ERROR: Could not build wheels for pandas, which is required to install pyproject.toml-based projects

Question

I'm trying to install pandas via pip install pandas on my laptop.

Environment:

• Window 11 Pro
• Python 3.10.4
• Pip version 22.0.4

Compatibility:

• Officially Python 3.8, 3.9 and 3.10.
• You must have pip>=19.3 to install from PyPI.

C:\Users\PC>pip install pandas

  note: This error originates from a subprocess, and is likely not a problem with pip.

What I have tried:

• updated pip to 22.1.1
• installed wheel 0.37.1
• uninstalled and installed pip
• uninstalled and installed python 3.10.4

Error still reproducible with pandas 1.5.1

Thanks to @AKX which has pointed up that there is no and may will no 32-bit version of pandas in the future. See the discussion on GitHub.

try pip install manager then *pip install pandas* - where I found this – Dagoba

@PrestigeDev thanks for your advise, but I ran into a different error to install this package error: metadata-generation-failed. Im trying to install scipy now. If I have similar issues I'll try to reinstall python. – Kuhlman

I would use Anaconda if that doesn't work – Dagoba

"The easiest way to install pandas is to install it as part of the Anaconda distribution, a cross platform distribution for data analysis and scientific computing." - pandas - Installation – Dagoba

@PrestigeDev I do not like the idea of being forced to use anaconda for pandas. If there was not a regular way with PyPi I would agree and its a normal condition, but since it does not explicitly state it is necessary I would like to have it work. :D But thank you for your time and effort to solve my issue. – Kuhlman

Answer 1

Pandas doesn't require Anaconda to work, but based on python310-32 in your output, you're using a 32-bit build of Python.

Pandas evidently does not ship 32-bit wheels for Python 3.10 (they do have win32 wheels for Python 3.8 and Python 3.9 though). (There could be alternate sources for pre-built 32-bit wheels, such as Gohlke's site.)

In other words, on that platform you would need to install Pandas from source, which will likely be a rather difficult undertaking, and can't be done directly within pip anyway (as you noticed via error: metadata-generation-failed).

If your system is capable of running 64-bit Python, you should switch to it.

First of all, thanks for clearing this up. Could you please elaborate why I shouldn't wait for a 32-bit wheel, rather than switching to 64-bit python? As far as I know it is just important for extensive memory usage. – Kuhlman

I don't think there will be a 32-bit wheel (it would have been uploaded along with the other wheels), so you'd wait for a long time. – Ingeborgingelbert

They seem to hesitate with it – Kuhlman

:shrug: Well, judging by the timestamps on that issue you'll still be waiting for a long time for them to finish hesitating. – Ingeborgingelbert

lmao, yes. I'm not in hurry. Though, I will need it in the future again. – Kuhlman

It would be easier to just go with 64-bit Python. Is there a reason for you to stick with 32-bit? – Ingeborgingelbert

No particular, no. But I remember some other technologies I have used in the past wasn't available in 64-bit. That's why I had switched from 64-bit to 32-bit in the first place. I rather thought about starting to use virtual environments so I will be more flexible in the future and maintain both for my projects. – Kuhlman

You should always use virtualenvs-per-project anyway. I would still recommend switching over to 64-bit – if there are things that don't work in 64-bit, shame on them... – Ingeborgingelbert

I have 64-bit Python and am facing the same problem as OP. – Ekaterinburg

Answer 2

Install pandas in Python 3.10

python -m pip install pandas

Bughouse

Answer 3

Step one

Download pandas wheel, Choose one that suits your operating system

Step two

install the wheel from absolute path

pip install pandas-1.4.2-cp310-cp310-win32.whl

Step three

You had successful installed pandas Check it

import pandas

Answer 4

the problem i had was error on microsoft visiual, mention befor the error of wheel of panda, needed the package of that before install pandas with pip install. now after install the microsoft visiual then use pip install panda and then pip install transform i had no errors.

Please update your answer to make the issue and solution clearer, and also correct the spelling and grammar. As it is currently written, it is hard to understand. Thanks. – Linc

Answer 5

I solved the problem by lowering the python version from 3.10 to 3.9. Maybe you can have a try!

That answer is included in the accepted answer. – Kuhlman
