Re: Creating a new Django project, Stuck with the very first steps

to create your first django project first 

install python on your sysytem

after that you check if you have pip on your sysytem of course it will be there

to check use ths command: pip --version

after that install a virtual environment in case you don't know what virtual environment is it help you make a specific setting to just one project it won't have impact on other project

th commanad is:

pip install virtualenvwrapper

after that let now make the environment

use this command

mkvirtualenv (the name you want to give to your virtual environment)

your environment is automatically generated

install django

use this command: pip install django

before creating your project store in a folder

use this command: mkdir (the name of the folder)

then use this command to open the folder

cd (the name)

after that let create our django project with this command :

use this command: django-admin startprojects (the name of the project)
django will automatically create a folder inside the folder you create then go to the folder with this command

cd (the name of your django projects)

after that

enter this command: python manage.py runserver

Hello, I am wanting to create a django project.

I followed the instructions on installing django here:https://docs.djangoproject.com/en/3.0/intro/install/ and here: https://docs.djangoproject.com/en/3.0/intro/tutorial01/

But I have encountered multiple problems and am stuck.

My env:

Ubuntu on WSL
python 2.7
python 3.5.2

Here is the steps I took so far:

# create the venv
sudo apt-get install python3-venv
python3 -m venv pythonenv
source ./pythonenv/bin/activate


python -m pip install Django
# until there it works


# now, I can't run django-admin startproject diagnosis-admin, fails everytime with a new errors


# pbs with secrets <- pyopenssl <- wheel <- libs
sudo apt-get install build-essential libssl-dev libffi-dev python3-dev  
pip install wheel
pip install pyopenssl


sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev
pip install secrets


django-admin startproject diagnosis-admin

it still fails with an error I don't know what to do with:

(pythonenv) rodolphe@PHP140:~/dev/assistance-tool/diagnosis-admin$ python --version
Python 3.5.2

I didn't expect so many steps and missing/wrong dependencies, so I guess there must be something wrong in the env, or django/python version, but not sure where to look.

Can anyone help ?
