Hello, I’ve got a general question about

add

and

install

commands. Specifically, the difference between scenario: • Run

meltano add x y

, which adds

x y

into meltano.yml file and then installs it • Add

x y

into meltano.yml file manully and then running

meltano install

The second option sometimes works, sometimes it refuses to find that

x

plugin. I haven’t had time to properly test this out so I’m asking the community. What is the difference in background tasks? And what task is missing in second approach?

Running

meltano install

will install everything in your project, as opposed to the single plugin install that occurs when running

meltano add

. You can install a single plugin using

meltano install <type> <name>

. If you're adding plugins into

meltano.yml

by hand (manually), there's also the possibility that the definitions are just incorrect. Given that your project contains just one plugin, in theory both approaches are the same, since add by default installs plugins after adding them to your project. As of version

2.5.0

, you can use

--no-install

with

meltano

add

to skip the install step, which might be worth trying with your second scenario.

Hm, thanks for the reply, however still doesn’t explain the error I got when: • I manually added superset into meltano.yml • Build docker image which included

meltano install

and installed superset successfully • Once in the container, meltano was telling me that it can’t find plugin superset. If the definitions were incorrect, wouldn’t it fail to install?

Can you show your

meltano.yml

, as well as the command log when you run

meltano invoke superset:load_datasources

with

--log-level debug

?
