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$ django-admin startproject diagnosis-admin

(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 ?
