The problem

After rebasing and using the latest changes with Angular 6.0.4 I started to get the following error coming from the yamljs package when I'd try to rebuild with yarn ng build --aot=false --vendor-chunk=true --source-map=true or even just syndesis build --clean, which uses the same command.

Screenshot

ERROR in ./node_modules/yamljs/lib/Utils.js
Module not found: Error: Can't resolve 'fs' in '/Users/kahboom/Projects/syndesis/app/ui/node_modules/yamljs/lib'

See my comment here for more details.

I also got a few other weird things related to SASS:

Module build failed: Error: Node Sass does not yet support your current environment: OS X 64-bit with Unsupported runtime (64)

EDIT: This should be resolved with this PR #2886 .

@kahboom run yarn install --force before running yarn start:minishift to sort the node-saas issue.

@kahboom is this still a bug or do @gashcrumb suggestion fixes it?

Well, if this is the same issue I'm thinking of, I was trying to come up with a fix that would work for everyone without having to use the --force flag. I think this is related to the version of Node and npm each person uses and dependencies that try to force certain engine versions. Either way, this commit would have sorted out for local env, but not for CD/CI: https://github.com/syndesisio/syndesis/pull/2886/files#diff-4c51b5da64219cce10752e61a6393f5c

I guess either way we can consider this closed and just have people run those commands manually, or that fix above should sort it out.
