I used python and pandas so many times in VS Code but It causes a problem right know : problem
The terminal looks like this : terminal and I checked if matplotlib is installed or not but seems like it is installed matplotlib check. I don't know why this is happening but It was working until now.
The reason is that the python environment you are currently using in VS Code is different from the python environment used by the VS Code terminal.
Solution: Please close the currently used VS Code terminal (click the icon "Kill Terminal"), then select the python environment that has installed the required module at the bottom left of VS Code, and then use the shortcut key Ctrl+Shift+` to open the new VS Code terminal.
In addition, I noticed that you are using a powershell terminal. If you are using a virtual environment or conda environment, we need to activate this environment in the terminal (Usually it will automatically activate when a new terminal is opened.):
Check module:
Run:
Reference: Using Python environments in VS Code.
I was trying to download a GUI, but the terminal kept giving me this error:
Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.
I'm trying to install it using this command:
python -m pip install --upgrade pip setuptools virtualenv
Check your Python version and be sure it is installed on your machine
Check the path environment variable
Go to -> "start" and type "Manage App Execution Aliases". Go to it and turn off "Python"
I was having the same issue and I fixed it by using the below method.
Copy two paths of Python
C:\Users\Maninder\AppData\Local\Programs\Python\Python39
C:\Users\Maninder\AppData\Local\Programs\Python\Python39\Scripts
These are the paths where your Python interpreter is installed. Now add this path into your environmental
variable. Put this path into System variable, not in user variable. I was using user variable, so I was facing the issue.
I have a solution for you. Make sure you check the path mark during installation. Then you need to go to Manage App Execution Aliases.
Simply go to your search bar and search for Manage App Execution Aliases. You will find the attached screen and you need to turn off App Installers as you see on the screen. Also, see the path,,, follow Maninder's answer.
Then you are good to go! :)
I had the same issue. In Windows CMD, only: py --version, works.
I tried adding the path on System variables, and it didn't work. If you are using PyCharm as I do, try to run all commands from the IDE's terminal. It usually is on the side bar where the Run and the Console is. If it is not, go to: menu View → Tool Windows → Terminal. It worked just fine for me.
You need to download Python from https://python.org. When in the installation, be sure to check the option that adds Python to PATH.
I haven't gotten this error before and have been using Python a long time, and then suddenly it showed up. I think that it is a result of a Windows update designed to steer you to their store.
In any case: to remedy the problem, go to Settings → app execution aliases → and turn "off" Python. (What they tell you to do, in other words). This should resolve the problem.
If you have installed Python successfully with add python path, ticked on, and have added
C:\Users\<user>\AppData\Local\Programs\Python\Python39
C:\Users\<user>\AppData\Local\Programs\Python\Python39\Scripts
to the path into System variables and have turned off the "aliases" and they all didn't work, you can simply use python instead of python3 in your cmd command.
Check the Aliases for App Execution in Windows. Search for Alias App in your Windows toolbar to find the UI for this. Try turning off anything Python related.
Try adding the following to your "Path" environment variable:
C:\Users\Default\AppData\Local\Programs\Python\Python37
C:\Users\Default\AppData\Local\Programs\Python\Python37\Scripts
Replace Python37 with your own version.
I solved this problem for Visual Studio Code with just writing "python" in the console:
python
After that, Microsoft Store opens automatically with the Python app:
And I just click Get.
And it all work!
All the previous answers are correct, but in my case, I was getting this, because I was not passing the version...
The fix is passing the version:
py.exe -3 your_program
If you're on Windows, you may want to use the Python installer, in Windows Marketplace.
I faced the same error while using Anaconda and trying to link the Python executable path in the command prompt.
It got rectified by going to Settings → App execution aliases → and turning "off" Python. Then again I had to set the path for Python in Anaconda and was successful in executing "python --version" command.
The same thing happened to me even after trying all the above-mentioned steps.
I just restart my system and it was working fine. Do it and if still doesn't fix the issue then make sure you have checked "add python ( any version ) to PATH" before installing Python.
If none of the previous answers are working, you can check if you have the Python executable in your program files.
Go to C:\Program Files and check if you have the Python application. If not, go to the python download website here and download the .exe file.
While installing you must select "Custom install" and select the location as C:/Program Files.
Install it and it should work now from anywhere. This worked for me!
To sincerely resolve this issue, do the following:
Uninstall the Python instance and reinstall it. Note: Make sure you check
"Add variable PATH".
On the command line, type:
python -m pip install --upgrade pip setuptools virtualenv
I got this issue when I used Visual Studio Code as the IDE, and Anaconda as my Python compiler. And you don't need to close the "app alias" in settings, but copy your python.exe to python3.exe in your Anaconda folder.
That happened to me. So, to fix it, you have to follow the following steps:
Uninstall the Python version you already installed.
Go ahead and open the installation file to reinstall it again.
Before hitting Install Now, make sure to tick the box in front of Add Python to path.
Go ahead and complete the installation procedure as usual.
Steps for installing Python
The problem is more subtle than it seems.
For example, if you are using Visual Studio Code on the bottom left, you should see Python X.X.X xx-bit (the X is the version).
If you click in there you will see where the IDE is getting the python.exe from.
Locate that folder into your file explorer and then just follow the answer that is saying to change the environments variables.
So copy the path where python.exe is and add it to the Path variable and do the same where the Script folder is (it is in the same directory where the python.exe is).
Then of course make sure your IDE is using the right Python.
None of the answers here worked for me. I did this and the error went away.
For Windows 11 which I was using, I reran the python-3.10.5-amd64.exe file from my downloads directory and then chose to modify the installation.
Then I followed these easy steps.
Make sure the PIP component is checked before proceeding to install.
Then check 'Add Python to environment variables' if it's not checked already.
Proceed to Install.
At this point, your error will be solved
If you already have the Python executable on your machine and you are getting this error in Windows 10, search for the Python executable and copy its path then copy the path in system variables. It worked for me.
to check in windows
py --version
or restart your pc first then put htis command again
I was also facing this issue after installing python, while running command
python --version in command prompt , error as:
Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.
So, i too added
the path in environment variable as shown, and it worked:
I have a program coded in Python 2 that I need to run and I would like to run it in spyder via anaconda software.
The issue is that to run the program via the terminal I had to previously add in my system environment variables two new variables:
1) one folder in the computer where some required packages are
2) a variable with the ip address for the required license.
Although I have these variables define and the program runs without issues in the terminal. When I run it in spyder there is an error because it is not using those variables.
How can I fix this? I head something about anaconda creates virtual environments that is not loading those variables but I could not understand anything else. For example if I use pycharm, outside anaconda, it also works flawlessly
Thank you!

I believe Anaconda offers instructions on setting environment variables but that approach seemed complicated.
Setting an environment variable no longer seems to be an option in Spyder.
As a workaround Spyder does allow you to specify a startup file:
Preferences -> IPython Console -> Startup
In the startup file you just run something like:
import os
os.environ['my_var'] = 'my_value'
os.environ['test'] = 'test_value'
Every time you start a new ipython console this code will run.
There's an option in the Tools menu that let's you check/insert/update/remove the currently active environment variables in Spyder (pic for reference).
Spyder Environment Variables Feature
Edit: Regarding your PS question, when you install packages (through pip?) you are doing so through the currently active Python installation, which you can check by running
python -V
Therefore, if you intend to install a package in multiple installations, you need to use the corresponding package manager executable.
That dropdown menu is on Spyder 5.1.5
I have VSCode and I am trying to set up a virtual environment. First, I created all the venv properly. When I run in the Terminal is working and activated. However, it is not showing up in the VSCode. Make the matter worse, I can not change my interpreter at all. At first, I had python 2.7 and I could not change into python3 even though everything is set up properly. I fixed that problem with this setting "code-runner.executorMap.python": "python3 -u". And how I cannot change to another interpreter without the delete the setting. I am not sure what to do. Please help.
Thanks
Others have reported setting up virtual environments using VSCode. I suggest you set up your virtual environment using the terminal and activating the environment before starting VSCode. If you are using Anaconda Python this source will instruct you on setting up a virtual environment. For non-anaconda python, there are many pages for doing the same
To change the interpreter in VSCode, go to the View menu and select the Command Palette. When the command palette opens type python in the text box. This will cause commands with python in its name to be displayed. The first command (on my machine) is Python: Select interpreter. Select this and hit return. You will be given a list of python interpreters to choose from.
One of the projects that I work on in Python is pretty big and uses a lot of libraries.
I started developing it in Spyder then switched to VS Code.
I also use conda environment.
The problem is with VS Code only: when I open VS Code itself and try to run the project - I get all kinds of import errors.
However, if I open the conda terminal first and just type "code" in it and execute it - the VS Code opens, I can select my project and everything runs just fine, no errors.
In both cases the environment is the same, I did the Ctrl+Shift+P to select it, plus it shows as selected in the bottom left corner anyway. It's the default env.
How can I fix this so I don't have to start VS Code from conda terminal each time?
at the conda the modules are installed by default.
in vscode or any other of ides you have to install it manually.
open your terminal or cmd and type:
pip install module-name
I found what the problem was so I'll just leave it here in case it may happen to someone else.
My VS Code was using Powershell as the default shell, even though the input was right with the correct conda env selected (the base in my case), even with running
conda activate base
command to ensure it, it would still somehow mess up and complain about missing imports
So the solution was to set the default shell in VSC to regular Windows cmd.exe - that was the only needed change
