I can't figure out how to install pytz. In the video it says to use 'pip install pytz', but where am I supposed to type this? I've tried the Python shell, the Python command line, and Powershell. I have Python 3.4.

Second, try python -m pip install pytz from Powershell or a regular command prompt.

4,268 PointsThank you so much for your answer! I had Python in PATH but not the Script subdirectory. After changing that I was successfully able to use the 'python -m pip install pytz' command in Powershell.

pip install pytz. If you're using a Mac, I hope this helps.

7,833 PointsI'm having trouble installing this module as well. Unfortunately, I don't understand the answer given. Can someone give step by step instructions on how to do this? I'm using Python 3.5 on Windows. All I know how to do is use the shell (IDLE) and write scripts by clicking File New File from the shell.

Treehouse Moderator 32,252 PointsSo there's a sneaky way to install modules from IDLE. Run these commands (one line at a time in IDLE):
from subprocess import call
call("pip install pytz", shell=True)
Then you can carry on with importing the module:
import pytz
Note that you need to import the module each time you use it, but only have to install it once.
