Started to learn python a few weeks ago, i made and ran some basic files. all worked well.
At one point i uninstalled python and reinstalled it.
i continued making and running new files no problem.
now i am trying to go back to and run some of my old files and i am getting an error.
Error:Cannot run program "/Users/paulthomas/PycharmProjects/plotting/venv/bin/python" (in directory "/Users/paulthomas/PycharmProjects/plotting"): error=2, No such file or directory
In pycharm i open the folders and hover over the python file section and it says i have a symlink error. How can i fix it?
i have been using pipenv in my newer projects as they are django projects. But this project im trying to get to run is just a basic python project.
If you have reinstalled python, it is likely that the virtual env is linking to the wrong original python binaries.
You can either relink the files (by finding what they should have linked to, and relinking them) or if you have a requirements.txt file for the environment, delete and recreate the virtual env.
You can either do this through pycharm's environments system, or by using:
python3 -m venv <your environment name>
From your screenshot, your environment name is venv.
If the reinstalled python is a different version, it's likely safer to recreate the virtual env than to try linking things that may end up being inconsistent.

I'm working on a project in a python virtual environment, the project was started on a pc with python 3.8 installed and consequently python 3.8 was used in the virtual environment, or I had the need to continue the project on another pc, so I loaded all on GitHub, in the end I downloaded it to another PC with python 3.11 installed, the files are all there but when I try, inside the virtual environment, to open python by writing python or python3 in the terminal, it shows up this error: Python not found; Run with no arguments to install from the Microsoft Store or disable the link from Settings > Manage apps Run aliases. I then tried to see if it only showed up inside the virtual environment, but the same thing happens outside as well.
I tried to do various things among those suggested in other forums but they didn't work, the problem persists, I'm a bit lost, it's the first time this has happened to me.
Sorry to bother, maybe it's the simplest problem there is to solve but I don't know where to start

The problem is the different version of python on the two computers... the content of the pyvenv.cfg file must simply be changed which, when creating the virtual environment, is based on the installed version. Here you just need to change the path to reach the python.exe file installed on your computer and then change its version by inserting the correct one.
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.
I was running the Django project without any problems. Until I reinstalled Windows and then reinstalled vscode! Now that I am running the Django project, vscode shows the following error:
Error: no python at C:\Users\AccountName\AppData\Local\Programs\Python\Python38-32\python.exe
This might be occurs if the python directory still in the environment variables path list.
First remove python entry from the environment variables path if exists.
Also there will be a chance for virtual environments in your project. If the virtual environment is setup in the uninstalled python version then you will get the same error message.
So, remove the virtual environments which is created under the uninstalled python. It can be done by deleting the virtual environment folder from your system.
Edit pyvenv.cfg
home = C:\Users\UserName\AppData\Local\Programs\Python\Python38-32
include-system-site-packages = false
version = 3.8.3
When I edited this file after checking the file path on my computer, it worked for me.
Based on the information you provided, it is recommended that you check the Python environment variables.
Since the Windows system is reinstalled, the environment variables are restored to the default settings. Therefore, please add Python environment variables:
Or you can reinstall Python and check the "Add Python 3.8 to PATH" option, which will automatically add Python environment variables.
You could also refer to : Python environment variables.
It's very simple
Delete your dbsqite3 file from your project folder
Open your project in CMD
install virtual environment pip install virtaualenv
virtualenv .
\scripts\activate
python manage.py runserver
and play with your code
you shared.
This works for Pycharm, It did to me
From your projects folder, delete the 3 folders i.e. .ide,venv, and the third folder i think.. do not touch the projects or scripts you created. After wards, go to Pycharm and configure python interpreter again. This will now enable you to run yo scripts now with no prob
make sure to install virtualenv befor install python
check wheather django is installed (if your are using django framework).
pip install django
I've just setup a new environment for my project and uploaded a python repository including bin, lib and project folder. I'm pretty sure I did same previously and it worked without problem. Now when doing the same on an AWS environment I get the error
-bash: /projects/scrapy/bin/python2.7: cannot execute binary file. However when doing source /projects/scrapy/bin/activate it successfully activates the environment.
From what I understand, python should be able to execute without any issue no matter the environment ?
Any help or pointing to the right direction would be much appreciated!

No, the Python binary is tied to your specific OS and computer architecture. Python source code can usually be run on different machines (provided you didn't use OS-specific features), but that's only made possible by compiling a Python interpreter for the specific target environment first.
In other words, a Python binary compiled to run on macOS will not work on Linux.
All that source bin/activate achieves is that it configures your terminal setting to use the bin directory as the first directory on the PATH search path. This doesn't make bin/python work in another environment, it just means that both environments have a working shell interpreter that can run that script.
Create a new virtualenv with a Python binary compiled for Linux, and install the same packages there. Use Pipenv or a requirements.txt file to transfer the dependencies from Mac to Linux.
For example, using Pipenv you'd copy over the Pipfile and Pipfile.lock files to the other computer, then run pipenv install in the directory there and re-create the virtualenv and dependencies from those files.
I recommend you read up on Python development best practices in the The Hitchhiker’s Guide to Python; this includes such topics on how to manage an environment for a project.
I just copied my Flask project from one machine to another. I have same version of Python installed on both the machines. When I loaded the project in the new machine, it said my virtual environment is unavailable. So I initially tried to install it from requirements.txt file but it failed without any helpful error message.
So I deleted the virtual env in Visual Studio and tried to create another one. Now it complains that it cannot find any Python interpreters on my machine. I tried uninstall/reinstall Python but it didn't work. Also, the Python location is added in the PATH environment variable and all the modules in the requirements.txt file are downloaded from pip individually.
So the modules are installed, python is installed and the project is there but the virtual env won't setup because of the below reason. Any way that I can fix this ? This is PTVS15 and Python 3.6.1
Fixed it myself. I went ahead and added the environment manually by specifying the Python installation paths in the Add Environment tab. It took a while to detect the interpreter even in this way but it finally worked. I am now able to build my app.
