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 am getting this message on the VS Code that "Python is not installed. Please download and install python before using the extension."
There is also no *"Python Interpreter"* to select. When I click on it it shows it empty.
I do have Python and Python extension installed and I do have virtual environments set up in the Anaconda navigator but for some reason, I am not able to use them. I tried many ways like reinstalling the Python, Anaconda, and VS Code and also the Python extension for VS code but it's not solving the issue. What could be the reason?
I have attached a screenshot of the VS Code as well.
Pleae click here to see the screenshot
Thanks for your help.
I tried many methods but none worked. So then I removed this extension "Anaconda Extension Pack by Microsoft" and it solved the issue. So anyone facing the same issue might try uninstalling this extension.
I once faced similar problem and i found out that by default vs code looks for /usr/bin/python however in some cases on linux and mac the path is /usr/bin/python3 or 2 , so you can fix it by declaring python3 as default version .
open terminal and type the following command
sudo apt install python-is-python3
check the installation using -
python --version
it should give the output as 3.x.x
This is interpreter error. you have to click on interpreter error showing bottom right in vs code then you choose installed latest python version.
I reinstalled VS Code as is - not changing existing libraries etc - and now VS Code recognises Python/ paths again. :)
After updating to Windows 11 I think it just needed a refresh.
What did it for me was adding python to the environment variables (Windows).
Find python at "C:\Users\user\AppData\Local\Programs\Python\Python310\python.exe"
Copy this path
In the file explorer right click "This PC" and select properties
Click Advanced System Settings in the settings window that will open (blue link on the right)
Select Environment Variable -> New -> Add the copied python path
I´m new to python and using scripts in general but do need to use the script below to convert 6 images to equirectangular.
https://github.com/Xyene/cube2sphere
The python version I use is 3.7.4 (same as in Blender). Pip is installed and added blender.exe to PATH too. I´m trying to install for Windows but the instructions are too scarce and don´t understand exactly what to do with the "Finally, pip install cube2sphere" instruction. Is it run from Blender´s console or Windows Command Prompt? Do i need to reference the folder where the script is saved? Do i need to save the script in a specific folder? Do i have to run Command window from the folder where the script is and then pip install cube2sphere? Could anyone please give me more detailed instructions in order to use the script and then how am i supposed to make it work in Blender?
Thanks in advance
Is it run from Blender´s console or Windows Command Prompt? Do i need
to reference the folder where the script is saved?
You just need to include the the path of blender executable and then Run
pip install cube2sphere
on windows Console.

I'm trying to debug some python code using VS code. I'm getting the following error about a module that I am sure is installed.
Exception has occurred: ModuleNotFoundError
No module named 'SimpleITK'
File "C:\Users\Mido\Desktop\ProstateX-project\src\01-preprocessing\03_resample_nifti.py", line 8, in <module>
import SimpleITK as sitk
I installed the module using
sudo pip install SimpleITK
I know that it was installed because I was getting a similar error when I ran the code through the command line, and it was fixed by doing the above. I don't understand why VS code does not recognize that
After installing a new module via pip reloading vscode may work if vscode doesn't recognize it. To do this, make sure that the module is installed inside the virtual environment by creating and activating a virtualenv:
python3 -m venv env
source env/bin/activate
Make sure to use the correct way of installing a module with pip:
python3 -m pip install {new_module}
Replace the string "{new_module}" with your module name. After that, make sure to reload vscode by clicking Ctrl+Shift+P, and selecting Reload window.
Now vscode will know the new module and autocompletion works.
sudo pip install is most likely installing globally into a Python interpreter that is different than the one that you have selected in VS Code. Please select the Python interpreter you want to use and then install explicitly using that interpreter (if you're not using a virtual environment then use something like /path/to/python -m pip install SimpleITK, although I strongly recommend using a virtual environment and to not install packages globally).
In Mac, correctly selecting the Python Interpreter worked for me:
From within VS Code, select a Python 3 interpreter by opening the Command Palette (⇧⌘P), start typing the Python: Select Interpreter command to search, then select the command. You can also use the Select Python Environment option on the Status Bar if available (it may already show a selected interpreter, too):
No interpreter selected
The command presents a list of available interpreters that VS Code can find automatically, including virtual environments. If you don't see the desired interpreter, see Configuring Python environments.
Source :VS Code Select Interpreter
This error: your vscode use other python version. This solution change vscode use current python.
In terminal find current python version:
py --version
In vscode Press Ctrl+Shift+P then type:
Python: Select Interpreter
Select current python version
I ran into this problem with VSCode and resolved it by setting my Python interpreter within VSCode to the same as the one in my system path (type "echo %PATH%" on Windows and look for Python) via the process here: https://code.visualstudio.com/docs/python/python-tutorial#_select-a-python-interpreter
There are a lot of proposed answers that suggest changing the launch.json or the settings.json file. However, neither of these solutions worked for me.
My situation:
Is Python environment selected? yes
Does the Terminal recognize Python environment? yes
Can I run the Python code from the activated Terminal? yes
Does the code run w/o error when I use "Start Debugging"? yes
Does the code run when I click "Run Code"? no
The only solution that worked for me is to:
Open Windows Terminal (or cmd)
Activate environment: conda activate <environment_name>
Open Visual Studio Code from Terminal: code
Then, "Run Code" (#5) works without any issues.

"module not found error" in VS Code using Conda - l3d00m's answer
Faced similar issue and here is how I fixed it. Remember that there are multiple ways to run your code in VS code. And for each way you may end up with different interpreters and environments. For example:
1. Creating virtual env and installing libraries
In my case I opted into creating virtual environment and doing so outside of VS Code using command prompt:
python -m venv .plotting_test
Following that I activated it:
.plotting_test\Scripts\activate.bat
Following that I installed additional libraries:
python -m pip install matplotlib
Following that I made sure to see it was all installed ok:
python -m pip list
And I also checked where for current directory:
cd
2. Point VS Code & VS Code Code Runner to virtual environment
Opened vs code, closed previous workspaces, opened new folder, created test.py as I was starting new. Pressed ctrl + shift + p. Selected ```Python: Select Interpreter``:
Followed by + Enter interpreted path
Navigated to directory from last step from section 1. Found my virtual environment folder created in step one and pointed VS code to that version's python.exe in Scripts:
Verified I am pointed to such:
Saved as workspace so that I can create default workspace settings for this project:
In workspace settings files defined paths to my virtual environment created n step 1 for workspace interpreter & CODE RUNNER(!):
"settings": {
"python.defaultInterpreterPath": "C:/Users/yyguy/.plotting_test/Scripts/python.exe",
"code-runner.executorMap": {"python": "call C:/Users/yyguy/.plotting_test/Scripts/activate.bat && python -u"}
}
}
Reloaded window just to make sure (ctrl + shift + p) = "Developer: Reload Window"
Now run code and run python file should be execute under your specified envs:
Try running pip list in VS Code to check if the module is installed, next check if your python version is correct/supports that version of SimpleITK. It may be a problem with the python interpreter that you are using for VS Code (ie. the module may be installed on a different python instance than the one your VS Code is using)
Is Python environment selected?
Does the Terminal recognize the Python environment?
Can I run the Python code from the activated Terminal?
Does the code run w/o error when I use "Start Debugging"?
if the answer to the above is "yes."
Then,
Try running the Code using the option "Run python file in terminal" (in code runner extension). And assign a new shortcut for that for future use...
How to fix module not found error in Visual Studio code?
To Solve VSCode ModuleNotFoundError: No module named X Error Make sure you are running from the package folder (not from package/module ) if you want import module. calculations to work. You can also set the PYTHONPATH environment variable to the path to the package folder.
Once you have created a virtual environment, and installed your required packages in that environment, close VS code. For Windows platform, open command prompt and navigate to the folder where your virtual env folder is created. And then launch VS code from there using the command code .
For ex: My virtual env name is .imgenv, and its inside C:\py_stuff\projects
So, I navigate to C:\py_stuff\projects and then type code .
Now, your VS code should recognize the packages !
I just ran into the same issue. I found that if I selected all text before shift enter the script would compile as a file instead of as a single line.
I had the same problem. I bet you have a shebang statement at the top of your file.
If you do.
Visual Studios settings
Under "Code-runner->Code-runner: Respect Shebang" section or just do a search for "Code-runner: Respect Shebang"
Uncheck weather to respect Shebang to run code.
Now it will run under the virtual environment and find the modules that you installed using pip! :)
I struggled with this for a very long time, and had tried almost every other answer. I wasn't using pip, so that wasn't the issue. But still VS Code wasn't finding the modules that were installed in the Selected Interpreter.
Ultimately it came down to old conflicts that existed because I switched to miniconda, and VS Code was still looking for anaconda3.
I completely wiped VS Code and its associated files (cache, preference files, etc.) from my machine (some instructions), and installed a clean version.
This now syncs as expected with miniconda.
If you have different python versions installed, be sure you install module with right one.
python -m pip install <module>
or
python3 -m pip install <module>
Run your environment from a directory not in the users directory. I solved my problem running my environment from C:\Code\ProjectA\
I discovered my problem by running:
IMPORT os
Mycwd = os.getcwd()
PRINT(Mycwd)
.venv/Lib/SitePackages is the default directory where Vscode looks for Modules.
This directory is automatically created on creating .venv via the command Pallete.
External modules installed via pip are placed in this directory by default.
Place self created modules inside this folder manually.
For mac users
In the terminal check which python you are using by command which python. It will give you the path of the python interpreter path. After that type cmd shift P and type Python: Select interpreter.
After that select + Enter interpreter path and paste the path which you got after running the command which python.
I have a problem with the following command:
setup.py install.
I know it should work, I have tried it on a laptop but I don't have access to it at the moment. I need to complete a homework so I tried the same on my PC. And when I type the same command into cmd it just runs pyscripter as if I would use right click on setup.py and click edit with pyscripter. It does nothing else. I am sure that I am in the right folder in cmd.
My python version is 2.7 and my pyscripter version is v2.5.3. My OS is win7. I have tried to install other modules but I get the same response.
Has anyone encountered the same problem? I have searched the internet but I haven't found any answers to this problem.
Assuming that you installed Python 2.7 in the default folder i.e. c:\python27, then you can type:
c:\python27\python setup.py install
Wherever you installed it, you should append that path to your PATH variable (you'll need to log on as an admin to do that).
Do python setup.py install instead.
Windows is probably not set up to recognize .py files as executable.
Recently our class at school used all of the above programs. about a handful of students had trouble installing like you described. Fortunally I didnt not have this problen but I can suggest you use Administration priviledges.
Make sure you download the correct version.
Go to your download folder and look at the file you have downloaded (do this via my computer not from your web browser)
Right click on the file and then click run as an administrator
Here is an awesome site for windows binaries: http://www.lfd.uci.edu/~gohlke/pythonlibs/
If the library you need is there, just download and install like any other windows program...
