How install fontTools in python

Question

I wrote a program in python 3.6.2(32 bit) in Windows, and imported the following libraries.

from tkinter import font
from fontTools.ttLib import TTFont
from tkinter import messagebox
import tkinter.font as font
from tkinter.ttk import Separator, Style
from tkinter.filedialog import *
import tkinter as tkfont 

When I run the code, I get this error:

No module named 'fontTools'

When I install the module via this command:

pip install fontTools

I get the following error:

Could not find a version that satisfies the requirement fontTools (from versions: )
No matching distribution found for fontTools

How can I fix this?

Answer 1

As the documentation states:

pip install fonttools

It's all lowercase.
