mbt: not found

[ThePlenkov]

Hi!

In my projects I use workspaces.

So i have few nodejs apps. The problem starts at build:

cap-xsa: > cap-xsa@1.0.0 mbt
cap-xsa: > mbt build --platform xsa --mtar=${npm_package_name}.mtar

So what just happens - is mbt being called - calls npm install --production for the module, but that module is a workspace - and it delets all non-production packages from node_modules and because of this mbt is not available anymore because is dev dependency.

So what I need is to force somehow mbt not to install dependencies anywhere. How to do this?

Thanks!

I suggest you should remove the mbt from your devdependencies in package.json and install mbt global with command line "npm install -g mbt" .

No actually I don't want to do this because this is how we build apps - we keep builder components in a dev dependencies so no surprises in CICD on version upgrades. But actually I found the reason- this not directly related to mbt but mainly to a builder config where before script is npm ci --production. The problem is - in combination with workspaces - it basically runs this command in a root folder and it removes all dev dependencies including mbt.

So the solution is to call npm ci but for the whole project ( or not call it at all ), that's it
