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.

11,012 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 32,305 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.

Treehouse Moderator 68,441 Pointspip installshould be run at in a bash or powershell window. A virtualenv may used within the shell to localize the install to that end. What error are you seeing when trying in powershell?
