Marcos,

O próprio PIP já esta falando o possível problema, vc esta usando um versão muito antiga do mesmo!

"You are using pip version 10.0.1, however version 18.0 is available."

Atualiza o seu pip, como demostrado por ele:

pip install --upgrade pip

depois o flask_mysql vai instalar normalmente:

pip install flask_mysql

que coisa não?! xD

mas agora veja o que aconteceu.

Marcos,

Só por curiosidade, no seu terminal, digita?

python --version

eu uso a versão 2.7.12

Marcos,

Vc tem que usar o pip da versão 2.7.12, digita no terminal que vai funcionar? Desculpe eu deveria ter comentado isso antes!

Atualiza o seu pip, como demostrado por ele:

pip2.7 install --upgrade pip

depois o flask_mysql vai instalar normalmente:

pip2.7 install flask_mysql

eu que peço desculpa pela insistência. Mas...:

Consegui arrumar cara! Esse foi o comando que usei

 sudo pip2.7 install flask_mysqldb

e fiz o import do :

flast_mysqldb
