Hi! I'm stuck importing packages within site-packages (the web2py one). I'm trying to import the Request library:

I don't get why is telling me is trying to import from applications.myapp.modules.requests, when the package is not even there.

Thanks!

The application's modules folder is the last place the importer looks that's why you get the error there. Have you restarted web2py after putting requests in the site-packages folder?

Hi. Thanks for anwser. Well, I was trying to import "requests" in PythonAnywhere. I found that they have it pre-installed (I did'nt know). So, problem solved by now. I could'nt import the standalone request package inside site-packages or the app specific "modules" directory neither.

I have same problem. From command line the modules are imported correctly. Using python web2py.py also loads the modules. But nginx + uwsgi doesn't work.

I had the same issue.
Can you have a look at the installed packages:

python
>>> import pip
>>> pip.get_installed_distributions()

My requests module was installed at /home/myusername/.local -> but when I run web2py with nginx+uwsgi it is running with user "www-data".
I solved the problem by uninstalling requests and reinstalling it using sudo su:

sudo su
# pip install requests
