Using PIP in Python 3.10 on Windows 10

[Jonathan Gossage]

I have installed Python 3.10.1 on Windows 10 using the recommended Windows
Installer. When I try to access PIP from the command line, I get the
following result, even though Python itself is accessible.


C:\Users\jgoss>python
Python 3.10.1 (tags/v3.10.1:2cd268a, Dec  6 2021, 19:10:37) [MSC v.1929 64
bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> quit()

C:\Users\jgoss>pip install pip --upgrade
Fatal error in launcher: Unable to create process using '"C:\Program
Files\Python310\python.exe"  "C:\Program Files\Python310\Scripts\pip.exe"
install pip --upgrade': The system cannot find the file specified.
During the installation, I chose to install Python in a non-default
location and to set the Environment variables.
 The result of this attempt is shown below:


C:\Users\jgoss>python
Python 3.10.1 (tags/v3.10.1:2cd268a, Dec  6 2021, 19:10:37) [MSC v.1929 64
bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> quit()

C:\Users\jgoss>pip install pip --upgrade
Fatal error in launcher: Unable to create process using '"C:\Program
Files\Python310\python.exe"  "C:\Program Files\Python310\Scripts\pip.exe"
install pip --upgrade': The system cannot find the file specified.

It looks as if the launcher is expecting to find Python installed at
c:\Program Files\Python3.10 whereas it has actually been installed at
D:\Users\jgoss\AppData\local\python\python3.10. It seems that the launcher
has not been updated to the latest installation location for python and
that it also needs to handle a non-default install location. The same
problem occurs if I take the install option to install to the default
location.
Is there any workaround as PIP is essential to my environment?
