Advice for installing python app from github ?

[Adi44]

Good Evening,

I am just starting out with python (3.11) and i wanted to download an app from github ( a python photo album ). The author has kindly made some instructions, but i am totally lost already !!
in the windows (10) command line i tyype "py" and python 3.11.1 starts with the black screen, then i tried the instructions:-

1.Create venv virtual environment:
virtualenv virtualenv_name

i typed this into the python command line and received :-
>>> virtualenv virtualenv_name
File "<stdin>", line 1
virtualenv virtualenv_name
^^^^^^^^^^^^^^^
SyntaxError: invalid syntax

2. Activate venv virtual environment:
On Linux - source virtualenv_name/bin/activate
On Windows - virtualenv_name/Scripts/activate

does this windows command go into the command line as well ?

3.Firstly you need to clone or download my project from github repositories:
git clone https://github.com/hossainchisty/Photo-Album-App.git

i got this to work, it has been saved into "C:\Users\Adrian\Documents\GitHub\Photo-Album-App"

4. Then enter the corresponding directory:
cd Photo-Album-App

i substituted this for the path that the album has been installed in and received :-

C:\Users\Adrian\Documents\GitHub\Photo-Album-Appcd
^
SyntaxError: unexpected character after line continuation character

i am not sure where any of the following should be typed :-

Install all the requirements using pip:
pip install -r requirements.txt

Run server:
python manage.py runserver

Then go to http://127.0.0.1:8000 in your browser
Create Admin
python manage.py createsuperuser

Access the admin dashboard http://127.0.0.1:8000/admin

the github page is https://github.com/hossainchisty/Photo-Album-App#readme

any advice would be much appreciated !!!

Best Regards

Adrian

You don't create a virtual environment inside python, you create the environment from a shell (windows CMD or powershell).

Once you create the virtual environment you should have no difficulty activating the environment.

These should also be typed in a shell (windows CMD or powershell).

virtualenv_name/Scripts/activate
pip install -r requirements.txt

You are making some error here.

the windows (10) command line i tyype "py" and python 3.11.1 starts with the black screen, then i tried the instructions:-

Don't start Python interactive interpreter,shall use command from command cmd.
Also no need to use virtualenv,as Python now has build in with venv.
You need Git installed to clone the Repo

Quick run demo,i use cmder but commands is the same for cmd.
So it work when i open in browser see album images.

# Make environment

λ python -m venv photo_env

# Cd in

Many Thanks for the replies

I am still confused about ow to create a virtual environment, i open the CMD window as suggested, and do not type "py" ?

i tried, just opening the window and typing "virtualenv virtualenv_name", that just generated an error, also as snippsat said i tried "cmd virtualenv virtualenv_name", then again generated an error.

Am i using the correct syntax ?, as snippsat said just use "venv" ?

when i use powershell and type "virtualenv virtualenv_name", the following occurs :-

PS C:\Users\Adrian> virtualenv virtualenv_name
virtualenv : The term 'virtualenv' 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.

Sounds like Python is not in you PATH. When you installed Python did you ask it to update environment variables?

I dont recall, is it worth doing a clean re-install and if so how do i update the environment variables ?

Thanks for all your help

Just use py to generate the environment.

py -m venv photo_env

Then the rest will be the same.

If Path is correct python and py will work the same.
Test with:

G:\div_code
λ python -V
Python 3.11.3

G:\div_code
λ py -V
Python 3.11.3

G:\div_code
λ pip -V
pip 23.1.2 from C:\python311\Lib\site-packages\pip (python 3.11)

py will always work as it dos not use OS environment path.

Virtualenv is 3-party libayr that need to install .
But is no not needed.

Since Python 3.3, a subset of it has been integrated into the standard library under the venv module.
