There’s some discussion on this a while ago on GitHub:
https://github.com/pypa/pip/issues/8450

The problem is likely caused by a corrupt pip installation, and can be resolved by re-initialising pip with the built-in ensurepip module. Once pip is recovered, the suggested upgrade command should work as expected.

The comment with a green tick in the thread lists more detailed commands.

Hello,

When I tried to install a package using pip, it informed me that there is a new version available.
Per the recommendation, I tried to update pip, but the update failed.

The following is the last few lines of the failure messages:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
 File "C:\Users\user\AppData\Roaming\Python\Python38\site-packages\pip\_vendor\distlib\scripts.py", line 386, in _get_launcher

   raise ValueError(msg)

ValueError: Unable to find resource t64.exe in package pip._vendor.distlib

WARNING: You are using pip version 20.2.2; however, version 20.2.3 is available.

You should consider upgrading via the 'C:\Program Files\Python38\python.exe -m pip install --upgrade pip' command.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I can of course supply the full error traceback, if needed, not just these last few lines.

The file:
c:\Users\user\AppData\Roaming\Python\Python38\site-packages\pip\_vendor\distlib\t64.exe
DOES exist.

I just installed the latest python version 3.8.6 – I would have thought it would already include the latest version of pip…

Any help resolving this failure will be much appreciated.
