Django Migration Error - NodeNotFoundError
You are getting the error because the migration you are trying to run, weather.0001_initial
, depends on a migration machines.0006_auto_20150921_1327
which does not exist.
If you can't find the missing migration file, you'll have to delete and recreate the migrations for the weather
app, so that they don't depend on the missing migration.

Trying to migrate a newly added app in my project. Here is the traceback error:

I have not found much helpful information in researching this. Syntax is correct in all models. Here is what doesn't make sense: this is just a copy of a working project. So it works on one computer, but not here. The machines model it's referencing has already been created and is working. Any ideas???
