue, when I updated Python (3.x) version via Home brew in MacOS.
Above answers didn't work for me. But with those, I realize that, it's an issue with linking the directories. I deleted ~/.virtualenvs folder and recreated all virtual envs.
$ ls -a ~/.virtualenvs
local-dev wdias-dev
$ rm -rf ~/.virtualenvs
$ which python3
/usr/local/bin/python3
$ mkvirtualenv local-dev --python=/usr/local/bin/python3
$ mkvirtualenv wdias-dev --python=/usr/local/bin/python3
Open the PyCharm again, and it works fine.

I couldn't get anything to work, so I cloned my conda env (see how), called it something else, and then set it in PyCharm to the new one.

For me, changing the paths in ~\venv\pyvenv.cfg made PyCharm recognize the new environment after bringing my projects to a new PC.

I had the same issue in Windows10. I was so frustrated, beacause everything seems looked OK. I've added PYTHONPATH, I've restarted Pycharm and deleted old virtualenv folders and created new... It did't work.
And at the end I have just opened Pycharm in an administrator mode and it works!

When creating a new project my interpreter was set to python 2.7 so I had to change that to python3 and everything works like a charm

I got the same problem with Pop OS 21.04 and Pycharm installed via Flatpack. So i remove it and installed via Snap and started working again.

I ended up having to install Python as an admin and make sure it installed to the C:\Program Files\Python310 folder. I think The option was to make sure it installed for all users. If I installed it under for user's appdata it wouldn't work.
Once I did that I was able to point pycharm to the C:\Program Files\Python310\ for the interpreter. Pretty annoying but finally got it working

I've solved it too. Uninstalled python 3.10, installed python 3.9. Changed the python interpreter to 3.9 through pycharm setting. Created a new virtual environment.
