ERREUR: Impossible de construire des roues pour PYMSSQL qui utilisent Pep 517 et ne peut pas être installé directement

J'essaie d'installer Pymssql de PIP sous Windows. Le problème est que je continue à obtenir l'erreur suivante:

ERROR: Failed building wheel for pymssql
Failed to build pymssql
ERROR: Could not build wheels for pymssql which use PEP 517 and cannot be installed directly

Le journal complet est comme suit:

Quelqu'un a-t-il eu ce problème? J'ai cherché loin de loin, mais pas de réponses. J'ai essayé de descendre PIP et j'ai également essayé d'installer des versions plus anciennes de PYMSSQL, mais pas de chance.

Je rencontre la même erreur, une solution différente.

I.M UTILISANT MAC + PY3.9

solution:

brew install freetds

      You can install FreeTDS with Homebrew or MacPorts, or by downloading
      and compiling it yourself.
