When adding the pandas from "poetry init", version 1.3.0 is defined in pyproject.toml, but

Workaround :

• Forcing version of pandas to 1.3.0rc1 works
  poetry add pandas@1.3.0rc1

Hello @al1p,

at the time you've opened this ticket, there were neither a wheel for your target platform nor a sdist file, but other platforms were available. This is why poetry takes this version as the latest available into account.

In the meantime it looks like there are more wheels and also a sdist file available and your issue should be solved.

Can you please try again?
