while working with brightway2 I realized my version was not up to date and tried to update it using conda update brightway2 but it would not do it.
I have to set a new project and update brightway2 in this new project to have the latest version running.
My question is simple: is there a way to update brightway2 without having to create a new project?
Once you have updated brightway data, running bw.bw2setup() in a new project will give you the most up-to-date methods and biosphere exchanges.
You cannot run bw.bw2setup() in a project where bw.bw2setup() has already been run. This is simply because the biosphere3 database already exists.
Let's suppose you imported brightway2 as bw:
`import brightway2 as bw
To update your biosphere exchanges, you first need to delete your existing biosphere3 database:
bw.Database('biosphere3').delete()
bw.Database('biosphere3').deregister()
If you run bw2setup() now, you will not update your methods, though - brightway will complain about the methods you are trying to save already existing, and quit. I have not found a way to delete the methods using brighway2 methods, but simply deregistering them works:
all_method_tuples = list(bw.methods)
for m in all_method_tuples:
bw.Method(m).deregister()
Now you are ready to import your biosphere exchanges and methods:
`bw.bw2setup()
