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.

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 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
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.
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.

The interpreter I use is
and it works in virtual environment. I have both anaconda and python interpreter installed in my system
But if I want to install something using pip for instance "Flask" then it happens
I am using Linux Mint 18.1 Serena"
And the way I tried to create the virtual environment is
Lastly there is no space in the directories where I tried to create virtual environment
Then I tried this link
Specifically the following commands
All those things didn't solve my problem and lastly I ended with the following errors each time I open my shell
Then I change my source of bashrc & bashrc-org to
virtualenv
export WORKON_HOME=~/virtualenvs
source /home/cryptosilicon/anaconda3/bin/python
Now get the following error
How do I correct the error and make the pip work inside virtual environment ?
I just solved (or at least found a work-around) for a similar problem.
I am using Linux Mint 18 and python 3.
I was trying to install a dependency inside a Python virtual environment using pip and it would fail (and actually pretty much mess up my whole virtual env).
The message was : "bad interpreter: No such file or directory".
But I noticed that the referenced path was actually truncated at the first space.
So I tested an virtual env in a folder for which path there is no space and it worked.
