Hello, Im facing an issue on the shared host server, Im using

$ pip install -r requirements.txt
You are using pip version 7.1.0, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

This is the error message I get. I hope you can help me

[foxmask]

are you using python 3 ?

[petrk94]

By default on the shared host server is Python -V 2.7 But there is even Python 3. The problem, Pip seems to choose the older Python version. And I don't know how to use pip with Python3

[foxmask]

Use pip3 instead ;)

I have tried, looked good a the beginning, but failed too:

This error occurs because you are connected as an end-user and try to install files into directories where you dont have the rights.

So first of all start by creating a new virtualenv like this:

python -m venv <the name of virtualenv you want>

then go into that virtualenv

cd <the name of virtualenv you want>

activate the virtualenv by:

source bin/activate

then clone

git clone https://github.com/foxmask/dj-diabetes.git

then install

cd dj-diabetes
pip3 install -r requirements.txt

[petrk94]

ok thanks, this worked now all and the migration was successful. But now I have it in /var/www/virtual/xxxx/diabetes/dj-diabetes/

How I can run it as subdomain and which commands are necessary to start the python server for this project?

[tylergale]

I'm assuming you would need some sort of HTTP proxy, such as Nginx? Check https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04

[petrk94]

@tylergale is it even possible without? This all seems to be very complicated, just to set this up and make it reachable, especially I can not just easily install a Nginx Server on my shared host account.

[foxmask]

@petrk94 you can install this project on your desktop for your own usage and thus no need to setup NGINX, just start

python manage.py runserver &

and access to the project by http://127.0.0.1:8000/

If you plan to host it on a (shared hosting) server provider without any knowledge, that will be very complicated.
