Unica coisa que encontrei sobre o erro do cpp 14 required foi em relação ao setuptools, e esses dois comandos, para instalar o setuptools, caso informe que já ta instalado, tentar forçar a atualização com o segundo comando. Lembre de usar o pip e python certo, se no seu sistema ta python3 e pip3 troque ai.

pip install setuptools
python -m pip install -U pip setuptools
