Error When Installing App In Production

[swainn]

All: 

I'm attempting to install an app on a Tethys 2.0 production server and I'm getting the following error in the uwsgi logs:

ERROR:tethys.tethys_apps.utilities:The following error occurred while trying to import the controller function "tethys_apps.tethysapp.map_plot.controllers.home":

 Traceback (most recent call last):

ImportError: cannot import name cdec

The strange thing is that I can't find any reference to the name "cdec" anywhere in the app, and it obviously isn't on line 7. It also isn't a valid Python library on conda or pip. As far as I can tell, all of the dependencies have been installed for the app. Has anyone else seen this error before?

This is an issue with a dependency called ulmo. There seems to be an issue with uwsgi recognizing ulmo and possibly other dependencies in the conda environment. I checked the site-packages directory, and the ulmo module is present and its package called cdec is present, but uwsgi does not recongize, even after restarting.

Nathan, I'm having a similar issue as this. I'm able to install my app in a dev environment, but when I try to install it on a production server, I get an error saying it can't import a class that is defined in my model.py file. It is able to import a different class from the model.py file.

Ezra, can you post more details? What is in your models.py, where are you making the import, how are you installing in production, what is the error, etc.
