I can't run django server nor activate the virtualenv

[Fred DJar]

Hello guys, i'm a newbie so bear with me :)

I have installed python 2.7 and django 1.6 on my desktop (ubuntu 14)
but i can't run the application or activate the virtualenv

this is the message i got:
ubuntu@ubuntu:~/Downloads/saf$ python manage.py runserver

Hi Fred,

Are there any lines below the error message you pasted?

The last line I can see is:

File "/usr/local/lib/python2.7/dist-packages/django/utils/importlib.py", line 40, in import_module 

    __import__(name)

Is there anything else?

Cheers,

Victor

There is one other line:
ImportError : No module named bootstrapform

Hi Fred -

So if you can't activate your virtualenv, and you installed Django in that virtualenv, that is likely the root of your problem, because without it, none of the modules will appear as installed and you will not be able to run the server (or access the python manage.py shell, etc).  I would first figure out why you can't activate the virtual environment -- what is the error when you try to activate it?

Rene

[Fred DJar]

Thanks Rene
The virtualenv was created in Ubuntu but now i'm running windows, should i run it in Ubuntu because i've noticed that virtualenv folder structure differentiate from Ubuntu to windows
this is the message i got from the prompt command: activate is not recognized as an internal or external command, operable program or batch file

[Rene Zelaya]

Hi Fred,

Yes, definitely, I think you should run it on a Ubuntu terminal - I'm not that familiar with the Windows terminal

[Fred DJar]

Iv'e run it on ubuntu terminal but still not working

[Lee]

Please be more specific about your problem as its difficult to help when we don't know exactly what you are seeing. Have you managed to activate your virtualenv on ubuntu? If not, what specific error are you getting?

I see two problems here so far, regarding the import error, that means you are missing a dependency of the project you are trying to run. But that may just be that you've not activated your virtualenv - though you need to install the dependencies there once you get virtualenv running anyway most likely. The 'activate is not recognized as an internal or external command, operable program or batch file' error just means the activate script  was not found. You have to either be in the location where the activate script is, or else you need to specify the path to it, which will be in the bin folder of wherever you created the virtualenv. 

BTW, not wanting to confuse matters, but virtualenvwrapper is a useful addition on Linux, but its worth understanding virtualenv first.

[Fred DJar]

Thank you for your response 
i've made a screenshot to illustrate clearly what happening

btw i'm not familiar with virtualenv in ubuntu i've only used it on windows and in order to activate the virtualenv i just run the activate the command.
maybe this is not the case in ubuntu!! maybe it should be run from the bash. if so can you tell me how because i have no idiea

Enter the following command from the bin folder:

source activate

Thanks

Lol, thanks that was super easy
but now i have another problem, i'm missing some packages even though i'm in the virtualenv

here is a screenshot demonstration

Next command: pip install -r requirements

From the directory where the requirements file is of course... And assuming the requirements file has all the requirements of whatever you are trying to run in it

[Lee]

Also be aware that from the stack trace, it looks like you have django installed into the global site packages rather than your virtualenv. The main point of virtualenv is to avoid that and have isolated environments. But it's not really a problem as long as you are aware of the fact that you are using the global site packages

[Fred DJar]

so i'm in the directory /usr/local/lib/python2.7/dist-packages/django/core/management
and now i should run the command pip install -r requirements 
and replace requirements with the missing file (for example base.py) 
is that it??

i'm sorry if my questions seems dumb

[Fred DJar]

yes i know because i've installed django before trying to work the virtualenv problem

[Lee]

No, you were in the right locatin before. Look at your last screenshot. There was a file called requirements and you do it from there. If it does not work, please confirm what is in that requirements file

[Fred DJar]

I've got an error message running the last command. here is the screenshot

[Andreas Kuhne]

You are not running your commands in a virtual environment. You can't run pip outside the virtual environment because that requires root permissions. If you type "sudo pip install -r requirements", it will install the files, but I'm not sure you want to do that. 

Every shell you open, you have to run "source activate" from the bin folder. Otherwise you will be running on the systems default.

So before you write "pip install -r requirements", make sure you are in the bin folder and write "source activate".

Andréas

You can always see if your shell is running with a virtual environment, by the (env) in front of the prompt. If you check your last screenshot, you will see that you are running in a virtualenvironment there.

I got this error message trying to fetch the requirements

So it looks like its uninstalling the Django you already have installed in the global packages, in order to install the version specified in the requirements file, but is hitting a permissions error in doing so because you are not logged in as root (or elevating with sudo). I presume your virtualenv was set up using global site packages if its picking that up. So you have 2 options.

1) Elevate your permissions to delete the existing django in the site root with the following command (im not sure if you need to deactivate your virtualenv or not to do that since I never install anything globally):

sudo pip uninstall django

Enter your password when prompted

Then with your virtualenv activated try the previous command again:

pip install -r requirements

2) delete your virtualenv, and create a new one, specifying no site packages so you have an isolated virtualenv rather than the one you have now:

rmvirtualenv env

Then the following to create the new one, activate it and then install your requirements:

mkvirtualenv --no-site-packages env

source activate (from the bin folder as usual)

pip install -r requirements

Thanks

Trying your first solution gave me this error messages !

And trying the second solution gave me the message that rmvirtualenv : command not found !

[Lee]

Whoops sorry, should have thought, rmvirtualenv and mkvirtualenv come with virtualenvwrapper, not the default virtualenv...

Regarding the first error, was that the whole error or was there some more after where the screenshot cut off? Looks like it tried to install django that time so I guess the uninstall of the global version helped to some extent. 

Regarding the second option, ignore deleting the existing virtualenv (though you can just delete the original directories it created for it if you like) for now and just create a new one with a different name with the following:

virtualenv --no-site-packages newenvname

activate it as before then try running pip install -r requirements again  

[Fred DJar]

Thanks
the second solution worked fine and the requirements were installed

but again when i tried to run the server this is what i got

Can you copy the complete error across? The end of it is all important and its chopped off in the screenshot. 

Thanks

[Lee]

Actually, its probably the same problem as from the start as I see your install from the requirements file only installed Django itself and nothing else. THerefore I presume it does not have a list of all the dependencies you need. Assuming the last error was again "ImportError : No module named bootstrapform", it looks like your project might be using django-bootstrap-form from a quick google. So try the following with your virtualenv active:

pip install django-bootstrap-form

BTW, what is this project you are trying to run. GIven it seems to have external dependencies that you are not aware of, I assume its not your code? If so, I would expect wherever you got it from to have a list of the dependencies that the project needs to run (though usually they would be in the requirements file too)

Thanks

[Fred DJar]

the boostrapform was installed correctly but there's still some problems
as you said this is not my code, and i will try to contact the guy who write the code and get the missing dependencies 

[Fred DJar]

FINALLY 
the server is running

the problem was is two dependencies django-userena and django-bootstrap-form. and the userena dependency was relying on another dependency which is six (the core of the problem) because it didn't installed automatically when installing userena so i had to install it separately


I CAN't THANK YOU ENOUGH LEE
THANK YOU VERY MUCH FOR YOUR TIME
