Tests hangs on MacOS

[assapir]

1. Configure lerna as in my repo (www.github.com/meijin007/story-line)
2. run on MacOS lerna run test.
   Expected: tests from both packages will run
   Actual: only one of them is running, and the other is hanged and time out on the CI

Note - for each package everything is running fine

lerna.json

{
  "name": "root",
  "private": true,
  "devDependencies": {
    "lerna": "^3.15.0"
  }
}

To reproduce. maybe try to add MacOS to the TravisCI

I'm not sure why you're using Lerna, to be honest.

• Only one "package" is actually public, the other is private (and your packages config is quite dangerous, it only needs to be ["api", "ui"] for the current structure).
• lerna exec npm install isn't how you bootstrap lerna packages, you should call npx lerna bootstrap in your Travis config
• I would suggest turning down the concurrency and streaming the output of your lerna run call: npx lerna run --stream --concurrency=1 test:ci

Hi @evocateur, thanks for your comments.
The reason I use Lerna is for easier maintenance of a monorepo, meaning to be able to run commands on both of the packages using a single command.
I will fix my configuration with your comments.

the stream option was allow me to notice where I have timeout in my tests. thanks!

Can you please elaborate why using lerna isn't a good idea for this specific use case?
