Problem running auto py to exe from terminal [duplicate]

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 do not know why I get the notification that pip is not on my computer [duplicate]

I'm running into a weird error when trying to install Django on my computer.
This is the sequence that I typed into my command line:
C:\Python34> python get-pip.py
Requirement already up-to-date: pip in c:\python34\lib\site-packages
Cleaning up...
C:\Python34> pip install Django
'pip' is not recognized as an internal or external command,
operable program or batch file.
C:\Python34> lib\site-packages\pip install Django

What could be causing this?
This is what I get when I type in echo %PATH%:

You need to add the path of your pip installation to your PATH system variable. By default, pip is installed to C:\Python34\Scripts\pip (pip now comes bundled with new versions of python), so the path "C:\Python34\Scripts" needs to be added to your PATH variable.
To check if it is already in your PATH variable, type echo %PATH% at the CMD prompt
To add the path of your pip installation to your PATH variable, you can use the Control Panel or the setx command. For example:
setx PATH "%PATH%;C:\Python34\Scripts"
Note:
According to the official documentation, "[v]ariables set with setx variables are available in future command windows only, not in the current command window". In particular, you will need to start a new cmd.exe instance after entering the above command in order to utilize the new environment variable.
Thanks to Scott Bartell for pointing this out.

For Windows, when you install a package, you type:
python -m pip install [packagename]

As of now, version 3.7.3 I had a little bit of an issue with getting the right system variable.
Try this:
Type start %appdata% in cmd.
After that file explorer should pop up in ../AppData/Roaming.
Go back one directory and navigate to Local/Programs/Python/Python37-32/Scripts.
NOTE: The version number may be different so if you copy and paste the above file path it could not work.
After you do this you now have the correct location of your downloaded Python. Copy your file path by selecting the whole directory in the address bar.
Once you do that click the start icon and navigate to the Control Panel → System and Security → System. Then click "Advanced System Settings" on the left side of the panel.
Once there, click Environment Variables on the bottom right and there will be two boxes, an upper and a lower box. In the upper box: Click on the 'Path' Variable and click Edit located on the right. Click New and paste your directory Path. It should look something like this:
Click OK three times, open a new window of cmd and type: pip. See if it works.

For me the command:
set PATH=%PATH%;C:\Python34\Scripts
worked immediately (try after echo %PATH% and you will see that your path has the value C:\Python34\Scripts).
Thanks to: Adding a directory to the PATH environment variable in Windows

Alternate way.
If you don't want to add the PATH as the previous well written answers pointed out,
but you want to execute pip as your command then you can do that with py -m as prefix.
Given that you have to do it again and again.
eg.
py -m <command>
as in
py -m pip install --upgrade pip setuptools
Also make sure to have pip and py installed

The only way that worked on my Windows 10 machine was as follows:
py -3 -m pip install xxxxx

Also, the long method - it was a last resort after trying all previous answers:
C:\python27\scripts\pip.exe install [package].whl
This after cd in directory where the wheel is located.

As per Python 3.6 Documentation
It is possible that pip does not get installed by default. One
potential fix is:
python -m ensurepip --default-pip

Control Panel -> add/remove programs -> Python -> Modify -> optional Features (you can click everything) then press next -> Check "Add python to environment variables" -> Install
And that should solve your path issues, so jump to command prompt and you can use pip now.

Go to control Panel >> Uninstall or change Program and double click on Python XXX to modify install. Make sure PIP component is checked and install.

I was having the same problem just now.
After adding the proper folder (C:\Python33\Scripts) to the path, I still could not get pip to run. All it took was running
pip.exe install -package- instead of
pip install -package-.

Try going to Windows PowerShell or cmd prompt and typing:
python -m pip install openpyxl

In latest version Python 3.6.2 and above, is available in
C:\Program Files (x86)\Python36-32\Scripts
You can add the path to our environment variable path as below
Make sure you close your command prompt or Git after setting up your path. Also should you open your command prompt in administrator mode. This is example for Windows 10.

Use
set Path = `%PATH%;C:\Python34\;C:\Python27\Scripts`
Source

Or if you are using PyCharm (2017-03-03) like me, just change directory in terminal and install:
cd C:\Users\{user}\PycharmProjects\test\venv\Scripts
pip install ..

Most frequently it is:
in cmd.exe write
python -m pip install --user [name of your module here without brackets]

Even I'm new to this, but pip install django worked for me.
The path should be set as where the script folder of the Python installation is, i.e.C:\Python34\Scripts.
I suppose it's because Django is a framework which is based on Python, and that's why this directory structure has to be maintained while installing.

I have just installed Python 3.6.2.
I got the path as
C:\Users\USERNAME\AppData\Local\Programs\Python\Python36-32\Scripts

In Windows, open cmd and find the location of PYTHON_HOME using where python. Now add this location to your environment variable PATH using:
set PATH=%PATH%;<PYTHON_HOME>\Scripts
Or refer to this.
In Linux, open a terminal and find the location of PYTHON_HOME using which python. Now add the PYTHON_HOME/Scripts to the PATH variable using:
PATH=$PATH:<PYTHON_HOME>\Scripts
export PATH

You can try pip3. Something like:
pip3 install pandas

I was facing the same issue. Run Windows PowerShell as Administrator. It resolved my issue.

None of these actually worked for me, but running
python -m pip install -U pip
and then adding the specified directory to the PATH as suggested got it working

In your Python folder path in Terminal, just type
py -m pip
in order to check the current version of your pip.
You will also see a list of commands, you can use...

I think from Python 2.7.9 and higher pip comes pre installed and it will be in your scripts folder.
So you have to add the "scripts" folder to the path. Mine is installed in C:\Python27\Scripts. Check yours to see what your path is so that you can alter the below accordingly. Then go to PowerShell, paste the below code in PowerShell and hit Enter key. After that, reboot and your issue will be resolved.
[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27\Scripts", "User")

In a Windows environment, just execute the below commands in a DOS shell.
path=%path%;D:\Program Files\python3.6.4\Scripts;
(new path=current path;path of the Python script folder)

I deleted the older version using the control panel and then installed the new version however the newer version was not reflecting pip even after adding the right paths in the environment variables. However, the thing that worked for me was deleting the folders of old python that were there in the local App folder even after uninstall. For me, the path was like below. Deleting this folder solved my issue
C:\Users\username\AppData\Local\Programs\Python38

'pip' is not recognized as an internal or external command
pip is a python module used to install packages. For your problem, there can be many reasons;
Restart CMD/Terminal
Environment variable is not set. pip is installed but environment variable is not set. Environment variable is a windows variable where pip path is saved, so it can be run at run time.
pip is not installed.
Restart CMD/Terminal
It is sometimes possible that you opened your command prompt or terminal before installing pip and now it just needs a restart to pick up the latest environment variables. It is worth trying just restarting your command prompt or terminal.
Environment Variable is Not Set
Open CMD and run this command to see the values set in the PATH environment variable.
echo %PATH%
This will echo the PATH environment variable like this;
You should check if your path exist in the echoed PATH list. For example, in my case, the path for pip.exe files is C:\Python310\Scripts. You can check this path yourself like this;
If you can find pip path and it does not exist the echoed PATH variable, then we need to add it. Copy the path like C:\Python310\Scripts.
Go to Start > This PC > Properties > Advance system settings >
Advanced > Environment Variables
As shown in the image above, Select Path, click Edit button and add the copied path. Restart the CMD and test pip command again.
pip is Not Installed
If pip is not installed, you can install it again by downloading latest python.exe setup from python.org website. Make sure you check mark the pip option as shown in the image below.
In the next step, check mark "Add Python to environment variables"

I had this same issue. You just need to go to your
C:\Python27\Scripts
and add it to environment variables. After path setting just run pip.exe file on C:\Python27\Scripts and then try pip in cmd. But if nothing happens try running all pip applications like pip2.7 and pip2.exe. And pip will work like a charm.

Small clarification: in "Windows 7 64 bit PC", after adding ...Python34\Scripts to the path variable, pip install pygame didn't work for me.
So I checked the "...Python34\Scripts" folder, it didn't have pip, but it had pip3 and pip3.4. So I ran pip3.4 install pygame .... .whl. It worked.
(Further open a command window in the same folder where you have the downloaded pygame...whl file.)

When installing SQL 2019 Python, there are known issues for PIP which require a fix (step 7)
https://learn.microsoft.com/en-us/sql/advanced-analytics/known-issues-for-sql-server-machine-learning-services?view=sql-server-ver15
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Workaround
Copy the following files:
libssl-1_1-x64.dll
libcrypto-1_1-x64.dll
from the folder
C:\Program Files\Microsoft SQL Server\MSSSQL15.MSSQLSERVER\PYTHON_SERVICES\Library\bin
to the folder
C:\Program Files\Microsoft SQL Server\MSSSQL15.MSSQLSERVER\PYTHON_SERVICES\DLLs
Then open a new DOS command shell prompt.

Unable to update PATH variable for pip on Windows 10

I know there are thousands of similar topics but my pip command has suddenly stopped to work and, despite all my researchs, I can't figure out why. It has been a while since I last used pip and surprisingly my computer doesn't recognize the command anymore. I reinstalled pip and the prompt tells me that the PATH variable is not correctly updated. So I update it but that doesn't solve the problem, the prompt still tells me the PATH variable is not updated. I've tried uninstalling and reinstalling python and pip and nothing works.
In my environment variables, I have a user variable named PATH and a system variable named PATH, both of them have the value :
C:\Users\mertz\AppData\Local\Programs\Python\Python38\Scripts\
The user variable was already written by itself and I had to write the system variable myself.
When I'm installing pip I get this warning :
WARNING: The scripts pip.exe, pip3.6.exe and pip3.exe are installed in 'C:\Users\mertz\AppData\Local\Programs\Python\Python36-32\Scripts' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
And when I type pip in the command prompt, it tells me that pip is not recognized.
What did I do wrong ?
Thanks in advance

I had a similar problem, at one time: I could only use administrative privileges to use python cmd or pip easy_install.
PLEASE follow these procedures:
Get to your environmental variables by pressing window + r and type-in, sysdm.cpl and click ok.
Copy the pip link directory to the script folder in python,
but first check for pip, pip3, easy_easy, etc.
If it doesn't contain pip, you have to uninstall python and delete the folder, and then reinstall python.
i.e
C:\Users\mickeymouse\AppData\Local\Programs\Python\Python38-32\Scripts.
You will see user variables and system variables.
(user variables are applied for only that user's account; system variable are applied to all accounts on the pc).
Create a path for both, then restart cmd.

I'm not a specialist in Pip or Python, but I faced a similar problem and used a different procedure.
I believe Pip cached directories depend on user permissions during installation and update.
At first, the Pip installer defaults to the Python home directory for caching files. If such a directory is unreachable, the installer creates a cached directory inside the current user's home directory.
Since Python includes Pip by default, the issue reported should not happen at the first install, yet it is due to trying to run the update without administrative privileges.
If that is the case, you could try the following steps:
Assert the system PATH has proper Python directories assigned, e.g.:
C:\Program Files\Python310\ for Python executable files;
C:\Program Files\Python310\Scripts\ for Python scripts and extensions.
Remove Pip's registered cached directories using the command py -m pip cache purge.
Search for and remove any Pip content outside the Python subdirectory. For example, you could check for contents such as [user home directory]\.pip and [user home directory]\pip.
Remove Pip references from the system and the user PATH variables.
Open Windows Terminal with administrator privileges and rerun the Pip installer command. You should not use the --no-warn-script-location option, or else you will not be able to see if there is any unexpected behavior.
Finally, to my knowledge, Pip's documentation lacks a consistent reference for directory options. Anyway, the following links provided me with some clarity:
Pip general reference:
https://pip.pypa.io/en/stable/
On Pip caching strategies:

All the best!

Cannot install PIP on Windows 10

I ran the Python 3.5.1 installer from https://www.python.org/downloads/release/python-351/. However, on the command line, when I go to run pip, I see an error: 'pip' is not recognized as an internal or external command.
Is there something wrong?

The solution is to get the latest pip installer script from:
https://bootstrap.pypa.io/get-pip.py, and install it with python get-pip.py.
Then you can use commands like python -m pip ... to your heart's content.

You must to add pip's path into Environment Variables. Pip is contained in python's script directory.
Example my case: C:\Python34\Scripts\pip.exe
To add path to environment variables.
Hold Win and press Pause.
Click Advanced System Settings.
Click Environment Variables.
Add C:\Python34\Scripts (Sorry I don't know name of python 3.5's directory) to the Path on System variables.
Restart Command Prompt.
Edit
In another way, you can use pip-Win instead of pip. Read more here: https://sites.google.com/site/pydatalog/python/pip-for-windows
