`lerna run` doesn't execute peers in topological order

I have several packages, most of which only depend on the core package at the moment. Each package is individually built using the Angular CLI.

• @denverhjs/core
• @denverhjs/foo
• @denverhjs/baz
• @denverhjs/bat

Expected Behavior

Lerna can determine that @denverhjs/core must be built before any of the packages that list it in their package.json peerDependencies list.

Current Behavior

Executing the build script yields the following error output:

lerna ERR! npm run build stderr: src/lib/bat.module.ts(3,37): error TS2307: Cannot find module ‘@denverhjs/core’. src/lib/bat.module.ts(8,5): Error during template compile of ‘BatModule’ Could not resolve @denverhjs/core relative to [object Object]… src/lib/bat.module.ts(8,5): Error during template compile of ‘BatModule’ Could not resolve @denverhjs/core relative to [object Object]…

Possible Solution

Execution proceeds without error when the command: lerna run build --scope @denverhjs/core && lerna run build --ignore @denverhjs/core

However that is not sustainable as the dependency graph grows in depth.

Steps to Reproduce (for bugs)

1. Fork and clone this repo: https://github.com/denver-HJS/lerna-demo
2. execute npm run build or lerna run build

lerna.json

{
  "packages": [
    "projects/*"
  ],
  "version": "independent"
}

Context

I’m trying to leverage this great library to provide a CI solution for an Angular monorepo that contains multiple Angular NPM packages.

Your Environment

Executable	Version
lerna --version	3.13.1
npm --version	6.4.0
node --version	9.11.1

OS	Version
NAME	VERSION
macOS Sierra	10.13.6
Windows 10	1607

@evocateur, thank you for reading that closer than I did! 😃

It does work correctly now when I’ve added the desired higher order dependency to the leaf packages’ devDependencies list. Thank you for the help.

I have similar issue where in there packages |- module#1 |- module#2 |- module#3

now when I try to run lerna run build Since module#3 is marked as dependency of module#1, command build needs to be executed first for module#3 so it to be available for consumption for module#1

Question - Is this supported in lernaJS ? If yes, how can i achieve it?
