I'm following a book on Django and it has this -> https://hellowebapp.com/setup/ accompanying website. Take a look below at what I'm getting when I get to the "Start your Django project" section of the link.

Here's a peak at my terminal input and feedback.

Note that I already have python 2.7 & 3.5 installed on my system and when referring to python my system is by default pointing to python 2.7. Any ideas?

Try which pip and which python. Both should be in your virtual env's bin directory. django-admin.py should be in the same directory. You can also use locate django-admin.py to find all the files with that name in your file system.

I'm not completely sure how a venv works but I'm guessing the which python & which pip shouldn't be returning an absolute path from root the way they are below. I'm assuming that they should be displaying relative paths from the either the project directory or the venv directory but I don't know for sure

   user@mothership myhellowebapp $ source venv/bin/activate
    (venv) user@mothership myhellowebapp $ which python
    /usr/bin/python
    (venv) user@mothership myhellowebapp $ which pip
    /usr/bin/pip
    (venv) user@mothership myhellowebapp $ locate django-admin.py
    /home/user/.local/bin/django-admin.py
    /home/user/.local/bin/django-admin.pyc

I don't think I bothered to try and install python or pip to the virtual environment but thought I would just use my system wide python and pip for that and instead focust on just installing django localy to the venv. But even when I tried to install python and pip localy to the venv to see if that was the problem this is what I got.

This is strange, there should be a python interpreter in the virtualenv's bin/ directory. Didn't you create the virtualenv with a python interpreter such as in

virtualenv --python=python2.7 mydir

?

[lewashby]

No, I just followed the instructions here -> https://hellowebapp.com/setup/
That site is paired with the Django book I'm reading. Should I have done it differently?

[Gribouillis]

You should be using the python interpreter and the pip command from your venv bin/ directory. What's in your venv's bin directory ?

I just followed the exact same steps from the website again only in a new directory and now everything is working fine. Go figure. Thanks Grib.
