Could not find a working python interpreter. Please make sure one of the following is in your PATH: python python3 python3.8 python3.7 python2.7 python2
I installed python 3.10.4
Path is set in environment variables. Still not working.
How to set path:
Find the path to install Python on your computer. To do this, open the Windows search bar and type python.exe. Select the Open file location option.
Copy path of python folder.
To add Python To PATH In User Variables: Open My Computer\Properties\Advanced system settings\Advanced Environment Variables\Environment Variables.
In the User Variables menu, find a variable named Path. Then paste the path you copied earlier into the Variable Value option using Ctrl+v and click OK.
if you cannot find this variable, you may need to create it. To do this, click New. Then, in the variable name form, enter the path and paste your Python path into the variable value field.
6.You can also add Python to the PATH system variable. Although this is just an alternative and not needed if you have already added it to the Users variables.
To use the System Variables option, follow the steps highlighted above to copy the Python path and its script. Then go back to environment variables. Then, in the system variables segment, look for a variable named Path. Click this variable and click Edit.
It is working now. We have to set paths in both user variables and system variables. Then restart the PC.
If you have already set the path and can see only python and/or python 3 in the destination folder:
Type "python" in cmd. It will automatically take you to Windows Store, Install python 3.8 from there. Or you can externally install python 3.8 for latest Firebase plugin. This removes the error.
I've installed Python's latest version. However, when I write in command prompts
python --version
I get:
Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.
I tried downloading it directly from the Microsoft Store, however, the problem with that was that I could not very easily create a path for it and ran out of skills.
Anyways I'm trying to get Robot Framework to run just for fun, I'm a complete beginner as you can probably see. What should I do to fix this?
You have to add the path of Python to the environment of your system.

How to add Python to Windows PATH
There are few ways in which you can add Python to Windows PATH. In this guide, I’ll share with you two methods that you can use to add Python to Windows path:
Via the installation of a recent version of Python
Manual entry of the paths
But why would you want to add Python to Windows path in the first place?
Well, if you try to install a Python package using PIP for example, you may get the following error in the Windows Command Prompt:
‘pip’ is not recognized as an internal or external command, operable program or batch file
To overcome this error, you may apply any of the two methods described below.
Method 1: Install a Recent Version of Python
You can easily add Python to Windows path by downloading a recent version of Python, and then checking the box to Add Python to PATH during the installation.
Before you proceed, you may choose to uninstall your previous version of Python if needed.
In my case, the latest version of Python that was available to download was version 3.7.2.
In the Python installation box, just check the box to add Python to PATH as below:
How to add Python to Windows PATH
Finish the installation, and you should be good to go.
Alternatively, you may manually add the paths into the Environment variables.
Method 2: Manually add Python to Windows Path
If you wish to stick with your previous version of Python, you may apply the steps below to manually add Python to Windows path.
Note that I’ll be using Windows 10 to demonstrate the steps, but similar principles would apply for previous versions of Windows.
Step 1: Navigate to the Windows Environment Variables screen
To navigate to the Windows Environment Variables screen, where you can add/edit your paths, simply right click on the ‘This PC‘ icon. Then, select ‘Properties.’
This PC - Windows 10
Next, click on the ‘Advanced system settings‘
Advanced system settings
Finally, click on the ‘Environment Variables…‘
Environment variables
That should take you to the Environment Variables screen, where you can add/edit your paths.
Click on ‘New…‘ to add the ‘Path’ variable (note that if your ‘Path’ variable already exists, then click on ‘Edit…’ instead):
add Python to path
You should then see the following box, which will allow you to add/edit variables:
New User Variable
Before you type any values, you’ll need to locate the relevant Python paths. The paths that you’ll need to get are:
The Python application path, which is the folder where you originally installed Python; and
The Python Scripts path. The Scripts folder should be located within the Python application path.
Here is how my Python application path looks like:
Python application path
And this is how my Python Scripts path looks like:
Python Scripts path
Now let’s fill the New User Variable box that you saw earlier:
New User Variable
For the Variable name, type ‘Path‘.
For the Variable value, copy the full Python application path, then use semicolon (as highlighted in yellow below), and finally copy the Python Scripts path.
This is how my Variable value looks like:
C:\Users\Ron\AppData\Local\Programs\Python\Python37-32;C:\Users\Ron\AppData\Local\Programs\Python\Python37-32\Scripts
Put all the values together in the New User Variable box:
New User Variable - Windows 10
Press ‘OK’ and you would then see your new Python Path under the ‘User variables’ section. Don’t forget to press ‘OK’ again so that the changes will get implemented.
How to add Python to Windows PATH
That’s it! You just added Python to the Windows Path.
You’ll now be able to install Python packages easily, by opening the Windows Command Prompt and then typing:
pip install package name
For example, to install the pandas package, simply type ‘pip install pandas’ and then press Enter:
How to add Python to Windows PATH
Similarly, you may upgrade PIP by typing the following command:
python -m pip install --upgrade pip
Today when I tried to run simple code on Sublime Text 3, the following message appeared:
Python was not found but can be installed from the Microsoft Store: https://go.microsoft.com/fwlink?linkID=2082640
And when I type Python in CMD, it opens the Windows Store for me to download Python 3.7. This problem started today for no good reason. I didn't change or download anything about Python and already tried reinstalling Python, and the Path environment variable is correct.
Use the Windows search bar to find "Manage app execution aliases". There should be two aliases for Python. Unselect them, and this will allow the usual Python aliases "python" and "python3". See the image below.
I think we have this problem when installing Python because in a new Windows installation the aliases are in the ON position as in image below. When turned on, Windows puts an empty or fake file named python.exe and python3.exe in the directory named %USERPROFILE%\AppData\Local\Microsoft\WindowsApps. This is the alias.
Then Microsoft put that directory at the top of the list in the "Path" environment variables.
When you enter "python" in cmd, it searches the directories listed in your "Path" environment variables page from top to bottom. So if you installed Python after a new Windows 10 install then get redirected to the Windows Store, it's because there are two python.exe's: The alias in the App Execution Alias page, and the real one wherever you installed Python. But cmd finds the App execution, alias python.exe, first because that directory is at the top of the Path.
I think the easiest solution is to just check the python.exe and python3.exe to OFF as I suggested before, which deletes the fake EXE file files. Based on this Microsoft Devblog, they stated they created this system partially for new Python users, specifically kids learning Python in school that had trouble installing it.
Creating this alias was to help kids just starting Python to install it and focus on learning to code. I think Windows probably deletes those aliases if you install Python from the Windows App Store. We are noticing that they do not get deleted if you manually install from another source.
(Also, the empty/fake python.exe is not really empty. It says 0 KB in the screenshot, but entering "start ms-windows-store:" in cmd opens the Windows App Store, so it probably just has a line with that and a way to direct it to the Python page.)
Finally, as Chipjust suggested, you can create a new alias for Python using something like DOSKEY as explained in this article for example:
How to set aliases for the command prompt in Windows
The main problem here is that the order in the path calls the windows from top to bottom, and that there is python.exe in %USERPROFILE%\AppData\Local\Microsoft\WindowsApps which is called first if there are no other python.exes in the PATH above that line.
To ensure that the correct python.exe is called, add the Python interpreter installation folder (containing python.exe) to the PATH, above %USERPROFILE%\AppData\Local\Microsoft\WindowsApps
Here is an example:
To get to this location, click "Start" → start typing "Env" → Select "Edit the system environment variables" → "Environment variables" button → Select the entry for "Path" in the upper list → Click "Edit".
Python components should be at the top, as in step 5. If not, move them up by pressing the button in step 6.
If the Python interpreter is already installed, then go to Apps & features from settings, select Python, and then select modify.
Again select modify and select Next:
Then this window will appear:
Select "add Python to environment variable" and click on the install button. Then again go to apps & features, click modify and click Repair.
Now go to CMD and type Python.
Problem solved.
This is a PowerShell script that does the magic.
Remove-Item $env:USERPROFILE\AppData\Local\Microsoft\WindowsApps\python*.exe
I had problems with this as well, where Windows didn't recognize Python or Anaconda in a double click or cmd (command) prompt.
Problem: unable to import libraries in "python" cmd in Windows. Instead the Windows "python" cmd took users somewhere they don't want to go.
Problem Cause: In Windows "Environmental Variables", Windows adds a python.exe and python3.exe (I don't know where these link to) in the "%USERPROFILE%\AppData\Local\Microsoft\WindowsApps" directory.
Solution: I tried deleting the python*.exe files in the WindowsApp directory, but Windows wouldn't allow it, so I opened a command prompt in the "%USERPROFILE%\AppData\Local\Microsoft\WindowsApps" directory and typed:
del python.exe
del python3.exe
Then I created an environment variable linking to the installed Python interpreter link. In my case, it was C:\Anaconda3; C:\Anaconda3\Scripts, and some others for good measure.
Because this is a common issue and this appears to be the canonical question, I want to try to give a complete overview of The Python 3.7 Windows Store Fiasco (TM).
Why is it possible for this to happen?
A convergence of two things: the previous introduction of the Python Launcher for Windows in 2011 (hereafter py), and a Windows 10 update in May 2019 that was apparently intended to make installing Python easier for Windows users.
Oops. Turns out that installation path isn't great; it bypasses the "lengthy" setup wizard... which contains some options that some users find very useful. It caused other issues, too. Not to mention that it just works in slightly non-standard ways, has limitations on file system access because it's a Store app, initially couldn't itself be launched by py....
Okay, but why do those factors result in the problem?
Since the introduction of py, by default, Windows Python installers do not add the new Python install to the PATH. Why? Because the entire point of py is that it uses its own logic to find a Python installation, based on some combination of command-line switches and possibly the source file's own shebang line. Now your source files can be associated with py instead of any particular python.exe, and you can get Linux-like behaviour when double-clicking a file. Meanwhile, by running py at the command line, you have easy access to whatever you need, and you don't have to think about which version of Python was installed most recently. So there's seemingly no good reason to put any of those Python installations on the PATH. It only risks confusing you when, for example, the most recently installed version isn't the most up-to-date one. Right?
In the update, Windows 10 put a "python.exe" into a Windows Apps-related folder, which is a wrapper app to open a Microsoft Store link. The idea is that it's on the PATH, but way near the end; so if you have an installed Python, it gets used, and otherwise the wrapper is invoked and helpfully prompts you to install Python - so that you can actually run that random, totally trusted .py file your friend sent you on Discord.
And it would work perfectly, if your installed Python were on the PATH.
Oops.
(But, you know, py had been introduced around 8 years prior. You'd think someone at Microsoft would have been aware of the potential issue. Maybe instead of a special shortcut link, they could have made an actual script that checks for the presence of C:\Windows\py.exe or something.)
So what are my options?
You can check the option to add new Python versions to the PATH when you install them, and deal with the fact that python at the command line means a specific one of them. If you need to change that, you can manually tweak your PATH variable.
You can just manually tweak the PATH variable after the fact. (or "Modify" a Python installation to fix it.) This is covered in several other answers.
Independently of that, you can disable the wrappers, as shown in the top answer. You should probably do this anyway; seeing python fail at the command line is less aggravating than dealing with a random GUI window popping up and offering to install something for you, especially when you know you have it already.
If you want to keep the PATH empty, consider using virtual environments for your projects. Whenever a virtual environment is active, the PATH is temporarily modified such that python means the Python installation of that environment. It's quite convenient, really.
You might be able to tell your IDEs to use py instead of a specific Python installation, and it might even be helpful to do so. I don't know. I don't use one.
As a person who does Python development in Sublime Text, I know you said the Python interpreter path was correct, but when you install the Python interpreter make sure to tick the option to add Python to PATH.
I had the same issue back in the day till I did this.
You can manually add Python to the Windows path by doing this:
Start the Run box and enter sysdm.cpl
Go to the Advanced tab and click the Environment Variables button
Now you’ll need to locate the relevant Python paths
Here is how a Python application path looks like:
And this is how a Python Scripts path looks like:
Select the Path variable, press edit and add both paths (Python application and Python Scripts)
If it doesn't show, press new instead of edit and fill the New User Variable box
This is how my Variable value looks like:
C:\Users\Ron\AppData\Local\Programs\Python\Python37-32;C:\Users\Ron\AppData\Local\Programs\Python\Python37-32\Scripts
That’s it! You just added Python to the Windows Path.

So, I had the same problem.
My answer was to add python to PATH not only for User variables, it was there, but also for System variables. And now everything works.
So, I've got the same problem in VENV.
I solved it by typing >> python**.exe**
But to add every time .exe a little bit nervous.
Also try to type python.exe in cmd.
This is an additional note for anyone using pyenv-win: after turning off the application execution aliases, run pyenv rehash. You may also need to close/reopen your CMD or PowerShell window.
I have put together a powershell snippet, which reorders WindowsApps and Python folder so that Python is first. Run this as Admin:
$appsFld="$env:USERPROFILE\AppData\Local\Microsoft\WindowsApps";
$pyPath=(Resolve-Path "$env:USERPROFILE\AppData\Local\Programs\Python\Python*\")
$Env:Path = (($Env:Path.Split(';') | Where-Object { $_ -ne "$appsFld" }) -join ';');
$Env:Path = (($Env:Path.Split(';') | Where-Object { $_ -ne "$pyPath" }) -join ';');
$Env:Path += ";$pyPath";
$Env:Path +=";$appsFld";
[Environment]::SetEnvironmentVariable("PATH", "$Env:Path", "Machine")
Then I can run python just fine:
> python
Python 3.10.7 (tags/v3.10.7:6cc6b13, Sep 5 2022, 14:08:36) [MSC v.1933 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> quit
Adding a bit to the question. Even when I typed pip freeze, it wasn't showing anything.
Here's what I did:
There were multiple instances for the Python application in /AppData/Local/Microsoft/WindowApps.
I deleted those and then it worked.
I want to switch over to VS Code. I did the following to enable python with the packages I typically use, including a local utilities package on this machine:
Searched for the setting python.pythonPath and made it PycharmProjects/Project/venv/Scripts/python.exe for both this workspace and for my user
Changed my Windows user PYTHONPATH to PycharmProjects/Project/venv/Scripts/python.exe
Tried PycharmProjects/python.exe;local-utilities-directory
However, the folder I'm trying to manually set won't show up as a possible option when I click on my interpreter in the bottom right. Instead I'm defaulting to an older interpreter that doesn't have all the packages I've amassed.
While I can access some packages, while trying to pull in my personal utilities library, pip fails (the term pip is not recognized...)
I see that there are a few other ways to change the python path, however, to my understanding, whether you do it in a .json or via the IDE UI, shouldn't actually matter.
Any help would be appreciated.
So, I think I messed things up by offering too many paths.
I had to double check that the exact same path showed up first in:
Work setting pythonPath
User setting pythonPath
Windows profile path
Windows profile PYTHONPATH
I deleted the other "backup" paths, and it ended up working.
I am trying to access Python through a Windows command prompt, but am at an office and cannot add an Environment Variable. So, I cant follow the advice provided here. Thus, I added a User Environment Variable through User Accounts and use Variable:python and Value: C:\Python33. When I do a Windows Run check on %python% I reach the required Python33 folder. However, when I type python -Version in the command prompt I get the error 'python' is not recognized as an internal or external command, operable program or batch file. I am not sure how to proceed.
Run Python from the command prompt and include the full path to python.exe. For example to get the version:
C:\Python33\python.exe --version
When you run a script you specify the path to the script if you're not in the directory where the script is located. For example, if your script is in C:\scripts and is called my_script.py:
C:\Python33\python.exe C:\scripts\my_script.py
Instead of setting environment variables, you can use the whole path, like Neo wrote e.g.:
C:\Python33\python.exe yourPythonScript.py
Remove any environment variables you have added.
C:\Python33\python.exe pyscript.py should work.
I once Had a similar problem, but i couldnt find any solution, not even adding the path to the python folder was working.
Then I opened Python and clicked in File, then browser path, and I found that I had another folder that contained the real Python folder, not the default one. Maybe it could work for you too.
