A question about the UI build - Why sometimes we need to explicitly do

npm install

to build the UI after a new node module is added? I mean, looking at the Makefile I expect the following to happen on

make build

- make build -> gen > gen-ui -> ui-build -> $(UI_DIR)/node_modules (that does npm install)

We excluded the

npm

package install from the default build step as it is a very long process. A new build machine will not have a node_module and we condition that in the makefile to install npm packages. We can add it to the clean step so an incremental build will not install it and a fresh clean will work for you?

What about performing npm update instead of install in existing envs?

npm update will update the versions of the packages. we like to update your environment with new packages specified in package.json

We can add it to the clean step so an incremental build will not install it and a fresh clean will work for you?

That makes sense, thanks for the explanation!

I think in this specific case - the problem was that we needed to update an existing package, @Tal Sofer correct me if I'm wrong?

We needed to install new package

I guess I misunderstood the error
