I don't remember needing to install pip with Windows installations. I've 
got 3.11.3 on Windows 10. The installer and source distro for Windows 
both come with the ensurepip module:


 -m ensurepip

will install pip, where  is the name of the version of Python 
you want to run. I assume (but don't know for sure) that the standard 
installer runs ensurepip as part of its work.


How (and why) did you try to install it?

The error is coming from Lib\site-packages\pip\_internal\cli\parser.py. 
It's possible that some inconsistency has crept in between the allowed 
options and the ones that are given to the parser.

Pip is installed by default with the python.org kits.
I am not sure what the situation is for the app store python.

Can you run python it self?

Does one of these work for you?

py -m pip
python -m pip

If so you have pip installed.

There's a long-running thread on this in, well, more than one place.

The experts on the Windows experience in general (i.e. Microsoft folks)
maintained for a long time that the 32-bit Python was the correct
default - they have usage statistics on a worldwide basis that nobody
else could have access to. That stance may have softened a bit but
there's been no change to the web page yet.   The web page does OS
detection, but not bitness-detection, and yes that's intentional but
won't go into that here.

The 32-bit Python runs just fine on 64-bit Windows, by the way. There
shouldn't have been a problem with it.  There's also nothing wrong with
switching to the 64-bit version if you like - mainly that choice should
these be driven by what extra packages are available; for a long time it
was more likely that binary wheels were available for 32-bit Python, and
I think now that's actually shifting such that some developers may not
be uploading the 32-bit wheels any longer.

I have had the same problem in the past. Most software download pages 
seem to detect whether you are running 32 or 64 bit, and default to the 
correct download option.


Python shows a big yellow 'Download the latest version for Windows' 
button, which most people will select by default. However, it actually 
downloads the 32 bit version, without any indication that this is what 
it is doing.


I could have the details wrong - I am not going to repeat the install 
just to check. But this is what I recall from the last time I did this.


This seems like a good time to bring this up, as in another thread we

Re: "pip" error message

[Simone Bravin]

Hi all,

First of all thanks to all that answered my question.

I had already changed the PATH and tried to upgrade pip version but it 
was not possible to reach pip in any way,

the error that I was getting looked like regarding some program file of pip.

Anyway after some trying I was able to fix the problem.

I found that I had downloaded Python from what I would call "automatic 
check version link" and that downloaded the 32-bit version, but my 
notebook have 64-bit, so I changed the version to the 64-bit one.


Pip was reachable but I was getting a problem with it again anyway was 
an easiest fix as I had to take off the -32 from \Python38-32\ in PATH 
variables, like this: 
C:\Users\simon\AppData\Local\Programs\Python\Python38\Scripts


Bye

Re: "pip" error message

[Richard Guinn]

Hi Simone and all -
I'm not sure how to fix/correct... but just a redundant 'me too'.  I tried
to install pybibframe (https://pypi.org/project/pybibframe/) and also keep
getting errors.  Wasn't sure if it was the module/package or what.

My error is along the lines of:

  ERROR: Command errored out with exit status 1:
 command:
'c:\users\rickrigby\appdata\local\programs\python\python38-32\python.exe'
-u -c 'import sys, setuptools, tokenize; sys.argv[0] =
'"'"'C:\\Users\\RickRigby\\AppData\\Local\\Temp\\pip-install-_x4to3h7\\amara3.xml\\setup.py'"'"';

When I 'Google' the error - I find that there's an apparent bug
https://stackoverflow.com/questions/60937863/error-command-errored-out-with-exit-status-1


Doesn't sound like there's an easy workaround.

Those aren't errors, and pip should be perfectly usable.  The message
about `/home/steve/.cache/pip` is just because pip is being run via
sudo; pip's cache dir is based on $HOME, which is still set to
`/home/steve` and pip doesn't want to screw up its cache for the
`steve` user.  The "Ignoring indexes" message is due to ensurepip
explicitly disabling pulling from PyPI when installing pip and
setuptools.

The messages about the cache do look a bit unnecessarily scary, it
might be nice if they didn't appear when pip is run by ensurepip.  I'm
not sure what removing the message for that particular case might
entail, but it might be worth opening an issue for it.
