I tried to install Python to Windows 10, with the PATH installation included. However, when I click to enter in the Python application, it just appears the setup. I need to access the Python terminal.
Here is the setup
Make sure you are not accidentally opening the Python installation executable. Check again that the Python path is installed properly and try running the command "py" or "python" in the Command Prompt to see if it starts. If it doesn't start and Python is installed on your computer, manually add Python's install location to your PATH.

I have python 3.9 I used the command 'pip install auto-py-to-exe' and it downloaded but when I tried to using the command 'auto-py-to-exe' the program just said " 'auto-py-to-exe' is not recognized as an internal or external command, operable program or batch file.". I have the latest version of PIP and I also have PATH. What can I do to fix this?
This works on VSCode:
python -m auto_py_to_exe
If I install "auto-py-to-exe" using following command, as described in this link as well as from the comment from Justin Ezequiel (above):
python -m pip install auto-py-to-exe
I am able to run it (in Windows 10) using following command:
python -m auto_py_to_exe
This gave me quite a bit of trouble, as none of the above solutions worked for me. Spent lots of time trying to figure out what I should be adding to PATH with no success.
My issue stemmed from (I think) the fact that I have been using python downloaded from the windows store, which uses a different location to store python in.
With the manual install of python (https://www.python.org) you can specify where python is downloaded and automatically add that location to path.
Steps I took to solve the problem:
Uninstall all versions of python downloaded from the windows store via settings (settings > apps > python > uninstall)
Uninstall all version of python via the control panel (control panel > add or remove programs > python x.x.x > uninstall)
Uninstall auto-py-to-exe (pip uninstall auto-py-to-exe) in case it didnt do that automatically
Install python from python.org. (auto-py-to-exe is not supported in versions greater than 3.10 as of 1/23/2023). So I installed Python 3.10
The settings which were successful for me were:
Custom installation,
check install python for all users,
check add to path,
input 'C:\Python310' (with the respective version number) for install location,
install
Check new python version has been installed python --version
Check pip is installed pip --version
Install auto-py-to-exe pip install auto-py-to-exe
When auto-py-to-exe finishes installing, scroll up through the install info and make sure there are no warnings that state there is a location not found in PATH. If there are, you'll have to do some other research on adding those locations to PATH appropriately (since I don't think I was doing that right).
Assuming no PATH warnings,
9. Run auto-py-to-exe
First you need to type in the terminal (not Python):
auto-py-to-exe
If you are currently in python use exit() to exit then try the above code.
It Depends on in which environment you have installed
Make sure to replace {User} with your user
In Conda Enviournment go to below location Manually
C:\Users\{User}\anaconda3\Scripts\auto-py-to-exe.exe
In Pip, Environment go to the location below
C:\Users\{User}\AppData\Local\Programs\Python\Python37-32\Scripts\auto-py-to-exe.exe
or you can add this path to your environment variable as well for accessing these from anywhere
First check you installed it
pip install auto-py-to-exe
then restart your vscode and check another time.
If still an error, check it in CMD.
As suggested above use:
pip show --files auto-py-to-exe to find out in what directory pip has
installed the scripts. Double check the directory is in %PATH%
This will show you where the installer has placed the binary files. I then changed to that directory which circumvents any path issue. I tried to run the files and found :
OSError: [WinError 1920] The file cannot be accessed by the system: 'C:\\Users\\aaaa\\AppData\\Local\\Microsoft\\WindowsApps\\PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0\\python.exe'
PS C:\users\aaaa\appdata\local\packages\pythonsoftwarefoundation.python.3.7_qbz5n2kfra8p0\localcache\local-packages\python37\Scripts>
In my case, although I haven't worked out how to fix it yet... It would seem to be trying to refer to an incorrect Python executable, the files in that directory are all 0 length. Unfortunately the "python -m" suggestion didn't work for me, so it's back to the drawing board. Hope that helps you confirm if it's the right solution to chase down.
You need to make sure you have typed cd C:\Users\your_user_name\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\Scripts as a separate command, and then auto-py-to-exe with python 3. Check in file explorer to make sure your path is correct if the cd fails.
I seem to have a "rogue" copy of python.exe on my Windows 11 machine. When I use it to create a virtual environment with the command "python -m venv venv", it produces an environment in which pip always fails. I have uninstalled Python from the add/remove probrams menu but will when I open a command prompt or a power shell and give the command Python, it responds cheerfully with Python 3.10.5 (main) [GCC 12.1..."
I can't use pip in any virtual environment
How can I determine where it is finding Python? How can I override it with a good Python?
In the Windows Powershell you can use the Get-Command command to find where a specific executable is being ran from. In CMD you can use where.
If you want to use a Python runtime that you have recently installed, and you know where it is located, I would just add that location to my PATH towards the top of the list so that when you run python in your terminal, you get that python.
I downloaded the recent version of python(3.8.3) and selected the 'ADD TO PATH' prompt during setup and it was successfully completed(I checked by running the python.exe file in the source folder) but when i type 'python' or 'python --version' to check which version I am running in the command prompt, it doesn't show anything.
Some of the posts online suggested, to add the path manually again in system variables under environment variables, I did that too but it didn't work. I also tried uninstalling and reinstalling it several times but that didn't work too.
I am running Windows 10 Home 64-bit.
Please Help.
Thank you!
Command prompt
On windows the python executable is py.exe, not python.exe (unless you are using a venv, which uses the latter to access). Use py command instead, i.e. py --version.
I am using Python 3.5.2 version on Windows 7 and tried using python3 app.py. I am getting this error message:
'python3' is not recognized as an internal or external command,
operable program or batch file.
Is there any specific cause about why the python3 command is not working?
I also verified that the PATH is added to environment variables.
There is no python3.exe file, that is why it fails.
Try:
py
instead.
py is just a launcher for python.exe. If you have more than one python versions installed on your machine (2.x, 3.x) you can specify what version of python to launch by
py -2 or
py -3
You can also try this:
Go to the path where Python is installed in your system. For me it was something like C:\Users\\Local Settings\Application Data\Programs\Python\Python37
In this folder, you'll find a python executable. Just create a duplicate and rename it to python3. Works every time.
Python3.exe is not defined in windows
Specify the path for required version of python when you need to used it by creating virtual environment for your project
Python 3
virtualenv --python=C:\PATH_TO_PYTHON\python.exe environment
Python2
virtualenv --python=C:\PATH_TO_PYTHON\python.exe environment
then activate the environment using
.\environment\Scripts\activate.ps1
Yes, I think for Windows users you need to change all the python3 calls to python to solve your original error. This change will run the Python version set in your current environment. If you need to keep this call as it is (aka python3) because you are working in cross-platform or for any other reason, then a work around is to create a soft link. To create it, go to the folder that contains the Python executable and create the link. For example, this worked in my case in Windows 10 using mklink:
cd C:\Python3
mklink python3.exe python.exe
Use a (soft) symbolic link in Linux:
cd /usr/bin/python3
ln -s python.exe python3.exe
In my case I have a git hook on commit, specified by admin. So it was not very convenient for me to change the script (with python3 calls).
And the simplest workaround was just to copy python.exe to python3.exe.
Now I could launch both python and python3.
If python2 is not installed on your computer, you can try with just python instead of python3
For Python 27
virtualenv -p C:\Python27\python.exe django_concurrent_env
For Pyton36
virtualenv -p C:\Python36\python.exe django_concurrent_env
Enter the command to start up the server in that directory:
py -3.7 -m http.server
I had a related issue after installing windows 11, where python3 in cmd would open the windows store. I was able to sort it out between this post and this other one. In short, I reinstalled python and made sure to add it to PATH. Then, in settings, Apps > Apps & Features > App Execution aliases. Here, all I had to do was make sure that every single python .exe (including idle and pip) were turned off EXCEPT FOR the python3.exe alias. Now it works like a charm.
FWIW:
The root of this issue is not with you or with python. Apparently, Microsoft wanted to make installing python easier for young kiddos getting interested in coding, so they automatically add an executable to PATH. For those of us that already have this executable, it can cause these issues.
Found out instead press the play button the top right and it should work in visual studios:
Do not disable according to first answer
Saying python3 in the command will not work by default.
After figuring out the problem with the modules (Solution): https://youtu.be/paRXeLurjE4
Summary:
To import python modules in case of problem to import modules:
Hover over python in search:
Click open in folder
Hover over and right click
click properties
copy everything in path before \python.exe
close those windows
For cmd (administrator):
cd --path that was copied--
then python -m pip install --upgrade pip
cd Scripts
pip install "Name of Package" such as pip install --module (package) --
Im on win10 and have 3.7, 3.8 and 3.10 installed.
For me "python" launches version 3.10 and does not accept commands (like -3.7), "py" launches newest version but does accept commands, and "python3" does nothing.
Uninstalled 3.10 and "python" now does nothing, and "py" launches 3.8.
I am unable to add a comment, but the mlink option presented in this answer above https://stackoverflow.com/a/55229666/8441472 by #Stanislav preserves cross-platform shebangs at the top of scripts (#!/usr/bin/env python3) and launches the right python.
(Even if you install python from python.org, Windows will direct you to the app marketplace nowadays if you type python3 on the command line. If you type python on the same cli it will launch the python.org version repl. It leads to scripts that generate no output, but more likely silently failed completely. I don't know ho common this is but have experienced it on a couple of different devices)
If you have this at the top of your script to ensure you launch python3 and don't feel like editing everything you own, it is not a bad approach at all... lol.
So I am trying to use the "py" command on Windows to select between using Python 2 and 3, but it does not look like "py" got added to my PATH, and I am unsure whether or not it was even installed in the first place. What can I do to install py, or to check if it was already installed and then add it to my path? Thanks.
To see if you have python installed and added to your path:
To add python to your path you need to go to ThisPc>properties>advanced system settings>environment variables>path.
If you believe you have it installed but don't have it on your path then make a basic python program and try running it in python IDLE. e.g print("Hello World") save it as a .py
Just re-run the installer, use the modify/repair option, and select to install the py launcher.
