Am implementing a sign up using python & mysql. 
Am getting the error no module named flask.ext.mysql and research implies that i should install flask first. They say it's very simple, you simply type
pip install flask-mysql
but where do i type this? In mysql command line for my database or in the python app?
You should be able to type it in the command line for your operating system (ie. CMD/bash/terminal) as long as you have pip installed and the executable location is in your PATH.
Where do i enter pip install flask-mysql?
