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


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:

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.


Solution

  • 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.
