Installation Logs

I encountered an error while attempting to install pandas<0.21 using pip on Windows 10. Specifically, the error occurred during the preparation of metadata, with the following message:

Preparing metadata (pyproject.toml) ... error error: subprocess-exited-with-error

error: subprocess-exited-with-error

× Preparing metadata (pyproject.toml) did not run successfully. │ exit code: 1 ╰─> [3 lines of output] error in pandas setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Expected end or semicolon (after version specifier) pytz >= 2011k ~~~~~~~^ [end of output]

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

× Encountered error while generating package metadata.

The error message suggests that there was a problem with the metadata generation process during installation. Specifically, there was an issue with the install_requires command in the setup.py file for pandas. The error message indicates that a valid version specifier was expected after the pytz >= 2011k requirement, but it was missing. This issue caused the metadata generation to fail, and subsequently the installation of the package failed.

Hi, thanks for your report. We don't support these old versions anymore.
