Could you help me?

It's my first installation; i followed official howto

[Ed McDonagh]

Hi Leonardo

What was the URL you were using? (http://...)

Which web server are you using - built-in runserver or IIS?

Are you making use of a virtual_directory for your webserver?

Kind regards

Ed

I've the same error on windows 10 (linke in https://www.youtube.com/watch?v=MYhVXVzRsB8)  and ubuntu. I'm probably doing the same error

[Ed McDonagh]

Have you followed the YouTube instructions then, rather than the instructions at  https://docs.openrem.org/ ?

Those instructions were put together by Daniel Carrion at The Imaging Physicist, independent of the OpenREM team. They are great, but they were done 2.5 years ago for a version that has been superceded a few times since then.

I wonder if you might be able to start again with the official documentation? I don't have the resources just now to check the differences to see where the problem lies; I don't know if anyone else might know? 

Right now I am working on packaging the next version in Docker, so once you have Docker installed the OpenREM install process will be very easy. But for now, for version 0.10 the best bet is to try and follow the official documentation at docs.openrem.org.

Kind regards

Ed

Hi Ed,

I'm installing Openrem 0.10.0 on a pc with ubuntu 18.04. I'm following the online instructions plus the pdf docs. I have the same problem as Leonardo. I tried the istallation two times, but when I test the services (python mane.py runserver --insecure)

 -I'm trying to connect to  http://localhost:8000

- I'm using the internal server (runserver). If I'm right this should be the first step to check, from which to move to NGINX and Gunicorn

- I'm not using a virtual directory for the web server.

Hi Margherita 

Are you using the https://docs.openrem.org docs?

There is a mix of /var/dose/ and /var/dose2/ paths in your traceback there - why is this?

Kind regards

Ed

Hi Ed, yes I'm using the docs at that link. 

The reason why there were both /var/dose/ and /var/dose2/ is that I tried the installation twice using first dose and then dose2 folders. Now I deleted the /var/dose/ folder, but the errors are exactly the same (except that now there is only the /var/dose2/ path indicated, as it should be)..

From the terminal:

(veopenrem) openrem@openrem-Celsius-W420:/var/dose2/veopenrem/lib/python2.7/site-packages/openrem$ python manage.py runserver --insecure

Performing system checks...

System check identified no issues (0 silenced).

I checked online for some help, but I could not find where the error could possibly be.. the istallation went fine without any error.

[Ed McDonagh]

Hello again. I think the problem is one of the libraries has been updated and doesn't support Python 2.7 anymore. 

Can you please try the following install in your virtenv?

pip install django-crispy-forms==1.8.1

and let me know how you get on.

Hi Ed, yes it worked! 

I've installed v.1.8.1 (automatically unistalling v. 1.9.0)  and now I have access to the Openrem page.

Thank you very very much, 

Margherita

[Ed McDonagh]

Thanks for feeding back. I'll update the docs - this is going to be more and more of an issue until version 1 with Python 3 support is released! See https://bitbucket.org/openrem/openrem/issues/825/django-crispy-forms-190-is-python-3-only

Leonardo - this is presumably the issue you hit as well. You might like to try the same fix too.

Kind regards

Ed

Hi Ed,

Thanks for this, it worked and fixed a fresh install on Win 10 too.

Looking forward to v1 Python 3!

Kind regards
