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'm having an issue using Python in my Mac Terminal Shell.
I used Python through Mac Terminal yesterday, but after I worked in Pycharm this morning, there seems to be an issue with my terminal.
Now when I simply write 'python', I receive this message:
zsh: no such file or directory: /usr/local/bin/python3.7
Any help, getting me back to using Python in my terminal would be appreciated!
Apparently the PATH of your S.O. It can't find the file to launch Python in your terminal so you could:
reinstall Python from the command line (zsh) and validate the "python" command again from the terminal
find the file associated with Python with commands like "find" and then modify the path of the PATH to the path where the Python launcher is
Pycharm has a tendency of changing your PATH after installation.
You have basically 3 options:
Option 1: Reinstall Python and use the path for both pycharm and zsh
I recommend this. It's a little bit of work, but you have a messy situation right now and completely kicking python off the system and then setting the PATH in your bash_profile and Pycharm is cleaner than the other options.
Uninstall Python. Make sure not to touch MacOS system Python.
Install Python
Path in Pycharm
Option 2: Find the path, Pycharm uses and set it in your bashprofile
See 1.3.
Option 3: Install Python and run it separately to the python path pycharm uses.
See 1.2
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 just installed my ubuntu on my PC then i installed python 3 & Vscode on my PC. but my VS Code didn't recognize the python3. maybe my vs code looking for my python. how to solve this?
In my VS Code when I compiled the class then the output:
python -u "/home/kisiniki/Documents/python/tempCodeRunnerFile.py"
/bin/sh: 1: python: not found
In my terminal already installed python 3.6.8.
First, try to see if you are able to run the same command in terminal.
python -u "/home/kisiniki/Documents/python/tempCodeRunnerFile.py"
If you are getting the same error, "python: not found", then likely python installation was not completely successful, you can either uninstall and reinstall or you can try to update PATH to contain the folder containing the python executable. See https://askubuntu.com/questions/637848/how-to-reset-python-path-to-usr-bin-python for more detail.
If you can run the command in terminal, then that means VS Code cannot find your installed python. See if you need to edit some settings in VS Code for it to know what python executable to run. See
https://code.visualstudio.com/docs/python/environments for more detail.
It's probably because you used the command python without having an activated virtual environment or not using python3 or python3.6. Try it with python3.6 and see if that fixes it. If it doesn't then Python isn't on your PATH.
I installed virtualenv and virtualenvwrapper successfully with pip. I'm running OSX Yosemite. I tested it when I first installed it (following instructions at newcoder.io)and it worked, but now it doesn't. I tried using the "source" command: source "/Library/Python/2.7/site-packages/virtualenv.sh" but I get the response "-bash: cd: python: No such file or directory."
Did I tweak something that knocked it offline? Thanks in advance for help!
OK, I got it, I think! I had been using "source" plus the path that the install program told me the program was in (see above) instead of the one that is recommended in similar questions. (OK, so I was overthinking this one). Anyway. I'm happy, I got it on my own!
