I have Windows 10 on my computer and when I use the cmd and check python --version, I get python 3.8.2. But when I try to find the path for it, I am unable to find it through searching on my PC in hidden files as well as through start menu. I don't seem to have a python 3.8 folder on my machine. Anybody have any ideas how to find it?
If you can open the python interpreter sys.executable will give you the path.
import sys
print(sys.executable)
Python paths in Windows can get a little strange. I prefer to use the official packages from python.org. And I use the "install for all users" option. Finally, I prefer to have my Python installs one level below C: drive, i.e. C:\Python37.
If you do not use the "install for all users" option, the Python directory gets buried in C:\Users\xxx\xxx somewhere. And some IDEs (I'm looking at you PyCharm) like to install everything in virtual environments (venv).
#moeen.n answer of sys.executable is probably the easiest to find out where your install is.
If you're using cmd (ie Command Prompt), and typing python works, then you can get the path for it by doing where python. It will list all the pythons it finds, but the first one is what it'll be using.

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 used IDLE for some time, then for a class they told us to download Anaconda, which I ended up not using, but still downloaded it anyway.
I uninstalled anaconda and deleted all the files from my CPU and started using IDLE again. I now can't import a module to IDLE because it can't find it. I think anaconda messed up the python path, but I don't know how to change it so I can import modules back to python.
How can I determine what the python path is and how can I change it so when I download modules I can import them to IDLE again?
I am running OsX 10.10.5 and Python 2.7.10.
To add the python path for anaconda if you are on windows:
Right click my computer
Go to advanced settings
Click on environment variables
Find the PATH variable and click edit
Add the path where your python.exe file is located
Example:
C:\Anaconda3 - might not work
C:\Anaconda3 - then this should work
Same thing for those, who have other installations.
Like #lsxliron mentioned in his comment you should probably check your .bash_profile and make sure that anaconda isn't in your PATH. It should have added itself there during the installation.
You might also want to confirm that IDLE isn't still pointing to the anaconda python that you've now removed.
Also check this question for more details on uninstalling anaconda on OS X.
I have been trying to use Eclipse 3.6 as a Python editor.
I install the latest version of PyDev, and then try to set the Interpreter - Python field of the preferences, on my mac.
My python version is 2.6 and the path is "/usr/bin/python". When I enter this, and I select the items to add to the system PYTHONPATH I get the following error message:
Error: Python stdlib not found
It seems that the Python /Lib folder (which contains the standard
library) was not found /selected during the instal process.
This folder (which contains files such as threading.py and
traceback.py) is required for PyDev to function properly (and it must
contain the actual source files, not only .pyc files) ...
So I can't tell eclipse the interpreter path!
Any help would be great!
(I tried reinstalling PyDev already, no luck)
Thanks!
Following Praveen's answer, My python library is in /library/python/2.6/site-packages. When I enter /usr/bin/python into the interpreter field, eclipse asks me which paths I would like to add to my System PYTHONPATH. One of the checkbox items is exactly that path. So I check it, along with the other boxes. Click ok, and I get the same error.
Had the same problem. Eclipse wouldn't find all the required path using the default installed python (2.6). I downloaded python 2.7, went through the install. My new "which python" path became:
/Library/Frameworks/Python.framework/Versions/2.7/bin/python.
When I tried to set up the interpreter this time, specified this path and it went right through.
Note:
Browse to /Library/Frameworks/Python.framework/Versions/2.7/bin directory
Select the python interpreter that's installed. Sometimes the 'python' link doesn't exist to the current interpreter (say, python3)
just found an answer to my own question, thought it might enlighten other users with similar problems. I will try it out later to see if it works.

When I upgraded to Mountain Lion (10.8.2) I had this problem. The solution was to install XCode 4.5.2, then in XCode > Preferences > Components, there is an option to install the Command Line Tools. I installed them and then I was able install Interpreter.
PyDev needs the location of the python lib folder to get this directory location on your computer try running this command in the terminal.
python -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())"
And add that directory to your PYTHONPATH location in PyDev in Eclipse.
For OS X 10.8 (Mountain Lion) I found a solution here: pydev debugger: unable to find real location for python 2.7 after OS 10.8 upgrade
Seems that there are no command line tools installed by default, so you have to go download them...
I too had the error: stdlib sources not found.
My fix was to install XCode 4.2 and then retry Eclipse's PyDev "Auto Config" method.
No error. PyDev running OK!
I found the solution of not touching macs deliverd python version, but downloading ad installing a new one (currently 3.something)
when setting up the interpreter, point to /usr/local/bin/pyhton3
(to find out the exact path open terminal and type: sudo -s !hittenter> your password !hittenter> cd /usr/local/bin !hittenter> ls !hittenter>)
-> what this does is, showing you the content of the folder you went to. you should find the python interpreter in there.
WARNING!!!!
Do not touch or change any other python files/folders delivered with your mac.
After installing Apple's OSX Developer tools from http://developer.apple.com/xcode/, the necessary .py files will be installed in /library/python/2.6/site-packages. No need to fuss with installing python yourself of using versions of Python not blessed by Apple.
#labjunky , if the .py files from the lib folder in the source tar ball are dropped into the User's site-packages folder ~/Library/Python/2.7/lib/python/site-packages[ provided it is listed in the locations by PyDev and selected] , it works too. this can be useful if the user does not have permission to modify the location in /System/Library/Frameworks/....
In Preferences > PyDev > Interpreter - Python
Choose New...
Name it "Python2.7"
set the path to /usr/bin/python
it then auto-configs some paths, select them, and it proceeds.
I had this issue setting up Jython and solved it as described here: https://stackoverflow.com/a/20002281/1915920
I decided to leave my MAC OS Python 2.7 as is, and instead just install Python 3.3.4.
It works smoothly! :)
1) download python 3.3.4:
The python-3.3.4-macosx10.6.dmg is from http://python.org/download/releases/3.3.4/:
downloaded "from Mac OS X 64-bit/32-bit Installer (3.3.4) for Mac OS X 10.6 and later" (My Mac OS is Mountain Lion).
2) setup Python Interpreter and Lib:
Go to Eclipse Preferences > Interpreter > Python Interpreter and click "Quick Auto Config". It is able to locate the Python 3.3.4, find the interpreter as /usr/local/bin/python3 (which is actually: shulow$ ls -l /usr/local/bin/python3
lrwxr-xr-x 1 root wheel 69 4 Mar 23:18 /usr/local/bin/python3 -> ../../../Library/Frameworks/Python.framework/Versions/3.3/bin/python3)
And it also automatically find the respective libraries in /Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3 which has the .py files (rather than only the .pyc and .pyo)
I got this error because I downloaded the embedded zip file version of Python and extracted it to a folder. I then downloaded the actual installer and ran it. That gave me the stuff that I was missing.
How do I direct Eclipse to the Python interpreter on my Mac?
I've looked in Library which contains the directory 'Python' then '2.3' and '2.5', however they contain nothing except 'Site-packages' - Which is weird considering I can go into the terminal and type python. I then installed the latest 2.6 version with package manager and still can't find it. Can anyone help?
An alias to the python interpreter was likely installed into /usr/local/bin. So, to invoke python2.6, type /usr/local/bin/python2.6 or, most likely, just python2.6. If you want python to invoke python2.6, try rearranging your $PATH so that /usr/local/bin precedes /usr/bin.
Running $which python should help locate your Python installation.
I just solved this for my Mac and it was located in
/usr/bin/python2.7
The way I found it is as follows:
(1) I tried entering the following to see if I could find where Python was located
echo $PYTHONPATH
This had the location of a custom install of Python that came from another program I downloaded, but I wanted the native Python.
(2) I wanted to see every folder in the path so I could look for python
echo $PATH
This returned the following:
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/sbin
(2b) I CDed into every one of these locations and searched for python in each one.
cd /usr/bin/
ls | grep "python"
And I eventually found Python.
In Eclipse, with PyDev, if you (1) click Preferences (2) PyDev (3) Interpreter - Python, you can add the interpreter.
If you have installed python on mac, follow belows steps (on eclipse neon)
Click on Preferences
Search for python
Below screen will appear
Click Choose from list
It will show up all the python installed and select one for you
Hope it helps some one. It resolve my problem.
