Instalando o pacote Python com o pip - “Tornado requer um módulo SSL atualizado”.

Question

Estou tentando instalar o pacote Tornado Python com pip, mas recebo esse erro. Eu tentei atualizar o Python de 2.7.7 para 2.7.14, mas ainda recebo o erro. Eu tentei pip install --upgrade pip também.

O pip está usando a versão errada do Python?

lx@LX ~ $ python -V
Python 2.7.14
lx@LX ~ $ pip -V
pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7)
lx@LX ~ $ pip install tornado

Corrigido pela instalação do pip novamente
