eb : The term 'eb' is not recognized as the name of a cmdlet, function, script file, or operable program

I'm trying to deploy my Django Application with AWS beanstalk following this documentation: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html

Everything works up till this point:

~/ebdjango$ eb init -p python-3.6 student-archive

When I run that line of code I get this error:

eb : The term 'eb' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path 
is correct and try again.

+ eb init -p python-3.6 studentarchive
+ ~~
    + CategoryInfo          : ObjectNotFound: (eb:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

What could be some causes of this? Here's my django.config:

option_settings:
  aws:elasticbeanstalk:container:python:
    WSGIPath: StudentArchive/wsgi.py
