Document Windows 10 update solution

[rowebyrowe]

Environment

• pip version: 20.0.1
• Python version: 3.7.6
• OS: Windows 10

Description

I am trying to upgrade pip and while rolling back the uninstall of pip, it runs into an exception telling me that it can't find t64.exe in pip._vendor.distlib. I'm presuming that it means "C:\Users\jeffr\AppData\Roaming\Python\Python37\site-packages\pip_vendor\distlib". I checked that folder and found t64.exe there.
Expected behavior

Pip should upgrade without any errors and should be able to notice t64.exe.
How to Reproduce

1.Open command prompt in admin mode
2. type 'python -m pip install --upgrade pip'

Output

C:\WINDOWS\system32>python -m pip install --upgrade pip

I believe you might have a typo in the distlib path you shared in the issue (pip\_vendor instead of pip_vendor).

Also may I ask if the suggested command in the error message of upgrading through Anaconda via 'C:\ProgramData\Anaconda3\python.exe -m pip install --upgrade pip' works?

I believe there was an upgrade to the vendored distlib in #7618 where this particular error was addressed and changed to ValueError (https://bitbucket.org/pypa/distlib/commits/305a20488486d3c0f3cba4c6810442140ed2848e)

Try upgrading pip.

[vikash-jain]

Saw somewhere else on the web and tried following steps individually on the command prompt. It helped me move ahead. You can give it a try.

python -m pip uninstall pip
python -m ensurepip
python -m pip install -U pip

python -m pip uninstall pip
python -m ensurepip
python -m pip install -U pip

I also got it solved using this one.
Thanks a lot @vikash-jain

[uranusjr]

I’ll attribute this to a botched pip upgrade. Whatever the cause is seems to have not occured again. It would be nice if someone can submit a pull request to the documentation for future reference.

The easiest way to upgrade pip: easy_install pip
It gives no errors, and it works.
